Free, open API and MCP server for The Urantia Book with 197 papers, full-text search, and entity browsing.
Do not connect
The assessed surface is high-risk. Remediate the findings before connecting.
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 Urantia Papers API MCP server exposes 19 tools, focused primarily on general-purpose capabilities. Its published description reads: "Free, open API and MCP server for The Urantia Book with 197 papers, full-text search, and entity browsing". It communicates over Streamable HTTP using the 2025-06-18 protocol revision, and does not require authorization to connect. MCPGrade currently rates Urantia Papers API D — the assessed surface is high-risk and should be remediated before use. 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 Urantia Papers API's advertised tools, transport security, and authorization posture before connecting an autonomous agent or sharing sensitive context with it.
Add Urantia Papers API to an MCP client using the endpoint below. Review the grade and findings above before granting an autonomous agent access.
