Extract the MCP client and registry into tinymcp by senamakel · Pull Request #5671 · tinyhumansai/openhuman

senamakel · 2026-08-22T00:58:54Z

Moves the MCP client, server registry, and write-audit log out of this
repository and into tinymcp,
consuming it as a vendored path dependency pinned to the v0.3.1 release.

Net −11,125 lines of MCP implementation here.

What moved

Both MCP transports, the SQLite server store, the Smithery and official
catalogs, the connection supervisor, the browser sign-in flow, the setup secret
vault, the write-audit log, and the LLM-facing sanitizer. src/openhuman/mcp/server/
stays — that is OpenHuman as an MCP server, and it is coupled to this
repository's tool registry and agent machinery.

What stayed, and why

The seams that are genuinely this application's: the prompt-injection scan over
remote tool definitions, DomainEvent publishing, the config_assist model
turn, the proxy-scoping decision, the OAuth redirect URI, and waiting on a
user-supplied secret. tinymcp takes an already-resolved proxy rather than a
policy, because whether a proxy applies to a service is decided by settings that
live here.

Public API and behavior changes

No RPC method signature changed. schemas.rs, tools.rs, and stub.rs
needed no edits, so the frontend and the wire contract are untouched. Payload
types are re-exported from tinymcp_bus under the names this code already used,
so SmitheryConnection and friends keep their spelling.

Three behavior changes worth calling out:

The MCP service is keyed by workspace. The library owns what used to be
process globals, so this repository needed somewhere to hold one. The first
shape was a single OnceLock, and its own suite proved that wrong: every entry
point into this domain is addressed by configuration, and one process serves
more than one workspace over its life — the workspace can be switched in place,
and the test suite runs each case against its own. src/openhuman/mcp/host.rs
keys services by workspace instead.
host::init is now wired into startup. The old
registry::bus::init() call site was removed during the extraction and not
replaced, which would have left the service never initialised. It is called
from the MCP domain enable point and from the boot-jobs path, and the deleted
lifecycle subscriber that logs this domain's events is restored.
Five internal handlers gained a &Config parameter — disconnect,
list_tools, tool_call, and the two secret-vault handlers. Their callers
load the config the way every sibling handler already did. No wire change.

On-disk state

mcp_clients/mcp_clients.db is read as it stands, not migrated: an installed
server is state a user set up, and losing it means re-authorizing every
integration by hand. tinymcp carries a test built from this repository's
original schema — including rows predating the transport, deployment_url,
and enabled columns — asserting the same servers and credentials read back.

The audit log moves to its own file, mcp_audit/mcp_audit.db. Rows written into
the memory-tree database before the move stay where they are; an audit log is
history rather than operational state, and nothing reads the old table.

Defects fixed upstream on the way

Each with a regression test in tinymcp. The two most serious:

A remote-triggerable panic and silent corruption in the tool-description
sanitizer: the scan took a byte offset from a lowercased copy and spliced it
into the original, so any character whose lowercase form differs in UTF-8
length shifted every later offset. Tool descriptions come from user-installed
servers, so this was reachable by a third party.
A credential leak into error messages: reqwest::Error's Display
renders the full request URL including any ?api_key=…, defeating the
endpoint redaction the error type was applying.

Also: a process abort on a malformed proxy URL, orphaned stdio subprocesses, an
unvalidated protocol version on the stdio transport, and a lock released
mid-way in the secret vault's resolve-and-drop.

Kernel floor: raised by two, temporarily

scripts/kernel-floor.limits goes 283/265 → 285/267 for the flows profile,
and dep-sim.py --expect-names follows it. The two names are tinymcp and
tinymcp-bus.

No new third-party code enters the profile: tinymcp resolves reqwest,
rusqlite, tokio, serde and uuid, every one of which this profile already had,
and tinymcp-bus is the wire contract — its own CI asserts it holds no
transport, no async runtime, no HTTP client and no native library. The two
native packages are unchanged.

The raise is its own undoing. Step two loads tinymcp as a TinyBus module from
its release artifacts and drops the path dependency, keeping only
tinymcp-bus — at which point this comes back to 284/266 and the MCP transport
stack leaves the always-on graph entirely.

Validation

cargo build --lib — clean
cargo clippy --lib --all-features -- -D warnings — clean
cargo test --lib mcp — 192 passed, 0 failed
mcp_registry_e2e, mcp_registry_multi_server, mcp_setup_e2e,
mcp_stdio_integration — 24 passed, 0 failed
cargo test --lib — 11,033 passed, 4 failed

The four are environmental and none touch MCP: two git_operations cases where
git refuses to discover a repo across the tempdir's mount boundary, one
sync_pipeline seal timeout, and one claude_agent_sdk case that hits
"Text file busy" writing a fake binary to /tmp. All four reproduce serially,
and none of those files are in this diff.

cargo clippy --all-targets additionally fails on pre-existing errors in
wallet_tests.rs, subconscious_fullstack_e2e.rs (an await in a non-async
fn), live_flows_demo_e2e.rs, and a duplicate_mod — none touched here.

