What the probe found

blockerThis is a web page, not an MCP endpoint

The URL served HTML rather than JSON-RPC (POST returned 403) — almost certainly the documentation page, not the endpoint. It names: https://frtracker.app/mcp?__cf_chl_tk=TwA0UtcYGQ7R_K.RYLvtMERLUgbqbC6qB_Yq3XTM5ec-1792347064-1.0.1.1-IBqaI1gWM29evWUkHlMN95Q3s_FMUh9eSMUrga1Arow, https://frtracker.app/mcp?__cf_chl_f_tk=TwA0UtcYGQ7R_K.RYLvtMERLUgbqbC6qB_Yq3XTM5ec-1792347064-1.0.1.1-IBqaI1gWM29evWUkHlMN95Q3s_FMUh9eSMUrga1Arow, https://frtracker.app/mcp?__cf_chl_rt_tk=TwA0UtcYGQ7R_K.RYLvtMERLUgbqbC6qB_Yq3XTM5ec-1792347064-1.0.1.1-IBqaI1gWM29evWUkHlMN95Q3s_FMUh9eSMUrga1Arow.
