MCP Plugins
Connect external tools to Claude via the Model Context Protocol.
MCP Plugins
Model Context Protocol (MCP) is an open standard for connecting AI assistants to external tools. CodePilot has a built-in MCP client that supports connecting to any MCP server to extend Claude's capabilities.
What is MCP?
MCP servers provide Claude with additional tools, such as:
- File System — Read/write files, search directories
- Database — Query databases directly
- API Integrations — Connect to external services like GitHub, Jira, Slack
- Development Tools — Run tests, lint code, manage dependencies
- Custom Tools — Build any tool you need
Managing MCP Servers
Click MCP in the sidebar to open the management page. The page provides two views:
List View
Displays all configured MCP servers as cards, each showing:
- Server name
- Connection status (Connected / Disconnected / Error)
- List of tools provided
JSON Editor
Directly edit the MCP configuration JSON file — useful for bulk configuration or importing settings from other tools.
Adding an MCP Server
- Click Add Server on the MCP page
- Fill in the configuration:
- Name — A descriptive name for the server
- Transport Type — Select the connection method:
- stdio — Local process communicating via standard input/output (most common)
- SSE — Connect to a remote server via Server-Sent Events
- HTTP (Streamable) — Connect via HTTP streaming
- Command (stdio type) — The command to start the server, e.g.,
npx @modelcontextprotocol/server-filesystem - Arguments — Command-line arguments
- URL (SSE / HTTP type) — The remote server address
- Environment Variables — Environment variables the server needs (API keys, etc.)
- After saving, the server will start automatically
Using MCP Tools
Once an MCP server is connected, its tools automatically become available to Claude. Claude will call these tools as needed while processing your requests.
You can view the specific tool list for each server on the MCP page.
Popular MCP Servers
| Server | Purpose |
|---|---|
@modelcontextprotocol/server-filesystem | File system access |
@modelcontextprotocol/server-github | GitHub integration |
@modelcontextprotocol/server-slack | Slack integration |
@anthropic-ai/mcp-server-fetch | Web fetching |
More MCP servers can be found in the official MCP repository and the community.
Troubleshooting
- Server won't connect — Check that the command is correct and the required npm package is installed
- Tools not appearing — Try disconnecting and reconnecting the server
- Permission errors — Ensure the MCP server has access to the required resources
- SSE/HTTP connection fails — Check that the URL is correct and the server is running
