Install

Two ways to connect — a local stdio package, or the hosted remote endpoint.

Local (stdio, via npx)
npx opencrater-mcp
{
  "mcpServers": {
    "opencrater": {
      "command": "npx",
      "args": ["-y", "opencrater-mcp"]
    }
  }
}
Hosted (remote, Streamable HTTP)

{
  "mcpServers": {
    "opencrater": {
      "url": "https://opencrater.to/mcp"
    }
  }
}

Run from source

npm install
npm run build
node dist/index.js
