What is feishu-user-plugin?

A Claude Code plugin that connects Feishu, also called Lark, to an agent through an MCP server and command-line tool. Feishu is a workplace app for messaging, documents, tables, calendars, tasks, and related work data.

Sending and reading messages, managing documents, tables, wiki pages, files, OKRs, calendars, and tasks, including creating and updating records.

It lets an agent work with Feishu information and actions from one integration instead of separate connections for each service. It supports multiple user profiles and authentication methods.

Security

Grade A, and why

feishu-user-plugin scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
