Jacobian MCP Server

English · 简体中文 Jacobian An executable mathematical vocabulary for agents: discover one typed operation, run it, and compose its result. It runs locally over stdio via the published package.

People connecting automation tools to Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

01 · Install Jacobian

Claude Code

claude mcp add morluto-jacobian -- npx -y jacobian

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "morluto-jacobian": {
      "command": "npx",
      "args": [
        "-y",
        "jacobian"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

repo age created 2026-07-23 - young repo, little track record yet

license MIT - declared in the repository

npm package jacobian - unscoped; check the name against the project README before installing

registry namespace io.github.morluto is GitHub-verified and matches the repo owner

06 · Jacobian FAQ

What is Jacobian?

English · 简体中文 Jacobian An executable mathematical vocabulary for agents: discover one typed operation, run it, and compose its result. It runs locally over stdio via the published package.

Is Jacobian still maintained?

Yes - as of 2026-08-25, its last commit was 2026-08-25 and it shipped 10+ releases in the last 90 days. We re-verify nightly.

How do I install Jacobian?

Run `npx -y jacobian`. You can also paste the ready-made client config above.

Does Jacobian run locally?

Yes - it's a stdio server: it runs on your machine (via npx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
