SiYuan Sisyphus MCP (yangtaihong59/siyuan-plugins-mcp-sisyphus) is an MCP server listed on the M8ven Trust Index. M8ven has not graded it: we have no way to read this server ourselves. No publisher has claimed this listing.
Enables AI agents to safely read, search, edit, and organize SiYuan notes, with git-like document timeline and notebook-level permissions.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
1/1 tools missing one or more hints — extension (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint). OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Shell command execution
8 child_process calls — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Secrets stay with their owner
1 secret/sensitive value flow into network calls (SIYUAN_API_URL → dynamic)
Audit where credentials are sent. A NOTION_TOKEN should only reach api.notion.com — never a third-party host.
Secrets not written to files
2 secret values written to files
Avoid persisting secrets to disk. Keep them in memory or your secret manager.
Secrets not logged
3 secret values sent to console.log
Redact or omit secret values from log output.
Dev dependencies
6 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
