codeindex MCP Server

local only

codeindex runs on your own machine — the client starts it, so there is no endpoint to ping. 91 installs a week from npm. Last commit 26 Sep 2026.

What the code does

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.

Runs a command on install [пакет] package.json:1
postinstall: node bin/postinstall.js
Builds a file path from a variable npm/build-mcpb.mjs:52, plugin/validate_skill.py:160
    copyFileSync(path.join(here, 'bin', f), path.join(stage, 'server', f));
const child = spawn(bin, args, { stdio: ['pipe', 'pipe', 'ignore'] });
In the project's build, not in the package

Found in continuous integration, deployment or infrastructure files, or in a neighbouring package of the same monorepo. None of this is installed when you add the server: it describes how the project is built and released. We list it because a leaked key in a build pipeline is still a real problem, but it is not something this server does on your machine.

Downloads and pipes straight to shell plugin/hooks/session-brief.sh:73
…ion. To drop it, install the binary and register it directly, then remove the plugin (its skills come with install.sh): curl -fsSL https://raw.githubusercontent.com/munhq/codeindex/main/install.sh | sh   -- do not run both, that is two servers and two writers on one snapshot."
          git config --global url."https://x-access-token:${{ secrets.GITHUB_TOKEN }}@github.com/".insteadOf "https://github.com/"
Runs an external command plugin/validate_skill.py:19
        self.p = subprocess.Popen(

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

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

run in your terminal
claude mcp add codeindex -- npx -y @munhq/codeindex

This one needs environment variables set before it will start: CODEINDEX_WORKSPACE (Directory to index. Defaults to the enclosing project root of wherever the client starts the server, which is the right answer for every editor and agent that launches it inside a repository. Set it only when the server runs somewhere other than the code.), CODEINDEX_NO_DAEMON (Set to 1 to keep the index inside this server process. By default every session on one repository shares a single background daemon that parses and watches the tree once, and each session is a thin relay onto it. Turn that off for a sandbox with no writable runtime directory.), CODEINDEX_DAEMON_IDLE_SECS (Seconds with no session attached before the shared daemon exits and returns its memory. Default 900. Set 0 to keep it resident.). The author declared them in the registry entry; get the values from the project itself.

codeindex — questions

Answers built from our own checks of this server.

Why is there no uptime for codeindex?
codeindex 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 npm package @munhq/codeindex was installed 91 times last week.
How do I connect codeindex?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls @munhq/codeindex straight from npm; nothing to host, nothing to sign up for.
How many people use codeindex?
The npm package @munhq/codeindex was installed 91 times in the last week. Week over week that is -13%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is codeindex open source?
Yes — it is published under the MIT licence, written in Zig and 3 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
