# Developer Portal MCP server

> Access Chainstack documentation, API references, and blockchain development guides through the Developer Portal MCP server for AI-assisted coding.

<Warning>
  **Deprecated.** Documentation search is now available through the unified [Chainstack MCP server](/docs/chainstack-mcp-server) at `https://mcp.chainstack.com/mcp`. The Developer Portal MCP server below will continue to work but is no longer the recommended integration.
</Warning>

The **Developer Portal MCP server** is integrated with Chainstack's documentation platform powered by Mintlify. This MCP server provides AI models with comprehensive access to Chainstack's blockchain development resources, documentation, and guides.

This is a streamable HTTP MCP server, and not an SSE connection. Streamable HTTP is the latest MCP standard overtaking SSE.

## Installation

### Cursor

Just click the **Connect to Cursor** button at the top of any page to automatically install the MCP server in Cursor.

### VS Code

Just click the **Connect to VS Code** button at the top of any page to automatically install the MCP server in VS Code.

### Claude Code

To add the Chainstack MCP server to Claude Code, use the following command:

```
claude mcp add --transport http Chainstack-Developer-Portal https://docs.chainstack.com/mcp
```

The MCP server will be automatically configured and available in your Claude Code conversations.

### Windsurf

To add the Chainstack MCP server to Windsurf:

1. Open Windsurf Settings by pressing `Cmd+Shift+P` (Mac) or `Ctrl+Shift+P` (Windows/Linux)
2. Type "Open Windsurf Settings" and select it
3. Navigate to the **Cascade** section
4. Click **"Add Custom Server +"** or edit the configuration file directly

Add the following configuration to `~/.codeium/windsurf/mcp_config.json`:

```json theme={"system"}
{
  "mcpServers": {
    "chainstack-developer-portal": {
      "serverUrl": "https://docs.chainstack.com/mcp"
    }
  }
}
```

5. Save the configuration and click **"Refresh Servers"** in the Cascade settings
6. Verify the integration by clicking the Hammer Icon in the Cascade toolbar — the Chainstack documentation search tool should appear

### Codex

To add the Chainstack MCP server to OpenAI Codex, first set a dummy environment variable:

```bash theme={"system"}
export PASTE_THIS_OR_ANY_DUMMY_TOKEN=paste_this_or_any_dummy_token
```

Then add the MCP server:

```bash theme={"system"}
codex mcp add devportal --url https://docs.chainstack.com/mcp --bearer-token-env-var "PASTE_THIS_OR_ANY_DUMMY_TOKEN"
```

<Note>
  The Developer Portal MCP server is public and requires no authentication. The dummy token is a workaround for a [known Codex OAuth issue](https://github.com/openai/codex/issues/5588).
</Note>

## Manual configuration

For other AI tools that support streamable HTTP MCP, use the following URL:

```
https://docs.chainstack.com/mcp
```

This URL provides access to the complete Chainstack documentation and development resources through the Model Context Protocol.

Again, do note that this is a streamable HTTP MCP connection, and not an SSE connection. Streamable HTTP is the latest MCP standard overtaking SSE.
