Approving only for Openapi-mcp-server has it it a patch upgrade. for other mcps, it may have breaking changes and need separate reviews.

Use module-level fastmcp.settings for debug config instead of removed
FastMCP instance attributes. Update bvs_tools tests to use __fastmcp__
attribute for tool name assertions.
The aws_pricing function expects filters as Optional[str] (JSON string),
but the test was passing a dict, causing a pyright type error.

@mayakost , I think this may have significant changes as the new major version has breaking changes. I have only done it for OpenAPI-MCP-Server as it has considerable changes including adopting a few important new features. I see a minor patch upgrade in openapi-mcp-server uv.lock. I would simply take that as a separate simple PR. I also suggest server-wise upgrades where it is impacting the code. @scottschreckengaust ,
