First Street MCP Server is one of 7 APIs that [First Street](https://apis.io/providers/first-street/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include MCP, Agents, Climate, and Risk. The published artifact set on APIs.io includes API documentation.

Hosted, remote Model Context Protocol server exposing the Climate Risk API to agents over Streamable HTTP. Ten tools with real JSON Schema inputs — property lookup by address, coordinate or Place ID, building discovery inside a polygon, adaptation cost-benefit, locality macroeconomics, metadata, and an arbitrary GraphQL escape hatch. Authenticated with the same API key as the rest of the surface; tools/list is answerable anonymously.
