Overview

• Adds support for the mcp http protocol
  • Most agents prefer to use the stdio approach instead (Claude doesn't even support local http servers), and the stdio version is more robust since it doesn't require a UCM to be already running to connect to, but perhaps some agents prefer this method, but it's at least an option now; and it's handy to have for transcript tests.
• Adds transcript tests against the http mcp server
• Refactors the tool setup to something a bit more robust and consistent
• Adds some new tools
• Allows typechecking against a file.
• Upgrades the hs-mcp dependency to a rewrite which should prevent orphaned mcp processes.

Implementation notes

• Mounts the mcp http server interface at /codebase/mcp on the codeserver port.
• Adds POST requests to the transcript parser
• Delimits the BODY: and RESPONSE: in API transcripts accordingly (this improves clarity and also makes parsing easier)

Test coverage

• Adds transcript tests for the MCP server
