# How to connect Openperplex to Hermes Agent (paste one key, 8 tools) > Connect Openperplex to Hermes with ClawLink: paste your Openperplex key once and 8 tools work from chat. No MCP server to run, nothing stored on your machine. Web version: https://claw-link.dev/hermes/openperplex Most guides for giving Hermes Agent Openperplex 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 Openperplex setup: pair once in the browser and your always-on Hermes agent can act on Openperplex 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 Openperplex. 1. **Install ClawLink** — add the plugin to Hermes Agent once. 2. **Connect Openperplex** — one-click OAuth in the ClawLink dashboard. 3. **Use it from chat** — ask Hermes Agent in plain English. **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. **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 openperplex # connect Openperplex (browser OAuth) npx -y @useclawlink/cli actions openperplex # list available actions npx -y @useclawlink/cli run openperplex --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 Openperplex in the [ClawLink dashboard](https://claw-link.dev/dashboard) — paste your Openperplex API key once. Verify the connection by asking Hermes: > Search Openperplex for what I need, summarize the results, and tell me the next best action. ### 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 Openperplex is connected in the dashboard, that agent calls the same 8 Openperplex tools over MCP.

ClawLink connects Openperplex to Hermes Agent and exposes 8 Openperplex 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 Openperplex integration](https://claw-link.dev/openclaw/openperplex) works the same way. ## What the Hermes Agent Openperplex integration can do 8 Openperplex tools are ready for Hermes Agent once the account is connected. ### All 8 Openperplex tools for Hermes | Tool | What it does | |---|---| | **Custom search** `openperplex_custom_search` | Perform a custom search with optional filtering and field selection | | **Custom search stream** `openperplex_custom_search_stream` | Perform custom streaming search with custom prompts | | **Get website markdown** `openperplex_get_website_markdown` | Retrieve the markdown content of a specified website | | **Get website screenshot** `openperplex_get_website_screenshot` | Capture a screenshot of a website | | **Get website text** `openperplex_get_website_text` | Retrieve the main text content of a specified website URL | | **Query from URL** `openperplex_query_from_url` | Query documents from a URL | | **Search** `openperplex_search` | Search documents using query parameters | | **Search stream** `openperplex_search_stream` | Stream search results from OpenPerplex | ## Example prompts **Custom Search** > Search Openperplex for what I need, summarize the results, and tell me the next best action. **Custom Search Stream** > Search Openperplex for what I need, summarize the results, and tell me the next best action. **Get Website Markdown** > Pull the relevant data from Openperplex, summarize it in plain English, and point out anything that needs attention. **Get Website Screenshot** > Pull the relevant data from Openperplex, summarize it in plain English, and point out anything that needs attention. ## 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 Openperplex working from chat. | | Manual | ClawLink | |---|---|---| | **Credential handling** | Collect, validate, store, and rotate the Openperplex API key yourself, then make sure every tool call uses the right account. | Users complete the hosted ClawLink setup once and the connected Openperplex 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 Openperplex. | 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 Openperplex actions to the runtime in a format your agent can reliably use. | 8 tools for Openperplex are already exposed through ClawLink, so the agent can read and act from chat immediately. | ## ClawLink vs. Composio Composio also exposes Openperplex 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 Openperplex in the browser, and the 8 tools above work from chat. There is no SDK and no config file, and the Openperplex key you paste at setup is stored server-side rather than kept in your environment. 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 Openperplex 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 Openperplex tools Openperplex 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 Openperplex 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. ### Openperplex 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 Openperplex has the right scopes or account access. A valid key can still be too limited for some reads or writes. ### Is there a Hermes Agent Openperplex integration? Yes. ClawLink is the fastest way to connect Hermes to Openperplex: link your Openperplex account once in the browser and Hermes Agent can call the Openperplex API through 8 ready-made tools — no custom code or token handling. ### How do I connect Openperplex 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 Openperplex in the dashboard and Hermes can use it from the next message — no config files, and the Openperplex key you paste is stored server-side instead of in your environment. ### How long does it take to connect Openperplex to Hermes Agent? About two minutes. Sign in, click Connect next to Openperplex in the dashboard, authenticate, and Hermes Agent can use it from the next chat message. ### Why use ClawLink instead of wiring Openperplex up myself? 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 Openperplex working from chat. ### Hermes paired but still can't use Openperplex 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 - [Hermes DataRobot integration](https://claw-link.dev/hermes/datarobot) — DataRobot is a machine learning platform that automates model building, deployment, and monitoring, enabling organizations to derive predictive insights from large datasets. - [Chatbotkit](https://claw-link.dev/hermes/chatbotkit) — ChatBotKit is a platform that enables developers to build and manage AI-powered chatbots, offering comprehensive APIs and SDKs for seamless integration into applications. - [Just One API tools](https://claw-link.dev/hermes/just-one-api) — Just One API provides unified access to public social media, creator, entertainment, and ecommerce data across hundreds of metered endpoints.
