How to connect Vantage to Hermes Agent
Connect Vantage to Hermes with ClawLink in one click — 134 tools your AI agent can call from chat via hosted OAuth. No API keys, no manual setup.
VantageOAUTH2MCPVantage MCP lets agents analyze authorized cloud costs, reports, resources, tags, budgets, anomalies, and optimization recommendations, and perform supported FinOps management actions.. Once connected, Hermes Agent can read and act on Vantage from chat — pairing, token refresh, and tool wiring handled for you.
Most guides for giving Hermes Agent Vantage 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 Vantage setup: pair once in the browser and your always-on Hermes agent can act on Vantage for you, reading and doing real work on your behalf with no auth, token refresh, or tool wiring to build yourself.
Copy this prompt into Hermes to install the plugin and pair your account.
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. It prints an approval link, so show me the link and stop, don't wait:
hermes clawlink begin
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 Vantage.

Use it from chat
Ask Hermes Agent: "What can you do with Vantage?"
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 Vantage in the ClawLink dashboard — a one-click OAuth approval, no API keys.
Verify the connection by asking Hermes:
Use Vantage to mcp get anomaly 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 Vantage is connected in the dashboard, that agent calls the same 134 Vantage tools over MCP. Full setup for MCP clients and shell agents: connect apps to any AI agent.

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 Hermes Agent. That is fine if you want to build and maintain the integration yourself. Most teams just want Vantage working from chat.
| Manual | ClawLink | |
|---|---|---|
| Connection flow | Register a Vantage app, configure redirect URLs, manage consent details, and reconnect users when auth settings drift. | Users connect Vantage 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 Vantage. | 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 Vantage actions to the runtime in a format your agent can reliably use. | 134 tools for Vantage are already exposed through ClawLink, so the agent can read and act from chat immediately. |
ClawLink vs. Composio
Composio also exposes Vantage 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 Vantage in the browser, and the 134 tools above work from chat. There is no SDK, no config file, and no API key handling. Choosing between them? Read the full Composio alternatives comparison.
Troubleshooting
Hermes paired but still can't use Vantage
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 Vantage 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 Vantage tools
Vantage 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 Vantage 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.
Vantage 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 Vantage and complete the consent flow in the same browser session. Partial OAuth approvals or switching accounts mid-flow can leave the connection incomplete.
