Connect once. Use Loxihart Signal anywhere.

Plug your unique Loxihart Signal endpoint URL into Claude, ChatGPT, Gemini, Grok, Cursor, or any custom webhook bot. AI assistants connect over Streamable HTTP MCP; chat and automation bots post JSON straight to the REST endpoint.

Copy your unique endpoint URL

Use the Primary MCP URL for MCP-compatible AI assistants, the OpenAI MCP URL for ChatGPT, or the REST URL for webhook and chat bots.
