Bug Description
When I add the Official GitHub MCP server via the Docker MCP Toolkit
(claude mcp add docker-mcp docker mcp gateway run), internally
Claude creates method names that append the name I chose (here docker-mcp)
to the tools. That results in at least one tool (I believe it's
add_pull_request_review_comment_to_pending_review) whose full name
exceeds 64 characters. That results in a 400 error complaining about
a name too long, and nothing works properly after that.

for Claude Code to run at all. I have no idea why you have a 64 character limit on a string, but the 400
error gives an error message about the 64-character length limit being exceeded.
