See through your agent's eyes. Visualize legacy code, inspect complex flows, understand everything.

• Visualize Anything: Use your coding agent to generate on-demand architecture, code, and process diagrams to view your code from different perspectives.
• Vibe Checks: AI-generated code can accumulate unused and redundant constructs. Use visualizations to spot areas that need cleanup.
• Local Processing: Diagrams are never sent to the cloud. Everything stays between you, your agent, and your agent's LLM provider(s).
• Export & Share: Export any diagram as a vector image.

Node.js v20.0.0 or higher.

claude mcp add mindpilot -- npx @mindpilot/mcp@latest

Under Settings > Cursor Settings > MCP > Click Add new global MCP server and configure mindpilot in the mcpServers object.

{
  "mcpServers": {
    "mindpilot": {
      "command": "npx",
      "args": ["@mindpilot/mcp@latest"]
    }
  }
}

Follow the instructions here for enabling MCPs in VS Code: https://code.visualstudio.com/docs/copilot/chat/mcp-servers

Go to Settings > Features > MCP, then click Edit in settings json

Then add mindpilot to your MCP configuration:

{
  "mcp": {
    "servers": {
      "mindpilot": {
        "type": "stdio",
        "command": "npx",
        "args": ["@mindpilot/mcp@latest"]
      }
    }
  }
}

Under Settings > Windsurf Settings > Manage Plugins, click view raw config and configure mindpilot in the mcpServers object:

{
  "mcpServers": {
    "mindpilot": {
      "command": "npx",
      "args": ["@mindpilot/mcp@latest"]
    }
  }
}

In the AI Thread panel click on the three dots ..., then click Add Custom Server...

In the Command to run MCPserver field enter npx @mindpilot/mcp@latest and click Add Server.

• Port: The server defaults to port 4000 but can be configured using the --port command line switch.
• Data Path: By default, diagrams are saved to ~/.mindpilot/data/. You can specify a custom location using the --data-path command line switch.

Mindpilot intelligently handles multiple AI assistants running simultaneously. When you have multiple Claude Desktop windows or IDE instances open:

• The first mcp client to use Mindpilot starts a shared web server
• Additional assistants automatically connect to the existing server
• All assistants share the same diagram history and web interface
• The server will automatically shuts down a minute after the last MCP clinet disconnects

This means you can work with multiple MCP hosts at once without port conflicts, and they'll all contribute to the same collection of diagrams.

Mindpilot MCP collects anonymous usage data to help us understand how the product is being used and improve the user experience.

If you prefer not to share anonymous usage data, you can disable analytics by adding the --disable-analytics flag to your MCP configuration:

Claude Code:

claude mcp add mindpilot -- npx @mindpilot/mcp@latest --disable-analytics

Other IDEs: Add "--disable-analytics" to the args array in your configuration:

{
  "command": "npx",
  "args": ["@mindpilot/mcp@latest", "--disable-analytics"]
}

After configuring the MCP in your coding agent you can make requests like "create a diagram about x" and it should use the MCP server to render Mermaid diagrams for you in a browser connected to the MCP server.

You can optionally update your agent's rules file to give specific instructions about when to use mindpilot-mcp.

• "Show me the state machine for WebSocket connection logic"
• "Create a C4 context diagram of this project's architecture."
• "Show me the OAuth flow as a sequence diagram"

Frontier LLMs are well trained to generate valid Mermaid syntax. The MCP is designed to accept Mermaid syntax and render diagrams in a web app running on http://localhost:4000 (default port).

If you use port 4000 for another service you can configure the MCP to use a different port.

Claude Code example: claude mcp add mindpilot -- npx @mindpilot/mcp@latest --port 5555

To save diagrams to a custom location (e.g., for syncing with cloud storage):

Claude Code example: claude mcp add mindpilot -- npx @mindpilot/mcp@latest --data-path /path/to/custom/location

Other IDEs:

{
  "command": "npx",
  "args": ["@mindpilot/mcp@latest", "--data-path", "/path/to/custom/location"]
}

If you use asdf as a version manager and have trouble getting MCPs to work (not just mindpilot), you may need to set a "global" nodejs version from your home directory.

cd
asdf set nodejs x.x.x

Configure the MCP in your coding agent (using claude in this example)

claude mcp add mindpilot -- npx tsx <path to...>/src/server/server.ts

Run claude with the --debug flag if you need to see MCP errors

Start the development client (Vite) to get hot module reloading while developing.

npm run dev
