# MCP Registry

> Extend Cosmos Experts with external tools and services through Model Context Protocol (MCP) servers.

GitHub, Slack, and Linear are wired in directly. Everything else — databases, browser automation, third-party APIs — comes through MCP servers. The **MCP Registry** (under **Settings → Capabilities** in the Cosmos menu) is where you add them, including partner servers like Atlassian, Sentry, Stripe, and Figma.

## Managing MCP Configurations

### Updating or Removing

Manage your active servers directly from the **MCP Registry** page under **Settings → Capabilities**. From there you can update credentials, change scope, or delete configurations you no longer need.

### Pinning to an Expert

To make a registry server available inside a specific Expert, attach it from the **Tools** section of the Expert editor. The MCP server selector lists every server in the registry that the Expert can see — pick the ones you want and save. Pinned servers launch automatically with each session created from that Expert.
