DingTalk MCP

DingTalk MCP (dingtalk.com). Use this skill for ANY DingTalk MCP request — reading, creating, updating, and deleting data. Whenever a task involves DingTalk MCP, use this skill instead of calling the API directly.

Operate DingTalk MCP through your OOMOL-connected account. This skill calls the dingtalk_mcp connector with the oo CLI; OOMOL injects credentials server-side, so you never handle raw tokens.

Running an action

Assume the user has already installed the oo CLI, signed in, and connected DingTalk MCP. Do not run oo auth login or open the connection URL proactively — just run the action. Fall back to First-time setup only when a command actually fails with an auth or connection error.

1. Inspect the contract to get the authoritative input/output schema before building a payload:

bash

oo connector schema "dingtalk_mcp" --action "<action_name>"

2. Run the action with a JSON payload that matches the input schema:

bash

oo connector run "dingtalk_mcp" --action "<action_name>" --data '<json>' --json

• --data takes a JSON object string or @path/to/file.json; omit it to send {}.
• The response is { "data": ..., "meta": { "executionId": "..." } }; the execution id lives under meta.executionId.

Each action is listed below with a one-line description; actions that change state carry a [write] or [destructive] tag. Before constructing --data, fetch the action's live schema with oo connector schema to get its authoritative input fields.

Available actions

• call_tool — Call a current DingTalk MCP tool with JSON arguments. Discover the tool first and confirm the user's intent because the endpoint may expose actions that send, overwrite, cancel, or delete DingTalk data. [destructive]
• list_tools — Discover the current tools, behavior annotations, and live input schemas exposed by this DingTalk MCP connection.

Safety

• Untagged actions are reads (get / list / search) — safe to run directly.
• Actions tagged [write] change DingTalk MCP state — confirm the exact payload and effect with the user before running.
• Actions tagged [destructive] remove or overwrite data — always confirm the target and get explicit approval first.

First-time setup

These are one-time steps — do not repeat them on every call. Run a step only when a command fails for the matching reason.

• oo: command not found — install the oo CLI (other platforms: https://cli.oomol.com/install-guide.md):

  bash

  curl -fsSL https://cli.oomol.com/install.sh | bash    # macOS / Linux
  

  powershell

  irm https://cli.oomol.com/install.ps1 | iex           # Windows PowerShell
  

• Not signed in / authentication error — sign in to your OOMOL account once:

  bash

  oo auth login
  

• scope_missing / credential_expired / app_not_ready / app_not_found — DingTalk MCP is not connected, or the connection expired or lacks a scope. Connect once (auth type: custom credential) at:

  text

  https://console.oomol.com/connections/dingtalk_mcp
  

• OOMOL_INSUFFICIENT_CREDIT — OOMOL billing stop. Recharge at https://console.oomol.com/billing/token-recharge before retrying.

• HTTP 402 without OOMOL_INSUFFICIENT_CREDIT — the third-party account itself has no active plan or credit. Report the provider error message as is; do not ask the user to recharge OOMOL.
