Inspect, debug, and replay captured webhooks to localhost directly from your AI agent via Pipehero.
Do not connect
The transport layer (TLS) is invalid or missing, so traffic to this server cannot be trusted end to end.

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 pipehero MCP server exposes 7 tools, focused primarily on communication capabilities. Its published description reads: "Inspect, debug, and replay captured webhooks to localhost directly from your AI agent via Pipehero". It communicates over Streamable HTTP using the 2026-07-28 protocol revision, and does not require authorization to connect. MCPGrade currently rates pipehero T — its TLS configuration is invalid or missing, so the transport itself cannot be trusted. Its most notable findings include "Cross-tool shadowing" and "Invalid or expired TLS certificate". 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 pipehero's advertised tools, transport security, and authorization posture before connecting an autonomous agent or sharing sensitive context with it.
Add pipehero to an MCP client using the endpoint below. Review the grade and findings above before granting an autonomous agent access.

https://mcp.pipehero.app/mcpStreamable HTTP transport. This is the MCP endpoint, not a website — paste it into your MCP client server list rather than a browser.
Captured passively during the read-only scan. Click any value to find servers that match it.
The tools this server advertises via tools/list — names, purposes, and the parameters each accepts, exactly as enumerated read-only.
List the user's Pipehero tunnels and whether each is currently online.
List recent webhooks/requests captured for a tunnel. Returns id, method, path, status and bodies.
Get the full request and response (headers + body) of one captured webhook by id.
Replay a captured webhook to the user's localhost (the tunnel CLI must be running).
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.