One unrelated frontend fix, and why it is here

app/src/pages/Feedback.test.tsx mocks feedbackApi without validateFeedback.
The submit form debounces an advisory quality check on the draft; its .catch
covers a rejected call, not a missing method, so the timer callback throws
synchronously and lands as an unhandled error after the test that rendered the
form has already passed. Every test file passes and the run still fails.

That is a defect on main, not from this change — this branch touches no
frontend source. It blocks here because the frontend lane runs on changed files
and this branch's change set selects that suite. Adding the missing mock entry
is a two-line fix, verified locally (12 tests, no unhandled error), and it is
its own commit.

Not in this change

Step two of the plan: loading tinymcp as a TinyBus module from its release
artifacts and dropping the path dependency, keeping only tinymcp-bus. That
needs a ModuleRecord with per-platform digests taken from the release's
checksum.toml, and is a separate change.

Move the Model Context Protocol client implementation into the tinymcp external library, replacing the in-tree code with a dependency on the extracted crate. The audit log, config-declared server set, dynamic registry, supervisor, OAuth, and transport code now live in the vendor library, while the host retains only the RPC surface, agent-facing tools, and prompt-injection scanning. This reduces the in-tree MCP code by over 12,000 lines and allows the library to be versioned and tested independently. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

….rs,src/openhuman/tools/ops.rs Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

Change the `GitbooksSearchTool::new` and `GitbooksGetPageTool::new` constructors to return a `Result` so that a malformed proxy URL or unusable TLS setting produces an error rather than a panic. In the registration code, both tools are now built together and only registered if both succeed, with a warning logged otherwise, so a misconfigured documentation server no longer takes down the entire tool surface. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

The test code contained escaped double quotes inside string literals that did not require escaping, as the strings were already delimited by single quotes. Removing the backslashes makes the code cleaner and avoids potential confusion for readers. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

Add a `From<tinymcp_bus::McpToolResult>` implementation for `ToolResult` to centralize the conversion between the two types, which share the same shape but now live in different crates. Update the gitbooks and MCP tool implementations to use the new conversion instead of returning the raw MCP result, and fix the MCP server listing to use the extracted auth config type and handle unknown enum variants gracefully. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

Extract the host construction logic from `init` into a public `McpHost::open` method so that integration tests can create a fresh host per test case without relying on the process-wide `OnceLock`. This allows each test to start with a clean store and avoids sharing state across cases. The change also moves `CommandKind` to the `tinymcp_bus` crate and updates all test helpers to use the new `host` function, removing direct imports of internal registry modules. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

The connect method now returns a structured result instead of a flat tool list, so all call sites that only need the tools field must explicitly access `.tools`. The supervisor reconnection test is updated to use a new `supervise_once` helper that drives a single tick directly on the host, avoiding the timer-based `run_single_tick_for_test` and making the test faster and more deterministic. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

Replace direct calls to global store and connection functions with the host fixture's dynamic accessor, and move the secret-vault logic from the registry setup module into a dedicated tinymcp vault that is owned per test rather than process-wide. This eliminates shared mutable state between tests and aligns the e2e suite with the refactored internal APIs. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

Switch `McpHttpClient` from a positional constructor to a builder pattern, add `.expect()` calls where construction can now fail, and replace relative `super::` audit module references with fully qualified paths. The test for host configuration is rewritten to verify that both stores are actually created under the workspace directory rather than just checking a config field. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

The end-to-end test now builds the client identity through the host's client_config conversion rather than cloning it directly from the configuration. This ensures the test constructs the identity using the same path the application follows, keeping the test aligned with production behaviour. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

Reformat long method chains and function calls to use consistent indentation, reorder imports to follow standard conventions, and remove unused imports and stray blank lines. These changes are purely cosmetic with no behavioural impact. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

Open the MCP host service and its audit log at domain registration time rather than deferring it to the boot-connect job, closing a window where RPC handlers would answer "still starting" to callers whose domain is already up. The audit log is now workspace-scoped and opened on first use, so a process serving multiple workspaces records writes under the correct one. The `mcp_clients_list_tools` handler tolerates an absent service with the same "connect it first" error that an unknown server gets, avoiding a misleading "still starting" distinction. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

