MCP Method logging/setLevel not found

[vorburger]

To work around #1907, I am attempting this in Enola's mcp.yaml:

  github:
    docs: https://github.com/github/github-mcp-server
    # TODO https://github.com/enola-dev/enola/issues/1907
    # url: https://api.githubcopilot.com/mcp/
    # headers:
    #   Authorization: Bearer ${secret:GITHUB_PAT}
    command: docker
    args:
      [
        "run",
        "-i",
        "--rm",
        "-e",
        "GITHUB_PERSONAL_ACCESS_TOKEN",
        "ghcr.io/github/github-mcp-server",
      ]
    env:
      GITHUB_PERSONAL_ACCESS_TOKEN: ${secret:GITHUB_PAT}

but it's causing:

#1899 (comment) after all?! But the method IS still there... there is no NoSuchMethodError. So it's not not the Java API but the remote MCP server that does not have a logging/setLevel JSON RPC method?

[vorburger]

https://github.com/modelcontextprotocol/java-sdk/releases/tag/v0.11.3 had this:

• Disabled logging capabilities for stateless servers (fix: disable logging capabilities for stateless servers modelcontextprotocol/java-sdk#517)
  • Removed LoggingCapabilities from stateless server features to align with actual functionality
  • Stateless servers don't support setLogging operations, so capabilities are now correctly advertised
  • Prevents client confusion and aligns async implementation with sync implementation

BUT that's ancient (#1899 bumped from 0.14.1 to 0.15.0; NOT 0.11.3), so I'm not convinced that's related.

I doubt that #517 and #463 are related to this either.

Oh! I think I know what was going on here:

It was just the 6 months old github-mcp-server container image, which used an MCP spec version that didn't have this, yet.

Things move fast in this space! 😆

Closing, as nothing to do.
