Bumps the python-dependencies group with 2 updates: mcp and pydantic.

Updates mcp from 2.0.0 to 2.1.1

Release notes

Sourced from mcp's releases.

v2.1.1

What's Changed

Full Changelog: modelcontextprotocol/python-sdk@v2.1.0...v2.1.1

v2.1.0

Highlights

  • Client accepts StdioServerParameters directly: Client(StdioServerParameters(command="uv", args=["run", "server.py"])) (#3321).
  • Prompt messages accept Image and Audio, prompt functions may return bare content blocks, and Message / UserMessage / AssistantMessage are exported from mcp.server.mcpserver (#3320).
  • The 4 MiB request body limit now also covers the SSE transport and the OAuth endpoints; SseServerTransport and MCPServer.sse_app() take max_request_body_size, and the SSE message endpoint answers 405 to non-POST requests (#3336).

Behaviour changes to be aware of

  • Handler exceptions (#3314): an unexpected exception from a tool, resource or prompt handler is logged once at ERROR with its traceback, and the client now sees only Error executing tool <name> (or the resource/prompt equivalent) rather than the exception text. Raise ToolError / ResourceError when the message is meant for the model; those still reach the client and are logged at INFO without a traceback.
  • Content-block return annotations (#3320): a tool annotated to return TextContent, EmbeddedResource, Image, Audio, or lists/unions of them no longer advertises outputSchema or returns structuredContent; its content is unchanged. Pass structured_output=True to keep the previous shape.

Fixes

  • TypedDict tool results: NotRequired keys are omitted instead of serialized as null, and registration no longer fails on Python 3.10 (#3224, #3227); recursive return types get an object-rooted outputSchema that pre-2026 clients accept (#3337).
  • 2026-07-28 over HTTP: a POSTed notification such as notifications/cancelled is acknowledged with 202 instead of rejected with 400 (#3324).
  • Pre-2026 sessions ignore cache-hint fields from later revisions instead of failing list_tools() (#3223), and accept boolean sub-schemas in tool schema properties (#3353).
  • mcp install reads and preserves a Claude Desktop config containing non-ASCII text on any Windows code page (#3296).
