# How to connect Fathom to OpenClaw (no API keys) > Connect Fathom to OpenClaw with ClawLink in one click — hosted OAuth, no API keys, no manual setup. Run real actions straight from chat. Web version: https://claw-link.dev/openclaw/fathom The usual route to Fathom 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 Fathom setup: install one ClawHub skill, connect Fathom in the browser, and OpenClaw can call real Fathom actions from any chat surface with no auth, token refresh, or tool wiring to build yourself. ## Fathom MCP for OpenClaw Looking for a Fathom MCP server for OpenClaw? ClawLink connects Fathom to OpenClaw and exposes 0 Fathom 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 Fathom integration](https://claw-link.dev/hermes/fathom) works the same way. **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/fathom ## Setup It takes three steps to connect OpenClaw to Fathom. 1. **Install ClawLink** — add the plugin to OpenClaw once. 2. **Connect Fathom** — 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 fathom # connect Fathom (browser OAuth) npx -y @useclawlink/cli actions fathom # list available actions npx -y @useclawlink/cli run fathom --input '' # execute (add --confirm for writes) ``` ## What the OpenClaw Fathom integration can do - **Communication** — tools appear after Fathom is connected. ## Example prompts No example prompts are available yet. ## ClawLink vs. building it yourself The alternative to ClawLink is usually manual OAuth app 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 Fathom working from chat. | | Manual | ClawLink | |---|---|---| | **Connection flow** | Register a Fathom app, configure redirect URLs, manage consent details, and reconnect users when auth settings drift. | Users connect Fathom 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 Fathom. | 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 Fathom actions to the runtime in a format your agent can reliably use. | 0 tools for Fathom are already exposed through ClawLink, so the agent can read and act from chat immediately. | ## ClawLink vs. Composio Composio also exposes Fathom 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 Fathom in the browser, and the connected Fathom account works from chat. There is no SDK, no config file, and no API key handling. Choosing between them?

Make sure Fathom 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 Fathom 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 Fathom tools Fathom 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 Fathom 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. ### Fathom 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 Fathom 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 OpenClaw Fathom integration? Yes. ClawLink is the fastest way to connect OpenClaw to Fathom: link your Fathom account once in the browser and OpenClaw can call the Fathom API through ready-made tools — no custom code or token handling. ### How do I add Fathom to OpenClaw with ClawLink? Paste the setup prompt from this page into OpenClaw. It installs the ClawLink Fathom skill from ClawHub, then you click Connect in the dashboard to authorize Fathom. OpenClaw calls the tools from the next message — no config files or API keys. ### How long does it take to connect Fathom to OpenClaw? About two minutes. Sign in, click Connect next to Fathom in the dashboard, authenticate, and OpenClaw can use it from the next chat message. ### Why use ClawLink instead of wiring Fathom up myself? The alternative to ClawLink is usually manual OAuth app 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 Fathom working from chat. ### OpenClaw installed the Fathom skill but can't call the tools The ClawHub skill teaches OpenClaw about Fathom, but the calls run through the ClawLink plugin and your connected account.
