Crypto intelligence API gateway with x402 micropayments for real-time market data and financial analytics.
Review before connecting
The findings on this server are worth reviewing before you connect an agent to it.
Scanned 28 days ago Due for re-check
A server can change after it's graded. Re-run the automated scan to refresh this report.
This grade is deterministic and reproducible: the same server surface always yields the same grade under a given algorithm version. It is a real automated assessment computed by the MCPGrade engine from what the probe actually observed — not a fabricated or opinion score. It is not a manual human pentest, so it can miss context-specific risks.
Every signal below was measured directly by the automated probe. The grade is derived only from evidence like this — nothing is assumed.
The x402-alpha MCP server exposes 19 tools, focused primarily on general-purpose capabilities. Its published description reads: "Crypto intelligence API gateway with x402 micropayments for real-time market data and financial analytics". It communicates over Streamable HTTP using the 2025-06-18 protocol revision, and does not require authorization to connect. MCPGrade currently rates x402-alpha C- — the findings are worth reviewing before you connect an agent to it. Its most notable findings include "Data-exfiltration parameters" and "Data-exfiltration parameters". This report is a deterministic, reproducible automated assessment: the same observed surface always yields the same grade under a given algorithm version, and it is refreshed as new scans arrive and free to read — but it is not a substitute for a manual human security review. Always re-check x402-alpha's advertised tools, transport security, and authorization posture before connecting an autonomous agent or sharing sensitive context with it.
Add x402-alpha to an MCP client using the endpoint below. Review the grade and findings above before granting an autonomous agent access.
