Stackcrawler MCP Server

Connect

Stackcrawler provides a remote MCP server over Streamable HTTP. Add the endpoint to your MCP client and authenticate with a Stackcrawler API key.

Server endpoint

Use this URL as the remote MCP server address.

https://api.stackcrawler.com/mcp

Create or manage an API key in API Settings. A key is shown only once when it is generated, so store it securely.

Cursor

Add this entry to your Cursor MCP configuration. Replace the placeholder with your API key and do not commit the key to a shared configuration file.