Add tests for the audit log behaviour: that it opens under the correct workspace, that repeated calls reuse the same log, and that different workspaces produce distinct logs. The existing store test is narrowed to match the new single-store design. The tinymcp submodule is advanced to include the AuditStore type these tests exercise. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

…ctions Add two new public functions to the connections module that allow callers to connect to a server and retrieve its advertised tools, and to disconnect a server by its identifier. The connect function records a failed attempt so that polling callers can see the reason without retrying, while disconnect returns false when the service is not running to accurately reflect that no connection was held. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

… infrastructure This change introduces three major MCP subsystems: an audit log for recording MCP write operations with filtering and pagination, a config server registry that manages both HTTP and stdio-based MCP servers with tool allow/deny lists and safety scanning, and an HTTP client module for remote MCP server communication. The audit store provides persistent tracking of tool calls with support for client and tool filtering, success/failure status, and error message truncation. The config server registry builds from TOML configuration, supports legacy GitBooks integration, and enforces tool-level access control along with prompt injection scanning on tool definitions. The HTTP client handles the full MCP protocol lifecycle including initialization, tool listing, tool calls, and OAuth-based authorization discovery. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

Replace the single `OnceLock<McpHost>` with a `OnceLock<Mutex<HashMap<PathBuf, Arc<McpHost>>>>` so that every workspace gets its own service instance, and fold the audit store into `McpHost` as a field rather than keeping it in a separate global map. All RPC handlers now resolve the service through a new `for_config` function that looks up or opens the service for the caller's workspace, ensuring that writes, connections, and tool listings always act on the correct store even when the process serves multiple workspaces over its lifetime. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

The `mcp_clients_tool_call` function now requires a `Config` reference, and `McpRegistryToolCallTool` has been updated to hold an `Arc<Config>` so it can pass configuration through to the underlying call. This enables the tool call path to access configuration-dependent behaviour such as timeouts or authentication settings. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

The MCP setup handlers for requesting and submitting secrets now accept a config reference, ensuring they operate on the correct workspace rather than a global default. This aligns the secret flow with the existing pattern used by search, get, test connection, and install operations, making all setup handlers consistent in how they resolve the host service from configuration. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

…lisation The MCP registry modules previously relied on a global service handle obtained through `host::service()` or `host::try_service()`, which could fail silently or panic when the service was not initialised. These calls are replaced with `host::for_config(config)`, which takes the configuration explicitly and returns a proper `Result`, allowing callers to handle errors gracefully with informative log messages. The `McpSetupRequestSecretTool` is also updated to accept the configuration, ensuring consistent access to the service throughout the setup tools. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

Switch test helpers from constructing a fresh `McpHost` per call to using the shared `for_config` resolver, so that connections opened directly in tests are the same instance that RPC handlers see. Also fix a unit test that was missing the config argument when constructing `McpSetupRequestSecretTool`. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

…the store The end-to-end test for clearing the last error on successful connect was not persisting the server record changes to the store, so the test could pass even when the production code path that reads from the store was broken. The fix inserts the modified server record into the store before the first connect attempt and properly cleans up and reinserts the valid record before the second connect, making the test exercise the actual store-backed resolution path. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

Reformatted the `mcp_clients_disconnect` call and the `insert_server` test call to break long method chains across multiple lines, and removed an extra blank line in `host.rs`. These are purely cosmetic changes that improve code readability without altering any behaviour. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

Co-authored-by: Medulla <medulla@tinyhumans.ai>

Update the tinymcp dependency and its submodule pointer to version 0.3.1, along with the corresponding tinymcp-bus crate version in the lockfile. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

📝 Walkthrough

Walkthrough

The MCP implementation moves local clients, registries, stores, and supervisors into vendored TinyMCP services. A workspace-scoped McpHost owns MCP services and audit storage. RPC handlers, tools, startup, and tests use the new host APIs.

Poem

A rabbit hops through hosts anew,
TinyMCP guides each queue.
Tools and secrets cross the gate,
Hosts keep every workspace state.
Startup wakes the service bright,
Audit trails record the night.

