Core Concepts

Tool Naming

All MCP tools use the prefix mcp__lark-mcp__. Example:

mcp__lark-mcp__im.v1.message.create

Identity Types

Parameter	Value	Meaning
`useUAT`	`true`	Act as the logged-in user — resources are owned by the user, directly accessible
`useUAT`	`false` (default)	Act as the app/bot — resources owned by the application

Use useUAT: true for most interactive operations. Use false for background automation.

Standard Parameter Structure

path:      # URL path parameters (IDs, tokens)
params:    # Query string parameters (pagination, filters, id_type)
data:      # Request body payload
useUAT:    # true = user identity, false = app identity

`table_id`	`tblXXX`	Bitable table
`record_id`	`recXXX`	Bitable record
`open_id`	`ou_XXX`	User (OpenID)
`union_id`	`on_XXX`	User (UnionID, cross-app)
`chat_id`	`oc_XXX`	Group/DM chat
`message_id`	`om_XXX`	Individual message

12. Error Reference

Error Code	Meaning	Fix
`99991663`	Token expired	Re-login or refresh token
`99991664`	Invalid token	Check app credentials
`99991400`	Permission denied	Grant required scopes in developer console
`230001`	Bot not in chat	Add bot to the group first
`1254502`	Record not found	Verify record_id is correct
`1254520`	Field not found	Check field_name spelling exactly
`1300006`	Event not found	Verify event_id and calendar_id
`1100003`	Meeting not found	Meeting may have ended or reserve_id is wrong
`1100007`	Meeting not active	Use `reserve.get` to check status first
`1100032`	Not meeting host	Only host can perform this action
`1700001`	Minutes not found	Check minute_token format (`obcn...`)
`1700002`	Minutes not ready	Transcription still processing, retry later

Common Issues

"Tool not found": MCP server not running. Start with npx -y @larksuiteoapi/lark-mcp mcp -a <APP_ID> -s <APP_SECRET>
Resources inaccessible: Use useUAT: true — resources created by bot identity may not be visible to users
Permission error: In Feishu Open Platform console, enable the required permissions scopes (e.g. bitable:app, im:message, calendar:calendar, task:task:write)
message_id not found: Messages expire or may require im:message:send_as_bot scope
user_access_token expired: Run npx -y @larksuiteoapi/lark-mcp login to refresh (valid 2h, refreshable with offline_access scope)

13. Video Conferencing (vc.v1)

From the calendar event after the meeting (included in event details)
Format: obcn followed by alphanumeric characters (e.g. obcn6qGKMiZy0eNFSKl6e8XXXXX)

3. mcp__lark-mcp__minutes.v1.minuteStatistic.get
   → get participant list and speaking stats

4. mcp__lark-mcp__im.v1.message.create
   → send summary + participant stats as rich card to the meeting group chat

15. Enhanced Group Chat Workflows

This section covers advanced group chat scenarios beyond basic CRUD.

Find a Group by Name

1. mcp__lark-mcp__im.v1.chat.list → fetch all chats (paginate as needed)
2. Filter by name field client-side
   OR
   mcp__lark-mcp__im.v1.chat.search → params: query: "group name"

Send an @mention Message

# Tool: mcp__lark-mcp__im.v1.message.create
data:
  receive_id: "oc_xxx"
  msg_type: "text"
  content: '{"text":"<at user_id=\"ou_xxx\">John</at> please review this"}'
  # For @all:
  # content: '{"text":"<at user_id=\"all\">All</at> meeting in 5 minutes"}'
useUAT: true

          ]
        }
      ]
    }
useUAT: true

Create a Dedicated Project Group with Bot and Members

1. mcp__lark-mcp__contact.v3.user.batchGetId
   → resolve member emails → open_ids

2. mcp__lark-mcp__im.v1.chat.create
   → name: "Project X - Team"
   → user_id_list: [all open_ids]
   → chat_type: "private"

3. mcp__lark-mcp__im.v1.message.create
   → send a welcome card message introducing the project

Set a Group-Wide Announcement

1. mcp__lark-mcp__im.v1.chatAnnouncement.patch
   → insert new announcement text block at document tail
   → all members see the pinned announcement at top of chat

Monitor Group Messages (Event-driven)

Register the im.message.receive_v1 event in Feishu Open Platform to receive all messages sent in groups where the bot is present. OpenClaw's Feishu channel handles this automatically when configured — no polling needed.

Event payload includes: message_id, chat_id, sender.open_id, message.content, message.msg_type

Batch Notify Multiple Groups

1. Prepare list of chat_ids (from mcp__lark-mcp__im.v1.chat.list)
2. Loop: for each chat_id call mcp__lark-mcp__im.v1.message.create
   → throttle to avoid rate limits: ~5 req/sec recommended

# Tool: mcp__lark-mcp__im.v1.chat.update
path:
  chat_id: "oc_xxx"
data:
  owner_id: "ou_new_owner"
useUAT: true

Workflow: Post Meeting Notes to Group After VC

1. [Meeting ends] → get minute_token from calendar event or meeting recording

2. mcp__lark-mcp__minutes.v1.minuteTranscript.get
   → retrieve full transcript

3. Summarize with AI → key decisions, action items, owners

4. mcp__lark-mcp__im.v1.message.create
   → msg_type: "interactive"
   → send structured card to the meeting group with:
      - Meeting summary
