# How to connect Trello to Grok Bot (no API keys) > Connect Trello to Grok Bot with ClawLink in one click — 322 tools your AI agent can call from chat via hosted OAuth. No API keys, no manual setup. Web version: https://claw-link.dev/grokbot/trello Grok Bot runs on its own cloud computer, so most Trello guides send you to register an OAuth app and paste keys into a sandbox that resets. ClawLink gives Grok Bot a more practical Trello setup: it runs one CLI command, you approve once in the browser, and Grok Bot can call real Trello actions from chat with no auth, token refresh, or tool wiring to build yourself. **Start here — paste this into Grok Bot to set up ClawLink:** > Set up ClawLink for me and tell me when it's ready. > 1. Pair this machine. It prints an approval link, so show me the link and stop, don't wait: `npx -y @useclawlink/cli login` > 2. I'll approve it in my browser, then reply "approved". > 3. When I say approved, connect the app: `npx -y @useclawlink/cli connect trello` > 4. Then run `npx -y @useclawlink/cli whoami` and tell me whether ClawLink is ready. ## Setup It takes three steps to connect Grok Bot to Trello. 1. **Pair from the terminal** — ask Grok Bot to run `npx -y @useclawlink/cli login` and approve the link it prints. 2. **Connect Trello** — `npx -y @useclawlink/cli connect trello`, then approve in the browser. 3. **Use it from chat** — ask Grok Bot in plain English. **The same CLI works from any agent with shell access:** ```bash npx -y @useclawlink/cli login # sign in via browser — no API key to paste npx -y @useclawlink/cli connect trello # connect Trello (browser OAuth) npx -y @useclawlink/cli actions trello # list available actions npx -y @useclawlink/cli run trello --input '' # execute (add --confirm for writes) ``` ### Install by command The prompt above does all of this. By hand, it is two commands Grok Bot runs in its own terminal, and one browser approval: ```bash npx -y @useclawlink/cli login # prints an approval link, approve it in your browser npx -y @useclawlink/cli connect trello ``` Pair once and it sticks: the key is written to ~/.clawlink/credentials.json inside Grok Bot's sandbox, so it survives between sessions. Prefer native tools over shell commands? Add `https://claw-link.dev/api/mcp` as a custom connector at grok.com/connectors and approve the ClawLink sign-in. Same account, no CLI. Verify the connection by asking Grok Bot: > Use Trello to add boards and walk me through the result in plain English. ### Using a different agent? The CLI above is not specific to Grok Bot. Claude Code, Cursor, Codex, or any agent that can run a shell command pairs with the same ClawLink account the same way: ```bash npx -y @useclawlink/cli login ``` `login` opens the same browser approval and stores a credential locally. Once Trello is connected in the dashboard, that agent calls the same 322 Trello tools over MCP.

ClawLink connects Trello to Grok Bot and exposes 322 Trello tools your agent can call over [MCP](https://claw-link.dev/learn/what-is-an-mcp-server), with [hosted auth](https://claw-link.dev/learn/oauth-for-ai-agents) and nothing to run or maintain yourself. Using a different agent? The [OpenClaw Trello integration](https://claw-link.dev/openclaw/trello) and the [Hermes Trello integration](https://claw-link.dev/hermes/trello) connect the same ClawLink account the same way. ## What the Grok Bot Trello integration can do 322 Trello tools are ready for Grok Bot once the account is connected.

That is fine if you want to build and maintain the integration yourself. Most teams just want Trello working from chat. | | Manual | ClawLink | |---|---|---| | **Connection flow** | Register a Trello app, configure redirect URLs, manage consent details, and reconnect users when auth settings drift. | Users connect Trello through the hosted browser flow and ClawLink keeps the token lifecycle out of your app code. | | **Ongoing maintenance** | You own refresh logic, permission debugging, environment config, and every provider-specific edge case for Trello. | ClawLink handles the repetitive integration plumbing so your team can focus on the workflow instead of the infrastructure. | | **Agent usability** | You still need to expose the right Trello actions to the runtime in a format your agent can reliably use. | 322 tools for Trello are already exposed through ClawLink, so the agent can read and act from chat immediately. | ## ClawLink vs. Composio Composio also exposes Trello to AI agents. It is developer infrastructure: Python and TypeScript SDKs, an MCP server, and a catalog past 1,000 apps, aimed at teams shipping agent products. ClawLink is built for Grok Bot users instead. You install the plugin once, connect Trello in the browser, and the 322 tools above work from chat. There is no SDK, no config file, and no API key handling. Choosing between them?

You do not need one. Ask Grok Bot to run `npx -y @useclawlink/cli login` in its terminal instead. The CLI is a shell command, not an MCP server. If you would rather have native tools, add `https://claw-link.dev/api/mcp` as a custom connector at grok.com/connectors and approve the ClawLink sign-in. ### Connection succeeds but no tools appear Reconnect Trello from the dashboard, then start a fresh chat if the runtime still has the old tool catalog loaded. ### "Tool schema not loaded yet" error when calling Trello tools Trello tool schemas load on demand the first time a tool runs and are cached after that, so this error usually clears on its own: wait a few seconds and retry the same request. If every Trello call keeps failing with it in a fresh chat, reconnect from the dashboard, and contact support if it still persists — that pattern points to a configuration problem on our side, not something you can fix by reconnecting again. ### Trello returns 403 or "permission denied" on one action while others work Two usual causes. The connected account may not have access to the specific workspace, inbox, store, or project in the request — check that first. If access looks right, the agent may have sent a placeholder value (like "YOUR_ID" or an example id from documentation) instead of a real one: ask it to run a list or search tool first, then retry the action with a real id from those results. Most failures at this stage are one of these two, not ClawLink bugs. ### OAuth finished in the browser but the account is still missing Try reconnecting Trello and complete the consent flow in the same browser session. Partial OAuth approvals or switching accounts mid-flow can leave the connection incomplete. ### Is there a Grok Bot Trello integration? Yes. ClawLink is the fastest way to connect Grok Bot to Trello: link your Trello account once in the browser and Grok Bot can call the Trello API through 322 ready-made tools — no custom code or token handling. ### How do I connect Trello to Grok Bot with ClawLink? Ask Grok Bot to run `npx -y @useclawlink/cli login` in its terminal and approve the link it prints, then `npx -y @useclawlink/cli connect trello` to authorize Trello. Grok Bot calls the tools from the next message, and the pairing persists in its sandbox, so this is a one-time step: no config files or API keys to manage. ### How long does it take to connect Trello to Grok Bot? About two minutes. Sign in, click Connect next to Trello in the dashboard, authenticate, and Grok Bot can use it from the next chat message. ### Why use ClawLink instead of wiring Trello up myself? The alternative to ClawLink is usually manual OAuth app setup plus your own token handling, permission troubleshooting, and tool plumbing for Grok Bot. That is fine if you want to build and maintain the integration yourself. Most teams just want Trello working from chat. ### Grok Bot says it cannot add ClawLink as an MCP server Grok Bot only attaches MCP servers that are reachable over the public internet, so a local stdio server is refused.
