Space Index documentation

Connect to Space Index through the API or the hosted MCP server. Both use the same read key.

Start by requesting access, then store the issued key in your local environment:

export SPACE_INDEX_API_KEY='replace-with-your-key'

Keep the key out of source control and saved prompts.

• API

  Use the API setup guide for direct HTTP integration. The API reference lists every available operation and response schema.

• Hosted MCP

  Use the hosted MCP guide to connect an agent or MCP client. Ready-to-copy configurations are in agent setup.

Machine-readable documentation

Agents can read llms.txt. API clients can use the OpenAPI document, and MCP clients can inspect the tool registry.
