How to connect Graphhopper to Hermes Agent
Connect Graphhopper to Hermes with ClawLink: paste your Graphhopper key once and 13 tools work from chat. No MCP server to run, nothing stored on your machine.
GraphhopperAPI KEYMCPGraphHopper Directions API provides enterprise-grade routing services, including route planning, optimization, geocoding, and more, for various vehicle types.. Once connected, Hermes Agent can read and act on Graphhopper from chat — pairing, token refresh, and tool wiring handled for you.
Most guides for giving Hermes Agent Graphhopper 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 Graphhopper setup: pair once in the browser and your always-on Hermes agent can act on Graphhopper for you, reading and doing real work on your behalf with no auth, token refresh, or tool wiring to build yourself.
Setup
It takes three steps to connect Hermes to Graphhopper.
1Install and pair
Install the ClawLink plugin, then pair Hermes with a one-time browser approval:
hermes plugins install ClawLink-HQ/hermes-plugin --enable- 2
Connect Graphhopper
Paste your API key in the dashboard.
- 3
Use it from chat
Ask Hermes Agent: "What can you do with Graphhopper?"
Install by command
The prompt above walks Hermes through this. By hand, it is four commands and a browser approval:
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 testThen connect Graphhopper in the ClawLink dashboard — paste your Graphhopper API key once.
Verify the connection by asking Hermes:
Use Graphhopper to cluster post and walk me through the result in plain English.
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:
npx -y @useclawlink/cli loginlogin opens the same browser approval and stores a credential locally. Once Graphhopper is connected in the dashboard, that agent calls the same 13 Graphhopper tools over MCP. Full setup for MCP clients and shell agents: connect apps to any AI agent.
Graphhopper MCP for Hermes
Looking for a Graphhopper MCP server for Hermes Agent? ClawLink connects Graphhopper to Hermes Agent and exposes 13 Graphhopper tools your agent can call over MCP, with hosted auth and nothing to run or maintain yourself. Using OpenClaw instead? The OpenClaw Graphhopper integration works the same way.

ClawLink vs. building it yourself
The alternative to ClawLink is usually manual API key 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 Graphhopper working from chat.
| Manual | ClawLink | |
|---|---|---|
| Credential handling | Collect, validate, store, and rotate the Graphhopper API key yourself, then make sure every tool call uses the right account. | Users complete the hosted ClawLink setup once and the connected Graphhopper 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 Graphhopper. | 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 Graphhopper actions to the runtime in a format your agent can reliably use. | 13 tools for Graphhopper are already exposed through ClawLink, so the agent can read and act from chat immediately. |
ClawLink vs. Composio
Composio also exposes Graphhopper 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 Graphhopper in the browser, and the 13 tools above work from chat. There is no SDK and no config file, and the Graphhopper key you paste at setup is stored server-side rather than kept in your environment. Choosing between them?

Troubleshooting
Hermes paired but still can't use Graphhopper
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.
Connection succeeds but no tools appear
Reconnect Graphhopper 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 Graphhopper tools
Graphhopper 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 Graphhopper 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.
Graphhopper 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 Graphhopper has the right scopes or account access. A valid key can still be too limited for some reads or writes.
