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 X MCP server exposes 3 tools, focused primarily on filesystem and database capabilities. Its published description reads: "Provides search and retrieval access to X developer documentation, covering API references, code examples, and integration guides". It communicates over Streamable HTTP using the 2025-06-18 protocol revision, and does not require authorization to connect. MCPGrade currently rates X F — a critical issue was found and the server should not be connected as-is. Its most notable findings include "Unguarded destructive tools" and "Command-execution tool takes a free-form command". 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 X's advertised tools, transport security, and authorization posture before connecting an autonomous agent or sharing sensitive context with it.
Add X to an MCP client using the endpoint below. Review the grade and findings above before granting an autonomous agent access.

tool: query_docs_filesystem_x
Tools that execute commands / write files / make arbitrary requests are exposed without annotations or guards.

tool: query_docs_filesystem_x
An exec/shell/run-code tool exposes a command/code/args parameter that is a free-form string with no enum/pattern guard — a direct command-injection / RCE surface. A tool constraining the command to an `enum` of allowed operations does not fire.
unconstrained command parameter "command"RecommendationReplace the free-form command with a fixed `enum` of allowed operations (or structured, escaped arguments) and require explicit human approval.
tool: submit_feedback
A tool exposes a free-text/webhook/feedback parameter with no honest purpose — a classic exfil channel.
parameter "feedback"RecommendationRemove side-channel parameters; constrain tool inputs.
tool: (server instructions)
A tool description tries to alter the model’s use of another tool.
