Feishu Channel for Claude Code

Connect a Feishu (飞书) bot to your Claude Code with an MCP server.

The MCP server logs into Feishu as a bot and provides tools to Claude to reply, react, or edit messages. When you message the bot, the server forwards the message to your Claude Code session.

Prerequisites

• Bun — the MCP server runs on Bun. Install with curl -fsSL https://bun.sh/install | bash.

Quick Setup

Default pairing flow for a single-user DM bot. See ACCESS.md for groups and multi-user setups.

1. Create a Feishu bot

Go to Feishu Open Platform → Create Custom App (创建自建应用). Give it a name (e.g. "ClaudeCode") and description.

1a. Copy credentials

Left menu → Credentials & Basic Info (凭证与基础信息):

• Copy App ID (cli_xxx) and App Secret — you'll need these in step 3.

1b. Add bot capability

Left menu → App Features (应用能力) → Bot (机器人):

• Toggle Enable Bot on. This makes the app appear as a bot users can DM.

1c. Configure permissions

Left menu → Permissions & Scopes (权限管理) → API Permissions:

Scope	Description	Required
im:message	Read messages	✅
im:message:send_as_bot	Send messages as bot	✅
im:resource	Download images/files from messages	✅ for photos
im:message.reactions:write	Add emoji reactions	Optional (for ackReaction)
im:chat:readonly	Read chat info	Optional

Search each scope name and click Activate (开通).

1d. Configure event subscriptions ⚠️

This step is critical. If you skip it or choose the wrong subscription method, the bot can send messages but cannot receive them.

Left menu → Event Subscriptions (事件与回调):

1. Subscription method (订阅方式) — select Long Connection (使用长连接 接收事件). This is the WebSocket mode, no public URL needed.
2. Click Add Event (添加事件) → search im.message.receive_v1 → add it. The full name is "Receive Messages v2.0" (接收消息 v2.0).

1e. Publish and approve

Left menu → App Release (版本管理与发布):

• Click Create Version (创建版本) → fill in version notes → Submit (提交发布).
• A Feishu admin in your organization needs to approve the release in the Admin Console. For personal/test tenants where you are the admin, it may auto-approve.

After any permission or event subscription change, you must publish a new version for it to take effect. This is easy to forget.

1f. Verify the bot is live

Open Feishu → search your bot name → you should see it as a contact. If not, check that the version is published and approved.

2. Install the plugin

These are Claude Code commands — run claude to start a session first.

First, register this repository as a plugin marketplace (only needed once):

claude plugin marketplace add V1ki/claude-feishu-plugin

Then install the plugin:

claude plugin install feishu@claude-feishu-plugin

Restart your session or run /reload-plugins. Check that /feishu:configure tab-completes.

3. Save credentials

/feishu:configure cli_xxx your_app_secret

Writes FEISHU_APP_ID=... and FEISHU_APP_SECRET=... to ~/.claude/channels/feishu/.env. You can also write that file by hand, or set the variables in your shell environment — shell takes precedence.

4. Launch with channel flag

Exit your session and start a new one:

claude --dangerously-load-development-channels plugin:feishu@claude-feishu-plugin

Note: --channels requires the plugin to be on Claude's approved channels allowlist, which is not yet available for third-party plugins. Use --dangerously-load-development-channels instead — it has the same functionality but skips the allowlist check.

5. Pair

DM your bot on Feishu — it replies with a 6-character pairing code. In your assistant session:

/feishu:access pair <code>

Your next DM reaches the assistant.

6. Lock it down

Pairing is for capturing IDs. Once you're in, switch to allowlist so strangers don't get pairing-code replies:

/feishu:access policy allowlist

Access control

See ACCESS.md for DM policies, groups, mention detection, delivery config, skill commands, and the access.json schema.

Quick reference: IDs are Feishu open_ids (e.g. ou_xxx). Default policy is pairing. ackReaction uses Feishu emoji types like THUMBSUP.
