Serverless edge gateway that discovers, verifies, and routes calls across thousands of hosted tool servers.

Scanned 1 month 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 metamesh-uga-gateway MCP server exposes 16 tools, focused primarily on general-purpose capabilities. Its published description reads: "Serverless edge gateway that discovers, verifies, and routes calls across thousands of hosted tool servers". It communicates over Streamable HTTP using the 2026-07-28 protocol revision, and does not require authorization to connect. MCPGrade currently rates metamesh-uga-gateway F — a critical issue was found and the server should not be connected as-is. Its most notable findings include "Cross-tool shadowing" 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 metamesh-uga-gateway's advertised tools, transport security, and authorization posture before connecting an autonomous agent or sharing sensitive context with it.
Add metamesh-uga-gateway to an MCP client using the endpoint below. Review the grade and findings above before granting an autonomous agent access.

Compact snapshot of the MetaMesh gateway: active tool count, top categories, payment/billing status, last discovery. Best first call for context.
Search the catalog of 13k+ MCP tools by keyword. Returns concise matches (name, category, description). Use this instead of listing all tools.
Detailed info for a specific catalog tool: description, category, trust/security score, state, source.
Usage analytics: total tools, calls, success rate and recent error counts. Read-only.
Control/observability: status of the registry discovery engine (active tools, last run, pages fetched).
Sorted worst-first. Each finding shows its severity, what it means, its OWASP MCP Top-10 mapping, and a recommended fix — the check id links to the exact methodology row that produced it.
