jCodeMunch MCP Server

local only

jCodeMunch MCP runs on your own machine — the client starts it, so there is no endpoint to ping. 20 997 installs a week from pypi. Last commit 2 Nov 2026.

Retrieves code by symbol via tree-sitter, so an agent reads the function it needs, not the file.

What the code does

A tool parameter reaches a dangerous call

A value the model can set ends up inside a file or shell call. That is not a flaw by itself — for a terminal server it is the job — but it is where things go wrong when it is not.

A tool parameter reaches a dangerous call get_changed_symbols.repo → src/jcodemunch_mcp/tools/get_changed_symbols.py:23, get_churn_rate.repo → src/jcodemunch_mcp/tools/get_churn_rate.py:26, get_file_risk.repo → src/jcodemunch_mcp/tools/get_file_risk.py:111 и ещё 6

Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

    if os.path.exists("/.dockerenv"):
Runs with shell=True .claude/hooks/pre_commit.py:169
        rc, out = run_budgeted(fmt, budget, shell=True)
Builds a database query by concatenation server/savings/post.php:76
    ON DUPLICATE KEY UPDATE total_tokens = total_tokens + VALUES(total_tokens)

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

That is not a flaw by itself — but it is where things go wrong when it is not the job. We re-read this code on every release. Watch it and you hear from us the day another one appears.

jCodeMunch MCP — questions

Answers built from our own checks of this server.

Why is there no uptime for jCodeMunch MCP?
jCodeMunch MCP runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the pypi package jcodemunch-mcp was installed 20 997 times last week.
How do I connect jCodeMunch MCP?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It runs locally, so the command pulls jcodemunch-mcp straight from pypi; nothing to host, nothing to sign up for.
How many people use jCodeMunch MCP?
The pypi package jcodemunch-mcp was installed 20 997 times in the last week. Week over week that is -32%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is jCodeMunch MCP open source?
We cannot say either way: written in Python and 2 829 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
