Does jCodeMunch MCP work with Claude Code?
Yes. jCodeMunch MCP passed every step of our test in Claude Code on Oct 22, 2026: it installed, connected, its tools were visible, and an agent used it to finish a real task.
Result
Steps
- install OK
- connect OK
- tools visible OK
- agent task: find definition OKsymbol lookup + one cross-file reference in a 2-file Python repo (git history has 1 commit, so git-only tools can answer via git_show)
