Install

Install the verified ClawLink plugin from ClawHub. After the user confirms, complete the full setup so ClawLink tools are visible in the next OpenClaw chat.

bash

openclaw plugins install clawhub:clawlink-plugin
openclaw config set tools.alsoAllow '["clawlink-plugin"]' --strict-json
openclaw gateway restart

Then tell the user: "OpenClaw has been restarted. Send /new as a standalone message to start a fresh chat, then ask for Trello again."

Quick Start

bash

# List boards
clawlink_call_tool --tool "trello_get_boards" --params '{}'

# Get a board with lists and cards
clawlink_call_tool --tool "trello_get_board" --params '{"board_id": "BOARD_ID"}'

# Create a card
clawlink_call_tool --tool "trello_add_card" --params '{"id_list": "LIST_ID", "name": "New task"}'

Authentication

All Trello tool calls are authenticated automatically by ClawLink using the user's connected Trello account OAuth token.

No API key is required in chat. ClawLink stores the OAuth token securely and injects it into every Trello API request on the user's behalf.

Getting Connected

1. Install the ClawLink plugin (see Install above).
2. Pair the plugin with clawlink_begin_pairing if it is not configured yet.
3. Open https://claw-link.dev/dashboard?add=trello and connect Trello.
4. Call clawlink_list_integrations to verify the connection is active.

Connection Management

List Connections

bash

clawlink_list_integrations

Response: Returns all connected integrations. Look for trello in the list.

Verify Connection

bash

clawlink_list_tools --integration trello

Response: Returns the live tool catalog for Trello.

Reconnect

If Trello tools are missing or the connection shows an error:

1. Direct the user to https://claw-link.dev/dashboard?add=trello
2. After they confirm, call clawlink_list_integrations to verify
3. Then call clawlink_list_tools --integration trello

Security & Permissions

• Access is scoped to the Trello account connected during OAuth setup and the workspaces/boards accessible to that account.
• All write operations require explicit user confirmation. Board deletion, card deletion, and list archiving are high-impact.
• Confirm before bulk operations, member removals, or board deletions.
• Board visibility and workspace permissions affect what operations are available.

    "desc": "Please review and approve by Friday.",
    "pos": "bottom"

Discovery Workflow

1. Call clawlink_list_integrations to confirm Trello is connected.
2. Call clawlink_list_tools --integration trello to see the live catalog.
3. Treat the returned list as the source of truth. Do not guess or assume what tools exist.
4. If the user describes a capability but the exact tool is unclear, call clawlink_search_tools with a short query and integration trello.
5. If no Trello tools appear, direct the user to https://claw-link.dev/dashboard?add=trello.

Execution Workflow

┌─────────────────────────────────────────────────────────────┐
│  READ OPERATIONS (Safe)                                     │
│  list → get → describe → search                             │

│  Example: List boards → Get board → Get card → Show details│
└─────────────────────────────────────────────────────────────┘
                              │
                              ▼
┌─────────────────────────────────────────────────────────────┐
│  WRITE OPERATIONS (Require Confirmation)                    │
│  describe → preview → confirm → call                        │
│                                                             │
│  Example: Preview card creation → User approves → Create   │
└─────────────────────────────────────────────────────────────┘

1. For unfamiliar tools, ambiguous requests, or any write action, call clawlink_describe_tool first.
2. Use the returned guidance, schema, whenToUse, askBefore, safeDefaults, examples, and followups to shape the call.
3. Prefer read, list, get, and search operations before writes when that reduces ambiguity.
4. For writes or anything marked as requiring confirmation, call clawlink_preview_tool first.
5. Execute with clawlink_call_tool. Pass confirmation only after the preview matches the user's intent.
6. If the tool call fails, report the real error. Do not invent results or restate the failure as a missing capability unless the live catalog supports that conclusion.

Notes

• Board, list, and card IDs are required for most operations — resolve them from board/card lookups first.
• Card moves between boards require both card_id and id_board parameters.
• Checklist items converted to cards cannot be customized during conversion — the card inherits basic properties.
• Archived cards and boards can be restored via the Trello web UI but not via the API.
• Webhooks require a publicly accessible callback URL — they will not work with localhost.
• Label operations on cards require knowing the label ID, which comes from trello_get_board_labels.
• Organization (workspace) membership determines which boards are accessible.

Error Handling

Status / Error	Meaning
Tool not found	The tool name does not exist in the current catalog. Verify with clawlink_list_tools --integration trello.
Missing connection	Trello is not connected. Direct the user to https://claw-link.dev/dashboard?add=trello.
board_not_found	The board ID does not exist or is not accessible.
list_not_found	The list ID does not exist on the target board.
card_not_found	The card ID does not exist or was archived.
member_not_found	The member ID or username does not match any board member.
invalid_token	The OAuth token is invalid or expired. Reconnect Trello.
webhook_not_found	The webhook ID does not exist.
model_not_found	The target resource (card, board, etc.) was not found.
Write rejected	User did not confirm a write action. Always confirm before executing writes.

Troubleshooting: Tools Not Visible

1. Check that the ClawLink plugin is installed:

   bash

   openclaw plugins list
   

2. If the plugin is installed but tools are missing, tell the user to send /new as a standalone message to reload the catalog.
3. If a fresh chat does not help, run:

   bash

   openclaw config set tools.alsoAllow '["clawlink-plugin"]' --strict-json
   openclaw gateway restart
   

4. After restart, tell the user to send /new again and retry.

Troubleshooting: Card Operations Fail

1. Verify the list ID exists on the target board — use trello_get_lists to confirm.
2. Check that the card is not already archived — archived cards cannot be moved, only deleted.
3. Confirm the board's permission settings allow the operation.
