Claude

Claude.ai and Claude Desktop support Client ID Metadata Document (CIMD) registration, so CARTO can recognize them automatically. No OAuth client needs to be created or registered. Simply provide Claude with the CARTO MCP Server URL and sign in.

Both Claude.ai and Claude Desktop can also render CARTO maps inline in the conversation, providing a richer experience when working with CARTO maps and spatial data.

This zero-configuration OAuth flow is enabled by CIMD support. Other MCP clients may use different OAuth registration flows See Connecting with OAuth for how CARTO handles clients that lack it.

For the terminal coding agent, see Claude Code.

Claude connects over OAuth, so the agent gets the full tool surface — creating and editing maps, authoring Workflows, and admin. If your org uses SSO, use the SSO login URL from the Workspace instead.
