MCP Server

The Model Context Protocol (MCP) is an open standard that lets AI agents use external tools. Contrabxnd's MCP server exposes market intelligence, on-chain node queries, Lightning, and pricing as callable tools over a single authenticated endpoint.

Endpoint

https://www.contrabxnd.io/api/mcp

Authentication

Every request needs an API key in the Authorization header as a bearer token. Generate one on the MCP page (keys are prefixed cbx_, sha-256 hashed at rest, and revocable).

Authorization: Bearer cbx_YOUR_KEY
