The Arc Model Context Protocol (MCP) server gives AI tools direct access to Arc documentation so they can search for relevant content and retrieve full pages during conversations. It is hosted at https://docs.arc.network/mcp and requires no authentication. The server exposes two tools:
  • Search — finds relevant documentation snippets based on a query.
  • Get page — retrieves the full content of a specific documentation page.
For a machine-readable index of all documentation pages, see the llms.txt file.

​
Claude Code

Run the following command to add the Arc MCP server: 
claude mcp add --transport http arc-docs https://docs.arc.network/mcp
Claude Code automatically discovers the server’s tools on the next conversation.

​
Claude Desktop

  1. Open Settings and navigate to Connectors.
  2. Select Add custom connector.
  3. Enter Arc Docs as the name and https://docs.arc.network/mcp as the URL.
  4. During a chat, use the attachments button to select the Arc Docs connector.

​
Cursor

Add the following to your mcp.json file (accessible via Cursor Settings > MCP): 
{
  "mcpServers": {
    "arc-docs": {
      "url": "https://docs.arc.network/mcp"
    }
  }
}

​
VS Code (Copilot)

Create or update .vscode/mcp.json in your project root: 
{
  "servers": {
    "arc-docs": {
      "type": "http",
      "url": "https://docs.arc.network/mcp"
    }
  }
}

​
Windsurf

Add the following to your Windsurf MCP configuration: 
{
  "mcpServers": {
    "arc-docs": {
      "serverUrl": "https://docs.arc.network/mcp"
    }
  }
}

​
Other MCP clients

Any MCP-compatible client can connect using the HTTP transport at https://docs.arc.network/mcp. Most clients require only the server URL and transport type (http). Refer to your client’s documentation for the exact configuration format.

​
Verify the connection

After adding the server, confirm the connection by asking your AI tool a question about Arc, such as “What smart contract standards does Arc support?” The tool should return content sourced from Arc documentation. If it does not:
  • Check the URL — confirm it is exactly https://docs.arc.network/mcp with no trailing path.
  • Check network access — the server must be reachable over HTTPS from your machine.
  • Restart the client — some tools only detect new MCP servers after a restart or new session.
