Please can we push this one through? It makes local MCP servers for Google SecOps a non-starter, unless there's a published workaround? |
Pin explicit version constraint for mcp to prevent incompatible mcp 2.x installations from breaking FastMCP import at runtime. - mcp>=1.23.0,<2.0: Restrict to compatible v1 FastMCP API - Remove standalone fastmcp and uvicorn dependencies (not used directly by gti-mcp) Fixes #277
