The MCP catalog helps you add third-party MCP services to your organization without assembling every connection detail from scratch. In Tools and MCP, open the MCP Servers tab, then choose Browse Catalog (as opposed to My Servers, which lists what you already configured).

Each card summarizes a service (description, category tags such as France or Legal, and a link to the provider’s documentation). Use + Add to start adding a catalog entry to your organization. When a service is already connected, the card can show Configured instead.

Open access and API keys

Catalog entries fall into two broad patterns:

  • Open or public access - Some endpoints do not require you to register with the third party or paste a secret; the product can mark them as ready to use once added (for example open government data sources such as datagouv).

  • Provider account and key - Others expect you to sign up on the provider’s site, generate an API token, and paste it in the admin console. The token is stored securely and sent according to the service (often as a Bearer token).

Always check the provider’s documentation linked from the card for pricing, quotas, and terms.

Add to organization

When you add a service that needs credentials, a dialog such as Add to Organization collects the server label, Server URL (often prefilled from the catalog), Authentication (for example Bearer Token), and the API Token field. Use Test & Add to verify the connection before saving.

After a successful add, the server appears under My Servers and follows the same lifecycle as any other MCP server (tool selection, active/inactive, edits). See MCP servers for connection options and tool filtering.
