# How to connect Calendly to Hermes Agent (no API keys) > Connect Calendly to Hermes with ClawLink in one click — 51 tools your AI agent can call from chat via hosted OAuth. No API keys, no manual setup. Web version: https://claw-link.dev/hermes/calendly Most guides for giving Hermes Agent Calendly access start with registering your own OAuth app or pasting API keys into env files, then leave the token refresh and tool wiring to you. ClawLink gives Hermes a more practical Calendly setup: pair once in the browser and your always-on Hermes agent can act on Calendly for you, reading and doing real work on your behalf with no auth, token refresh, or tool wiring to build yourself. **Start here — paste this into Hermes to set up ClawLink:** > Set up ClawLink for Hermes and tell me when it's ready. > 1. Install the plugin: `hermes plugins install ClawLink-HQ/hermes-plugin --enable` > 2. Start pairing with `hermes clawlink begin`. It prints an approval link, so show me the link and stop, don't wait. > 3. I'll approve it in my browser, then reply "approved". > 4. When I say approved, finish setup: `hermes clawlink finish` > 5. Then run `hermes clawlink test` and tell me whether ClawLink is ready. ## Setup It takes three steps to connect Hermes to Calendly. 1. **Install ClawLink** — add the plugin to Hermes Agent once. 2. **Connect Calendly** — one-click OAuth in the ClawLink dashboard. 3. **Use it from chat** — ask Hermes Agent in plain English. **Alternative for any agent (no plugin needed):** if the Hermes Agent 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 calendly # connect Calendly (browser OAuth) npx -y @useclawlink/cli actions calendly # list available actions npx -y @useclawlink/cli run calendly --input '' # execute (add --confirm for writes) ``` ### Install by command The prompt above walks Hermes through this. By hand, it is four commands and a browser approval: ```bash hermes plugins install ClawLink-HQ/hermes-plugin --enable hermes clawlink begin # prints an approval link — open it and approve hermes clawlink finish # after approving in the browser hermes clawlink test ``` Then connect Calendly in the [ClawLink dashboard](https://claw-link.dev/dashboard) — a one-click OAuth approval, no API keys. Verify the connection by asking Hermes: > Create it in Calendly for me, then confirm the important fields before you finish. ### Using a different agent? The Hermes 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 Calendly is connected in the dashboard, that agent calls the same 51 Calendly tools over MCP.

ClawLink connects Calendly to Hermes Agent and exposes 51 Calendly 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 OpenClaw instead? The [OpenClaw Calendly integration](https://claw-link.dev/openclaw/calendly) works the same way. ## What the Hermes Agent Calendly integration can do 51 Calendly tools are ready for Hermes Agent once the account is connected.

That is fine if you want to build and maintain the integration yourself. Most teams just want Calendly working from chat. | | Manual | ClawLink | |---|---|---| | **Connection flow** | Register a Calendly app, configure redirect URLs, manage consent details, and reconnect users when auth settings drift. | Users connect Calendly 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 Calendly. | 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 Calendly actions to the runtime in a format your agent can reliably use. | 51 tools for Calendly are already exposed through ClawLink, so the agent can read and act from chat immediately. | ## ClawLink vs. Composio Composio also exposes Calendly 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 Hermes Agent users instead. You install the plugin once, connect Calendly in the browser, and the 51 tools above work from chat. There is no SDK, no config file, and no API key handling. Choosing between them?

If you ran finish before approving, or the approval link expired, run `hermes clawlink begin` again to get a fresh link. Confirm the plugin was installed with `--enable`, then verify with `hermes clawlink test`. ### Connection succeeds but no tools appear Reconnect Calendly 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 Calendly tools Calendly 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 Calendly 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. ### Calendly 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 Calendly 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 Hermes Agent Calendly integration? Yes. ClawLink is the fastest way to connect Hermes to Calendly: link your Calendly account once in the browser and Hermes Agent can call the Calendly API through 51 ready-made tools — no custom code or token handling. ### How do I connect Calendly to Hermes with ClawLink? Install the plugin with `hermes plugins install ClawLink-HQ/hermes-plugin --enable`, then pair once: run `hermes clawlink begin`, approve the link in your browser, and run `hermes clawlink finish`. Connect Calendly in the dashboard and Hermes can use it from the next message — no config files or API keys to manage. ### How long does it take to connect Calendly to Hermes Agent? About two minutes. Sign in, click Connect next to Calendly in the dashboard, authenticate, and Hermes Agent can use it from the next chat message. ### Why use ClawLink instead of wiring Calendly up myself? The alternative to ClawLink is usually manual OAuth app setup plus your own token handling, permission troubleshooting, and tool plumbing for Hermes Agent. That is fine if you want to build and maintain the integration yourself. Most teams just want Calendly working from chat. ### Hermes paired but still can't use Calendly Pairing is a two-step handshake: run `hermes clawlink begin`, approve the link in your browser, then run `hermes clawlink finish`. If you ran finish before approving, or the approval link expired, run `hermes clawlink begin` again to get a fresh link. Confirm the plugin was installed with `--enable`, then verify with `hermes clawlink test`. ## Related - [DocuSign](https://claw-link.dev/hermes/docusign) — Send, sign, and manage agreements and envelopes - [Hermes Trello integration](https://claw-link.dev/hermes/trello) — Manage boards, lists, and cards - [Connect Moco](https://claw-link.dev/hermes/moco) — MOCO is a business management software offering project management, time tracking, and invoicing solutions.
