Utility Belt MCP

Utility Belt gives Codex and other MCP clients deterministic tools for common data work. It is stateless, has no external API dependencies, stores no submitted content, and requires no secrets.

Public website: https://wild-pulse-gm7zl.run.mcp-use.com

Production MCP endpoint: https://wild-pulse-gm7zl.run.mcp-use.com/mcp

Tools

Input text is limited to 2 MB, CSV data to 10,000 rows, and numeric input to 100,000 values.

Run locally

Requirements: Node.js 20 or newer.

npm install
npm run build
npm test
npm run start:stdio

For HTTP:

npm start

The MCP endpoint is http://localhost:3000/mcp; health is available at /health.

Codex plugin

The plugin manifest is in .codex-plugin/plugin.json. The included .mcp.json starts the compiled server over stdio using ${pluginRoot}.

Install dependencies and build before loading the plugin:

npm install
npm run build

Deploy

The included multi-stage Dockerfile is ready for a stateless cloud deployment. The server reads PORT, defaults to port 3000, and exposes Streamable HTTP at /mcp.

Manufact deployment requires this folder to be committed to a GitHub repository. Once connected, deploy with:

• Dockerfile: Dockerfile

• Port: 3000

• Health path: /health

• MCP path: /mcp

Privacy and security

• No input is persisted.

• No analytics or outbound network calls are implemented.

• All tools are read-only computations.

• SHA-1 and MD5 are compatibility hashes and are explicitly labeled as unsuitable for security.
