Response contract ↗

MCP for agents

Add the hosted server in Claude Code:

claude mcp add --transport http pointmoon https://pointmoon.ai/api/mcp

For other clients, use this Streamable HTTP URL:

https://pointmoon.ai/api/mcp

Then ask your agent: “Use Pointmoon to read the conditions at 51.508, -0.128. Tell me the sources and what is missing.”
