# How to connect Retell AI to OpenClaw (paste one key, 67 tools) > Connect Retell AI to OpenClaw with ClawLink: paste your Retell AI key once and 67 tools work from chat. No MCP server to run, nothing stored on your machine. Web version: https://claw-link.dev/openclaw/retellai The usual route to Retell AI access for OpenClaw is an MCP server you configure and keep running, plus your own OAuth app or API keys. ClawLink gives OpenClaw a more practical Retell AI setup: install one ClawHub skill, connect Retell AI in the browser, and OpenClaw can call real Retell AI actions from any chat surface with no auth, token refresh, or tool wiring to build yourself. **Start here:** install the ClawLink plugin (`openclaw plugins install clawhub:clawlink-plugin`), pair it in the browser, then connect the app in the ClawLink dashboard. The interactive install prompt is on the web version of this page: https://claw-link.dev/openclaw/retellai ## Setup It takes three steps to connect OpenClaw to Retell AI. 1. **Install ClawLink** — add the plugin to OpenClaw once. 2. **Connect Retell AI** — one-click OAuth in the ClawLink dashboard. 3. **Use it from chat** — ask OpenClaw in plain English. **Alternative for any agent (no plugin needed):** if the OpenClaw plugin route isn't available or doesn't work, any AI agent with shell access can use the ClawLink CLI instead: ```bash npx -y @useclawlink/cli login # sign in via browser — no API key to paste npx -y @useclawlink/cli connect retellai # connect Retell AI (browser OAuth) npx -y @useclawlink/cli actions retellai # list available actions npx -y @useclawlink/cli run retellai --input '' # execute (add --confirm for writes) ``` ### Install by command The setup prompt above does all of this in one paste. By hand, it is one install command plus a browser approval: ```bash openclaw plugins install clawhub:clawlink-plugin ``` Then ask OpenClaw to set up ClawLink. It starts browser pairing and prints an approval link — open it, approve the device, return to the chat, and say `done`. Finally, connect Retell AI in the [ClawLink dashboard](https://claw-link.dev/dashboard) — paste your Retell AI API key once. Verify the connection by asking OpenClaw: > Use Retell AI to add community voice and walk me through the result in plain English. ### Using a different agent? The OpenClaw plugin is one client of ClawLink's MCP server. Claude Code, Cursor, Codex, or any agent that can run a shell command pairs with the same ClawLink account through the CLI: ```bash npx -y @useclawlink/cli login ``` `login` opens the same browser approval and stores a credential locally. Once Retell AI is connected in the dashboard, that agent calls the same 67 Retell AI tools over MCP.

ClawLink connects Retell AI to OpenClaw and exposes 67 Retell AI 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 Hermes instead? The [Hermes Retell AI integration](https://claw-link.dev/hermes/retellai) works the same way. ## What the OpenClaw Retell AI integration can do 67 Retell AI tools are ready for OpenClaw once the account is connected. The 30 below are the ones people reach for most; your agent can call all 67. ### 30 of 67 Retell AI tools for OpenClaw | Tool | What it does | |---|---| | **Add community voice** `retellai_add_community_voice` | Add a community voice from ElevenLabs to your Retell voice library.

That is fine if you want to build and maintain the integration yourself. Most teams just want Retell AI working from chat. | | Manual | ClawLink | |---|---|---| | **Credential handling** | Collect, validate, store, and rotate the Retell AI API key yourself, then make sure every tool call uses the right account. | Users complete the hosted ClawLink setup once and the connected Retell AI account becomes available to the agent without you building credential management. | | **Ongoing maintenance** | You own refresh logic, permission debugging, environment config, and every provider-specific edge case for Retell AI. | 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 Retell AI actions to the runtime in a format your agent can reliably use. | 67 tools for Retell AI are already exposed through ClawLink, so the agent can read and act from chat immediately. | ## ClawLink vs. Composio Composio also exposes Retell AI 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 OpenClaw users instead. You install the plugin once, connect Retell AI in the browser, and the 67 tools above work from chat. There is no SDK and no config file, and the Retell AI key you paste at setup is stored server-side rather than kept in your environment. Choosing between them?

Make sure Retell AI is connected in the dashboard, then start a fresh chat so OpenClaw reloads the tool catalog. If OpenClaw runs as a persistent gateway, restart it so the new tools register. ### Connection succeeds but no tools appear Reconnect Retell AI 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 Retell AI tools Retell AI 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 Retell AI 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. ### Retell AI 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. ### API key setup works but results look incomplete Double-check that the API key for Retell AI has the right scopes or account access. A valid key can still be too limited for some reads or writes. ### Is there a OpenClaw Retell AI integration? Yes. ClawLink is the fastest way to connect OpenClaw to Retell AI: link your Retell AI account once in the browser and OpenClaw can call the Retell AI API through 67 ready-made tools — no custom code or token handling. ### How do I add Retell AI to OpenClaw with ClawLink? Paste the setup prompt from this page into OpenClaw. It installs the ClawLink Retell AI skill from ClawHub, then you click Connect in the dashboard to authorize Retell AI. OpenClaw calls the tools from the next message — no config files, and the Retell AI key you paste is stored server-side instead of in your environment. ### How long does it take to connect Retell AI to OpenClaw? About two minutes. Sign in, click Connect next to Retell AI in the dashboard, authenticate, and OpenClaw can use it from the next chat message. ### Why use ClawLink instead of wiring Retell AI up myself? The alternative to ClawLink is usually manual API key setup plus your own token handling, permission troubleshooting, and tool plumbing for OpenClaw. That is fine if you want to build and maintain the integration yourself. Most teams just want Retell AI working from chat. ### OpenClaw installed the Retell AI skill but can't call the tools The ClawHub skill teaches OpenClaw about Retell AI, but the calls run through the ClawLink plugin and your connected account.
