# How to connect Finviz to Hermes Agent (paste one key, 11 tools) > Connect Finviz to Hermes with ClawLink: paste your Finviz key once and 11 tools work from chat. No MCP server to run, nothing stored on your machine. Web version: https://claw-link.dev/hermes/finviz Most guides for giving Hermes Agent Finviz 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 Finviz setup: pair once in the browser and your always-on Hermes agent can act on Finviz 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 Finviz. 1. **Install ClawLink** — add the plugin to Hermes Agent once. 2. **Connect Finviz** — 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 finviz # connect Finviz (browser OAuth) npx -y @useclawlink/cli actions finviz # list available actions npx -y @useclawlink/cli run finviz --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 Finviz in the [ClawLink dashboard](https://claw-link.dev/dashboard) — paste your Finviz API key once. Verify the connection by asking Hermes: > Pull the relevant data from Finviz, summarize it in plain English, and point out anything that needs attention. ### 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 Finviz is connected in the dashboard, that agent calls the same 11 Finviz tools over MCP.

ClawLink connects Finviz to Hermes Agent and exposes 11 Finviz 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 Finviz integration](https://claw-link.dev/openclaw/finviz) works the same way. ## What the Hermes Agent Finviz integration can do 11 Finviz tools are ready for Hermes Agent once the account is connected. ### All 11 Finviz tools for Hermes | Tool | What it does | |---|---| | **Get options chain** `finviz_get_options_chain` | Return the options chain for one ticker, optionally restricted to an expiration date or strike | | **Get portfolio** `finviz_get_portfolio` | Return an existing Finviz portfolio using a configured portfolio URL or portfolio ID | | **Get stock history** `finviz_get_stock_history` | Return OHLCV price history for one ticker at a selected bar timeframe and history range | | **List calendar** `finviz_list_calendar` | Return economic events, company earnings, or company dividends for an inclusive date range | | **List groups** `finviz_list_groups` | Return aggregate Finviz market groups for a selected grouping and data view | | **List insider transactions** `finviz_list_insider_transactions` | Return recent market-wide or ticker-specific insider transactions, filtered to all | | **List investor holdings** `finviz_list_investor_holdings` | Return a bounded prefix of one manager's or fund's complete unpaginated holdings export and | | **List investors** `finviz_list_investors` | Return the institutional-manager or fund directory, optionally narrowed by name | | **List latest filings** `finviz_list_latest_filings` | Return the latest SEC filings for one ticker, optionally filtered by filing category and | | **List news** `finviz_list_news` | Return market, stock, ETF, or crypto news from Finviz | | **Screen stocks** `finviz_screen_stocks` | Return stocks from a configured Finviz screener URL or explicit screener controls | ## Example prompts **Get Options Chain** > Pull the relevant data from Finviz, summarize it in plain English, and point out anything that needs attention. **Get Portfolio** > Pull the relevant data from Finviz, summarize it in plain English, and point out anything that needs attention. **Get Stock History** > Pull the relevant data from Finviz, summarize it in plain English, and point out anything that needs attention. **List Calendar** > List the relevant items in Finviz, group them by priority, and recommend what Hermes should do next. ## 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 Finviz working from chat. | | Manual | ClawLink | |---|---|---| | **Credential handling** | Collect, validate, store, and rotate the Finviz API key yourself, then make sure every tool call uses the right account. | Users complete the hosted ClawLink setup once and the connected Finviz 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 Finviz. | 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 Finviz actions to the runtime in a format your agent can reliably use. | 11 tools for Finviz are already exposed through ClawLink, so the agent can read and act from chat immediately. | ## ClawLink vs. Composio Composio also exposes Finviz 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 Finviz in the browser, and the 11 tools above work from chat. There is no SDK and no config file, and the Finviz 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 Finviz 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 Finviz tools Finviz 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 Finviz 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. ### Finviz 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 Finviz 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 Finviz integration? Yes. ClawLink is the fastest way to connect Hermes to Finviz: link your Finviz account once in the browser and Hermes Agent can call the Finviz API through 11 ready-made tools — no custom code or token handling. ### How do I connect Finviz 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 Finviz in the dashboard and Hermes can use it from the next message — no config files, and the Finviz key you paste is stored server-side instead of in your environment. ### How long does it take to connect Finviz to Hermes Agent? About two minutes. Sign in, click Connect next to Finviz in the dashboard, authenticate, and Hermes Agent can use it from the next chat message. ### Why use ClawLink instead of wiring Finviz 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 Finviz working from chat. ### Hermes paired but still can't use Finviz Pairing is a two-step handshake: run `hermes clawlink begin`, approve the link in your browser, then run `hermes clawlink finish`.
