Overview

This skill is a coherent Yuque document-reading MCP setup, but users should treat the Yuque session cookie as a sensitive account credential.

Install only if you are comfortable giving the MCP client and connected AI agent access to the Yuque documents reachable by your session. Store the session value carefully, avoid sharing MCP config files, use the least-privileged Yuque account practical, and rotate or remove the session if the config may have been exposed.

Missing User Warnings

Medium

• Confidence: 93% confidence
• Finding: The skill explicitly instructs users to retrieve a live `_yuque_session` cookie from browser developer tools and place it into MCP client configuration as an environment variable, but it does not clearly warn that this token is an authentication secret granting access to the user's Yuque content. In the context of an AI-connected MCP tool, exposing or mishandling this session can allow unauthorized document access, and users may not understand the credential sensitivity or persistence risks.
