x402station MCP

An MCP adapter for x402station.io that acts as a pre-flight oracle for x402 endpoints. It allows agents to check endpoint safety before paying by exposing tools like preflight, forensics, and catalog decoys. The server independently probes endpoints to detect risks such as decoys, zombies, and price traps, providing evidence on uptime, latency, and settlement history.
