Summary

  • keep mcp on the stable 1.x API expected by langchain-mcp-adapters
  • exclude the Pydantic 2.14 prerelease that leaves MCP request models unresolved

Local verification

  • started with azd ai agent run on an isolated local environment
  • readiness returned HTTP 200
  • a representative Responses request completed with GitHub MCP get_me and search_repositories tool calls

Keep the MCP SDK on the API expected by langchain-mcp-adapters and avoid the Pydantic 2.14 prerelease that leaves MCP request root models unresolved during startup.
