How to connect Harvest to OpenClaw (no API keys)
Connect Harvest to OpenClaw with ClawLink in one click — hosted OAuth, no API keys, no manual setup. Run real actions straight from chat.
The usual route to Harvest 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 Harvest setup: install one ClawHub skill, connect Harvest in the browser, and OpenClaw can call real Harvest actions from any chat surface with no auth, token refresh, or tool wiring to build yourself.
Harvest MCP for OpenClaw
Looking for a Harvest MCP server for OpenClaw? ClawLink connects Harvest to OpenClaw and exposes 0 Harvest tools your agent can call over MCP, with hosted auth and nothing to run or maintain yourself. Using Hermes instead? The Hermes Harvest integration works the same way.
Copy this prompt into OpenClaw, or open the Harvest skill on ClawHub.
Before installing anything, inspect the ClawHub skill metadata and setup requirements.
If the skill asks you to install a third-party package or CLI, verify its source, maintainer, and package contents before running the install command.
Install the skill "Harvest" (hith3sh/harvest) from ClawHub only after those checks pass.

Keep the work scoped to this skill only.
After install, help me finish setup from verified skill metadata.
Use only the metadata you can verify from ClawHub; do not invent missing requirements.

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 Harvest working from chat.
| Manual | ClawLink | |
|---|---|---|
| Connection flow | Register a Harvest app, configure redirect URLs, manage consent details, and reconnect users when auth settings drift. | Users connect Harvest 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 Harvest. | 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 Harvest actions to the runtime in a format your agent can reliably use. | 0 tools for Harvest are already exposed through ClawLink, so the agent can read and act from chat immediately. |
ClawLink vs. Composio
Composio also exposes Harvest 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 Harvest in the browser, and the connected Harvest account works from chat. There is no SDK, no config file, and no API key handling. Choosing between them? Read the full Composio alternatives comparison.
Troubleshooting
OpenClaw installed the Harvest skill but can't call the tools
The ClawHub skill teaches OpenClaw about Harvest, but the calls run through the ClawLink plugin and your connected account. Make sure Harvest 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 Harvest 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 Harvest tools
Harvest 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 Harvest 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.
Harvest 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 Harvest and complete the consent flow in the same browser session. Partial OAuth approvals or switching accounts mid-flow can leave the connection incomplete.
