Changes Made (convex/mcp.ts:11-114)
1. Added Connection Guard (Line 12)
const pendingConnections = new Map<string, Promise<void>>()
2. Updated connectLLMText with Race Protection (Lines 19-66)
- ✅ Checks if connection is already in progress → waits for it
- ✅ Checks if already connected → returns immediately
- ✅ Stores pending connection promise before starting
- ✅ Cleans up in finally block to prevent memory leaks
- ✅ Concurrent callers now wait for the same connection attempt
3. Fixed extractText to Delegate (Lines 82-85)
// OLD (race condition):
await manager.connect({ ... }) // Multiple callers = multiple connects
// NEW (safe):
await ctx.runAction(internal.mcp.connectLLMText, {}) // Delegates to guarded function
How It Works
Before: Multiple concurrent extractText calls → All see "not connected" → All try to connect → Race condition
After: Multiple concurrent calls → First starts connection, others wait for same promise → Only one connection
attempt
Benefits
- 🛡️ Thread-safe: No duplicate connection attempts
- 🚀 Efficient: Concurrent callers share the same connection
- 🔒 Memory-safe: Automatic cleanup in finally block
- 📝 Self-documenting: Clear inline comments

Changes Made (.github/workflows/setup-github-projects_Version3.yml:31-42)
Before:
env:
GH_TOKEN_SECRET: ${{ secrets.GH_TOKEN }}
GITHUB_TOKEN_SECRET: ${{ secrets.GITHUB_TOKEN }}
After:
env:
MY_GITHUB_TOKEN: ${{ secrets.MY_GITHUB_TOKEN }}
Key improvements:
- ✅ Now uses your MY_GITHUB_TOKEN secret
- ✅ Cleaner error handling if token is missing
- ✅ Clear success message when authenticated
Next Steps
1. Commit the workflow:
git add .github/workflows/setup-github-projects_Version3.yml
git commit -m "fix: Use MY_GITHUB_TOKEN for issue creation"
git push
2. Run the workflow:
- Go to GitHub Actions → "Import Plan to Issues"
- Click "Run workflow"
- Should now successfully create all 136 issues

The workflow requires a custom MY_GITHUB_TOKEN secret but GITHUB_TOKEN is automatically available with the configured permissions (lines 11-13). Unless there's a specific reason to use a custom PAT (like needing access to other repositories), you should use the built-in GITHUB_TOKEN which follows the principle of least privilege and doesn't require manual secret management. Change to use secrets.GITHUB_TOKEN and update the variable name accordingly.

52-134: Connected status blocks fresh workers from ever establishing a sessionWhen
acquireConnectionLockreturns{ acquired: false, status: 'connected' }we bail out (either immediately or after a one-shot wait) without ever callingmanager.connect. That works only for the process that originally set the status. A new Convex Node worker handling this action will find its localMCPClientManagerhas no session forllm-txt, yet we still return{ success: true }. The follow-upextractTexton that worker hits the same branch and eventually callsmanager.callToolwithout a live connection, so the request fails (the manager rejects calls to unknown servers). In other words, once one instance marks the row asconnected, every other instance is permanently locked out of establishing its own MCP connection.We need to let a fresh worker rehydrate its own connection before declaring success. One straightforward fix is to treat the DB record as advisory: if
lockResult.status === 'connected'butmanager.getConnectedServers()is missingserverName, reacquire the lock (e.g. via a dedicated mutation that flips the row back toconnecting) and then runmanager.connect. Alternatively, stash an owner identifier in the connection row so only the owning worker returnsalreadyConnected, while everyone else re-enters the connect path. Without this change, multi-instance deployments will intermittently fail every call routed to a cold worker.

Clear stale error details when status recovers
updateConnectionStatus only patches the error field when a new error string is supplied. After a failed attempt we persist an error message; on the next successful connection we set status: 'connected' but never clear that field. Any consumer reading the record will continue to see the old error even though the status is healthy. Please explicitly null out or remove error whenever we transition to a non-failed state (e.g. include error: undefined for 'connected'/'disconnected').
🤖 Prompt for AI Agents
In convex/mcp_mutations.ts around lines 97 to 101, the patch only sets the error
field when args.error is truthy, so after a failed attempt the persisted error
remains even when status is later set to 'connected' (or other non-failed
states); modify the patch to explicitly clear the error when transitioning to a
non-failed status by including error: undefined (or null) in the update when
args.status indicates recovery (e.g., 'connected' or 'disconnected'), while
still setting error to args.error when a real error string is provided.
