Codex plugin - Crustdata Docs

The Crustdata plugin for Codex bundles the MCP server and ready-to-run skills into a single install. Two commands add the data tools (800M+ people profiles and 200M+ companies) and the skills.

This installs Crustdata in Codex, the coding agent. To use Crustdata in ChatGPT itself, add the ChatGPT connector instead.

Two commands to install. The data tools and the skills come together, no config file to hand-write.
Sign in once. A browser sign-in, no API key to paste.
The same endpoint everywhere. The plugin registers https://install.crustdata.com/mcp.

What’s included

MCP data tools

The full Crustdata MCP server: search and enrich companies, people, and jobs, and read social and web content, in plain English.

Skills

Ready-made workflows for prospecting, account research, outreach, meeting prep, and candidate sourcing.

One sign-in

The data tools and the skills share a single sign-in. No API key to copy or paste.

Credit costs vary by request and plan. See Pricing for per-request credit costs and Rate limits for limits.

Troubleshooting

MCP tool call requires approval. Non-interactive runs (codex exec) decline tool calls that need approval. Run Codex interactively and approve the call.
Not inside a trusted directory. codex exec expects a git repository. Run it in your project, or pass --skip-git-repo-check.
The sign-in does not stick. Run codex mcp login crustdata again. Judge it by whether a request works, not by the Auth column.
