Claude Code

Create or update a project .mcp.json file:

{
  "mcpServers": {
    "space-index": {
      "url": "https://mcp.spaceindex.io",
      "headers": { "Authorization": "Bearer ${SPACE_INDEX_API_KEY}" }
    }
  }
}

Read https://docs.spaceindex.io/llms.txt. Configure Space Index in Claude Code using the SPACE_INDEX_API_KEY environment variable. Never echo, log, or commit that value. List the available tools, then run a harmless search for "satellite" to confirm the connection.
