# Phantom Connect SDK MCP server

> Get accurate Phantom developer guidance in your AI coding assistant

## Overview

The Phantom Connect SDK MCP (Model Context Protocol) server connects AI coding assistants like [Cursor](https://cursor.com/), [Claude](https://claude.ai/), and [VS Code](https://code.visualstudio.com/) to Phantom developer documentation. Your AI assistant can answer questions and generate code with accurate, up-to-date context.

<Info>
  Looking for the MCP server that gives AI agents direct access to Phantom wallet operations like signing transactions and transferring tokens? See the [Phantom MCP server](/phantom-mcp-server) documentation.

<Info>
  MCP is an open protocol that allows AI applications to securely connect to external data sources and tools. Learn more about MCP at [modelcontextprotocol.io](https://modelcontextprotocol.io/).

## Setup guides

<Tabs>
  <Tab title="Cursor">
    ### Option 1: Cursor plugin (recommended)

    Install the [Phantom Cursor plugin](https://cursor.com/marketplace/phantom) for the best experience. It includes this MCP server plus subagents, skills, and rules for building with Phantom. See the [Cursor plugin documentation](/resources/cursor-plugin) for details.

    ### Option 2: Quick install

    Use the contextual menu at the top of this page and select **Connect to Cursor** to automatically install the MCP server.

    ### Option 3: Manual setup

    <Steps>
      <Step title="Open MCP settings">
        Use `Cmd + Shift + P` (Mac) or `Ctrl + Shift + P` (Windows/Linux) to open the command palette, then search for **Open MCP settings**.
      </Step>

      <Step title="Configure the Phantom Connect SDK MCP server">
        Add the following to your `mcp.json` file:

        ```json theme={null}
        {
          "mcpServers": {
            "phantom-docs": {
              "type": "sse",
              "url": "https://docs.phantom.com/mcp"
            }
          }
        }
        ```

        If you already have other MCP servers configured, add `phantom-docs` to your existing `mcpServers` object.
      </Step>

      <Step title="Verify the connection">
        In Cursor's chat, ask "What tools do you have available?"—Cursor should show the Phantom Connect SDK MCP server as an available tool.
      </Step>
    </Steps>

    claude mcp add --transport http phantom-docs https://docs.phantom.com/mcp
    ```

    ### Verify the installation

    Check that the server was added successfully:

    ```bash theme={null}
    claude mcp list
    ```

## Usage

Once configured, your AI assistant can search Phantom documentation when you ask questions about:

* Phantom SDK integration (React, React Native, Browser)
* Wallet connection and authentication flows
* Transaction signing and sending
* Message signing for authentication
* Multi-chain support (Solana, Ethereum, Bitcoin, Sui, and more)
* Phantom Portal setup and configuration
* Best practices and troubleshooting

### Example prompts

Try asking your AI assistant:

* "How do I set up Phantom Connect in a React app?"
* "Show me how to sign a message with the Phantom Browser SDK"
* "What's the process for verifying a domain in Phantom Portal?"
* "How do I send a Solana transaction using Phantom?"

The AI will search Phantom documentation and respond with accurate answers and code examples.

## Troubleshooting

<AccordionGroup>
  <Accordion title="Server shows as disconnected in Cursor">
    * Make sure you include `"type": "sse"` in your Cursor configuration
    * Verify you have an active internet connection
    * Check that the URL is exactly `https://docs.phantom.com/mcp`
    * Try removing and re-adding the server
    * Restart Cursor completely
  </Accordion>

  <Accordion title="AI doesn't use the documentation">
    * Make sure the MCP server shows a green status indicator
    * Try explicitly asking about Phantom (e.g., "Using Phantom docs, how do I...")
    * Verify the server is enabled in your settings
    * In Cursor, ask "What tools do you have available?" to verify the connection
  </Accordion>

  <Accordion title="Configuration file not found">
    * **Cursor**: The `mcp.json` file is located at `~/.cursor/mcp.json` (Mac/Linux) or `%APPDATA%\Cursor\mcp.json` (Windows)
    * **VS Code**: Create `.vscode/mcp.json` in your project directory
    * If the file doesn't exist, create it with the configuration shown above
  </Accordion>

  <Accordion title="Claude connector not working">
    * Make sure you're using the correct URL: `https://docs.phantom.com/mcp`
    * Try removing and re-adding the connector
    * Check the [Claude Connectors page](https://claude.ai/settings/connectors) to verify the connector is added
  </Accordion>
