Terra lets Claude find and call endpoints from Terra's curated catalog. It is a third-party community connector published by Superdesign; it is not an Anthropic product or a claim of Anthropic verification.
While the directory listing is under review, the same connector can be tested as a custom
connector using https://useterra.app/mcp/v2/. Authentication uses OAuth with PKCE; do not paste a
Terra token or provider API key into Claude. The v2 in this URL identifies Terra's
restricted MCP transport; it is separate from connector release V1.
This version exposes the curated Terra catalog only. It cannot list or invoke team-owned tools, imported skills, arbitrary URLs, or arbitrary HTTP methods. It does not offer image, video, voice or music generation.
catalog_search and catalog_get find endpoints and show their input,
authentication, method, and price.catalog_call_read invokes only catalog entries declared as GET, HEAD, or OPTIONS.catalog_call_write invokes only catalog entries declared as POST, PUT, PATCH, or
DELETE. Claude controls its confirmation experience for these potentially mutating calls.balance reports the selected team's prepaid balance and daily usage.catalog_request records a request for a missing capability; it does not call a
provider or change provider data.Searching and inspecting the catalog is free. Before a metered call, Terra returns the endpoint's USD price. Calls served with Terra's platform credential debit the selected team's prepaid balance; calls using your own connected provider credential follow the provider's own billing as well. Your team's balance and daily cap are enforced before calls. See the current pricing page and the endpoint detail shown in Claude before proceeding.
Claude sends the chosen endpoint id and request inputs to Terra. Terra resolves the curated entry, applies the selected team's access rules and spending limits, injects the applicable credential server-side, and relays the request to that endpoint's provider. The provider response is returned to Claude without reshaping it. Provider credentials are never returned to Claude.
Terra records call metadata needed for metering, audit, reliability, and support. Provider request and response data necessarily pass through Terra to complete the call. Read the full privacy policy for retention, processors, and account-data rights.
Disconnect Terra from Claude in Settings → Connectors. To revoke the underlying authorization from Terra as well, sign in to Terra and remove the Claude grant from the connected-apps area, or ask support to revoke it. Disconnecting does not delete your Terra team, balance, provider connections, or audit history.
For setup, billing, privacy, security, or endpoint problems, visit Terra support or email jason@superdesign.dev. Include the endpoint id, approximate time, and the error text, but never send passwords, OAuth codes, tokens, or API keys.
