This repository is the public metadata + install kit for marketplace listings (official MCP Registry, Grok Build plugins, open directories). The server itself is hosted at passfa.st — there is no local stdio binary here.

Auth

Code

Authorization: Bearer sk_live_YOUR_SECRET_KEY
X-App-Id: YOUR_APP_ID   # optional for single-app orgs

Secret keys only (sk_live_). Publishable pk_live_ keys are rejected.
No OAuth, no PassFast agent account — the MCP client is the agent.
Member/invite tools need a user JWT and are out of scope for key-auth MCP v1.

Install

Cursor

Copy cursor/mcp.json into ~/.cursor/mcp.json or project .cursor/mcp.json, then replace the placeholders.

Claude (HTTP)
