Tools

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)

No install — point any MCP client at the hosted endpoint:

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

Run from source

npm install
npm run build
node dist/index.js
