MCP server exposing nine blockchain services — including hash anchoring, wallet screening, and token price lookup — via pay-per-call USDC micropayments.
Do not connect
A critical issue was found. Do not connect this server as-is.
Scanned 7 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 anchor-x402 MCP server exposes 18 tools, focused primarily on developer capabilities. Its published description reads: "MCP server exposing nine blockchain services — including hash anchoring, wallet screening, and token price lookup — via pay-per-call USDC micropayments". It communicates over Streamable HTTP using the 2025-06-18 protocol revision, and does not require authorization to connect. MCPGrade currently rates anchor-x402 F — a critical issue was found and the server should not be connected as-is. Its most notable findings include "Data-exfiltration parameters" and "No authorization on a public remote server". 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 anchor-x402's advertised tools, transport security, and authorization posture before connecting an autonomous agent or sharing sensitive context with it.
Add anchor-x402 to an MCP client using the endpoint below. Review the grade and findings above before granting an autonomous agent access.
