Developer Portal MCP server

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

Deprecated. Documentation search is now available through the unified 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.

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:

{
  "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:

export PASTE_THIS_OR_ANY_DUMMY_TOKEN=paste_this_or_any_dummy_token

Then add the MCP server:

codex mcp add devportal --url https://docs.chainstack.com/mcp --bearer-token-env-var "PASTE_THIS_OR_ANY_DUMMY_TOKEN"

The Developer Portal MCP server is public and requires no authentication. The dummy token is a workaround for a known Codex OAuth issue.

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.