When a tool call has no arguments, the MCP handler now returns an empty object instead of failing. This fixes a crash that occurred when tools were invoked without any parameters. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

When a service is not registered in the runtime, attempting to shut it down now returns an error instead of panicking. This change improves robustness by allowing the runtime to continue operating even when individual services are absent, which can occur during partial initialization or cleanup. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

When a service is not registered in the runtime, attempting to shut it down now returns an error instead of panicking. This change improves robustness by allowing the runtime to continue operating even when a service reference is absent, which can occur during partial initialization or cleanup. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

When the runtime service is not registered, the shutdown sequence now skips the service stop call instead of panicking. This prevents a crash in environments where optional services are conditionally loaded. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

The test for tool call handling was asserting the wrong field in the response, causing a false negative. The assertion now checks the correct property to ensure the test validates the intended behavior. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

Reformatted the multi-header credential test assertions to use a more consistent indentation style, wrapping the iterator chains across multiple lines instead of keeping them on a single line. This improves code readability without changing any test behavior. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

Updated the raw coverage end-to-end test to reflect changes in agent behavior during round 26, ensuring the test assertions match the current expected output. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

When an MCP server is not configured, the host now returns a clear error message instead of panicking. This improves robustness by allowing the system to continue operating with other configured servers. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

When the MCP host shuts down, it now checks whether the server instance exists before attempting to stop it, preventing a panic on a consumed or absent `Option`. This ensures clean teardown in edge cases where the server was never started or has already been taken. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

When the MCP host is shut down before a server has been fully initialized, the shutdown routine now checks for a missing server handle and skips the shutdown call instead of panicking. This prevents a crash during early termination or rapid restart sequences. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

When the MCP host is shut down before a server has been fully initialized, the shutdown routine now checks for a missing server handle and skips the cleanup step instead of panicking. This prevents a crash during early termination scenarios. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

When the MCP host is shut down before a server has been fully initialized, attempting to access the server's process handle causes a panic. This change adds a guard to check for the server's presence before attempting to terminate it, ensuring a clean shutdown in all initialization states. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

When the MCP host is shut down before a server has been fully initialized, the code now checks for a missing server handle before attempting to stop it. This prevents a panic caused by unwrapping a `None` value in the shutdown sequence. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

When the MCP host shuts down, it now checks whether the server process is still running before attempting to terminate it. This prevents a panic when the server has already exited, ensuring clean shutdown in all cases. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

Updated the test assertion to match the actual response format returned by the host, ensuring the test correctly validates the tool call result. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

When a tool is registered with a name that already exists in the registry, the system now returns an error instead of silently overwriting the previous entry. This prevents accidental loss of tool definitions and makes the registration contract explicit. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

When the MCP server configuration is absent, the application now logs a warning and continues without crashing. Previously, a missing server entry caused a panic during initialization, preventing the application from starting even when MCP functionality was not required. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

When the MCP host shuts down, it now checks whether the server instance exists before attempting to stop it, preventing a panic on uninitialized or already cleaned-up servers. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

The test assertion was incorrectly checking for a tool call response when the actual response was a text response, causing the test to fail. Updated the assertion to match the expected response type. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

Updated the test assertion to match the actual response format returned by the host, ensuring the test validates the correct field name and prevents false failures. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

Reformat the `resolve` function signature to fit on one line, and reorder imports in the test file to follow the project's convention of grouping related imports together. No functional changes are introduced. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

305-305: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Preserve coverage for workspace memory.

The change removes the only assertion for ## Memory context. This test still writes MEMORY.md and sets include_memory_md: true, so it can pass if the workspace-memory section disappears while learned-memory assertions remain. Keep the assertion, or assert the replacement marker if the prompt contract changed.

CodeRabbit COMMENTED findings (both non-blocking) — disposition against head 4f4ea2a45:

cr-comment:v1:f4621025b27701fbafb45c22 — tests/mcp_registry_e2e.rs "assert the live connection is dropped" (🔵 Trivial, reviewed against a711e8d8b). The proposed assertion is already in the file at the current head:
```
assert!(
    !h.dynamic().connections().is_connected(&server.server_id).await,
    "disabling a running server must drop its live connection"
);
```
(tests/mcp_registry_e2e.rs:391-394). The review predates the merge of main, which is what brought the assertion in. No code change needed.
cr-comment:v1:e9c95382ad869bccab455d66 — tests/raw_coverage/agent_round26_raw_coverage_e2e.rs "preserve coverage for workspace memory" (🟡 Minor). Fixed in 4f4ea2a45: the ## Memory context marker was removed deliberately with the subconscious domain removal — the section it named no longer exists, and its replacement (UserReflectionsSection, "## User Reflections") is config-gated, so it cannot appear in this test's default builder chain. To keep the finding's substance — that the test's include_memory_md: true + on-disk MEMORY.md actually proves the memory gate renders — the test now builds a second prompt with the personality override and curated snapshot cleared, forcing the workspace-file branch of UserFilesSection, and asserts ### MEMORY.md, the file body "workspace memory round26", and the "background — not this conversation" framing. The personality-override branch stays asserted via "round26 personality memory override". Passes locally: cargo test --test raw_coverage_all prompt_renderers_cover_user_memory_identity_tools_and_subagent_variants --features voice,inference → 1 passed.
