Inspects webhook health, investigates delivery failures, configures sources, and replays missed events for Relin's webhook reliability platform.
Review before connecting
The findings on this server are worth reviewing before you connect an agent to it.
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 relin-mcp MCP server exposes 52 tools, focused primarily on general-purpose capabilities. Its published description reads: "Inspects webhook health, investigates delivery failures, configures sources, and replays missed events for Relin's webhook reliability platform". It communicates over Streamable HTTP using the 2025-06-18 protocol revision, and does not require authorization to connect. MCPGrade currently rates relin-mcp 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 relin-mcp's advertised tools, transport security, and authorization posture before connecting an autonomous agent or sharing sensitive context with it.
Add relin-mcp to an MCP client using the endpoint below. Review the grade and findings above before granting an autonomous agent access.
MCP endpoint

The tools this server advertises via tools/list — names, purposes, and the parameters each accepts, exactly as enumerated read-only.
Explain what Relin does and how agents should use it for webhook intake, delivery, replay, and anomaly review.
List the vendor webhook shapes Relin understands for event identity, ordering, and gap checks.
Return concise setup guidance for connecting a webhook source and destination.
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.
