# MCP

> Add, import, and manage Model Context Protocol servers so the model can use external tools.

MCP (Model Context Protocol) lets the model call external tools and data sources safely, such as fetching a web page, looking up docs, or accessing a database.

In CC GUI, open **Settings → MCP servers**. Claude and Codex are shown separately, each with its own server list and tool set.

## Add a server

Click **Add**. There are three paths.

### Manual config

Paste MCP Servers JSON. Prefer `npx` or `uvx` to start a local process.

Two transports:

| Type       | How it connects                            | Example                                      |
| ---------- | ------------------------------------------ | -------------------------------------------- |
| stdio      | Standard input / output of a local process | `npx -y @modelcontextprotocol/server-memory` |
| HTTP / SSE | Remote URL                                 | Your own MCP service URL                     |

Scope:

* **Global**: written to `~/.claude.json`, available to all projects
* **This project only**: applies only to the current project

<Warning>
  The config will run commands on your computer. Check the source, arguments, and environment variables before you add it.
</Warning>

### Add from the MCP marketplace

The marketplace lists installable servers by registry. You can search by name, publisher, or tag.

* **Installable**: can generate a config directly
* **Browse only**: metadata only. Add it yourself from the repo docs

### Import from GitHub Copilot

Paste Copilot MCP JSON. The root key is `servers`. Preview first, then import. Duplicate names are renamed automatically.

## Status and tools

Each server card shows connected, connecting, needs auth, or connection failed.

Open a card to:

* Enable / disable
* View the tool list
* Open connection logs
* Edit or delete

## Use it in chat

After a server is enabled and connected, Claude Code picks tools for the task automatically. You can also run `/mcp` to inspect status.

Permissions still follow the current run mode. In default mode, an MCP tool may still ask first. See [Run modes and permissions](/en/jetbrains/chat/modes).
