What the code does

We read the source, 22 h ago · rules 3dff92dd89df

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.

File ships in the package but is absent from the source [пакет] bin/callimachus-mcp.mjs:1

этот файл ставится пользователю, но в репозитории его нет

Builds a file path from a variable apps/vscode/src/cal.ts:41

  const c: string[] = [path.join(home, ".local", "bin", exe)];

Runs an external command packages/callimachus-mcp/bin/callimachus-mcp.mjs:18, [пакет] bin/callimachus-mcp.mjs:18

  const child = spawn(bin, process.argv.slice(2), { stdio: "inherit" });

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.

Callimachus — questions

Answers built from our own checks of this server.

Why is there no uptime for Callimachus?

Callimachus 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 callimachus-mcp was installed 94 times last week.

How do I connect Callimachus?

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 callimachus-mcp straight from npm; nothing to host, nothing to sign up for.

How many people use Callimachus?

The npm package callimachus-mcp was installed 94 times in the last week. Week over week that is +29%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Callimachus open source?

Yes — it is published under the AGPL-3.0 licence, written in Rust and 39 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.
