# How to connect Alpha Vantage to Hermes Agent (paste one key, 56 tools) > Connect Alpha Vantage to Hermes with ClawLink: paste your Alpha Vantage key once and 56 tools work from chat. No MCP server to run, nothing stored on your machine. Web version: https://claw-link.dev/hermes/alpha-vantage Most guides for giving Hermes Agent Alpha 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 Alpha Vantage setup: pair once in the browser and your always-on Hermes agent can act on Alpha Vantage 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 Alpha Vantage. 1. **Install ClawLink** — add the plugin to Hermes Agent once. 2. **Connect Alpha Vantage** — 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 alpha-vantage # connect Alpha Vantage (browser OAuth) npx -y @useclawlink/cli actions alpha-vantage # list available actions npx -y @useclawlink/cli run alpha-vantage --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 Alpha Vantage in the [ClawLink dashboard](https://claw-link.dev/dashboard) — paste your Alpha Vantage API key once. Verify the connection by asking Hermes: > Use Alpha Vantage to all commodities 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: ```bash npx -y @useclawlink/cli login ``` `login` opens the same browser approval and stores a credential locally. Once Alpha Vantage is connected in the dashboard, that agent calls the same 56 Alpha Vantage tools over MCP.

ClawLink connects Alpha Vantage to Hermes Agent and exposes 56 Alpha Vantage 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 Alpha Vantage integration](https://claw-link.dev/openclaw/alpha-vantage) works the same way. ## What the Hermes Agent Alpha Vantage integration can do 56 Alpha Vantage tools are ready for Hermes Agent once the account is connected. The 30 below are the ones people reach for most; your agent can call all 56. ### 30 of 56 Alpha Vantage tools for Hermes | Tool | What it does | |---|---| | **All commodities** `alpha_vantage_all_commodities` | Retrieve the global price index of all commodities | | **Aluminum** `alpha_vantage_aluminum` | Fetch global aluminum prices | | **Balance sheet** `alpha_vantage_balance_sheet` | Return annual and quarterly balance sheets for a company | | **Brent** `alpha_vantage_brent` | Fetch Brent crude oil prices | | **Cash flow** `alpha_vantage_cash_flow` | Return annual and quarterly cash flow statements for a company | | **Coffee** `alpha_vantage_coffee` | Retrieve the global coffee price series | | **Company overview** `alpha_vantage_company_overview` | Retrieve company overview and fundamental data for individual company stocks | | **Copper** `alpha_vantage_copper` | Fetch global price of copper in monthly, quarterly, and annual intervals | | **Corn** `alpha_vantage_corn` | Retrieve global price of corn in monthly, quarterly, and annual intervals | | **Cotton** `alpha_vantage_cotton` | Retrieve global cotton prices in monthly, quarterly, and annual intervals | | **Cpi** `alpha_vantage_cpi` | Fetch monthly and semiannual Consumer Price Index (CPI) data of the United States | | **Crypto intraday** `alpha_vantage_crypto_intraday` | Retrieve intraday time series data for cryptocurrencies with realtime updates | | **Currency exchange rate** `alpha_vantage_currency_exchange_rate` | Retrieve real-time exchange rate for a currency pair | | **Digital currency daily** `alpha_vantage_digital_currency_daily` | Retrieve daily historical time series for a digital currency traded on a specific market | | **Digital currency monthly** `alpha_vantage_digital_currency_monthly` | Retrieve monthly digital currency prices in a fiat currency | | **Digital currency weekly** `alpha_vantage_digital_currency_weekly` | Retrieve weekly digital currency prices in a fiat currency | | **Durables** `alpha_vantage_durables` | Fetch monthly manufacturers' new orders of durable goods data for the United States | | **Earnings** `alpha_vantage_earnings` | Retrieve annual and quarterly earnings (EPS history) for a specific company symbol | | **Earnings calendar** `alpha_vantage_earnings_calendar` | Return the earnings calendar for the next three months | | **Earnings call transcript** `alpha_vantage_earnings_call_transcript` | Retrieve the earnings call transcript for a given company and quarter | | **Federal funds rate** `alpha_vantage_federal_funds_rate` | Fetch daily, weekly, and monthly federal funds rate data of the United States | | **Fx daily** `alpha_vantage_fx_daily` | Fetch daily time series (open, high, low, close) for a currency pair | | **Fx intraday** `alpha_vantage_fx_intraday` | Retrieve intraday OHLC time series for a forex pair at 1-60 minute intervals (premium endpoint) | | **Fx monthly** `alpha_vantage_fx_monthly` | Get monthly time series (open, high, low, close) for a currency pair | | **Fx weekly** `alpha_vantage_fx_weekly` | Get weekly time series (open, high, low, close) for a currency pair | | **Get dividends** `alpha_vantage_get_dividends` | Retrieve historical dividend payment records for a stock symbol | | **Get historical options** `alpha_vantage_get_historical_options` | Retrieve full historical options chain for a symbol on a specific date with 15+ years of | | **Get sliding window analytics** `alpha_vantage_get_sliding_window_analytics` | Retrieve advanced analytics metrics with sliding window calculations for trend analysis | | **Global quote** `alpha_vantage_global_quote` | Retrieve latest price and volume information for a specified security ticker in realtime | | **Income statement** `alpha_vantage_income_statement` | Fetch annual and quarterly income statements | ## Example prompts **All Commodities** > Use Alpha Vantage to all commodities and walk me through the result in plain English. **Aluminum** > Use Alpha Vantage to aluminum and walk me through the result in plain English. **Balance Sheet** > Use Alpha Vantage to balance sheet and walk me through the result in plain English. **Brent** > Use Alpha Vantage to brent and walk me through the result in plain English. ## 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 Alpha Vantage working from chat. | | Manual | ClawLink | |---|---|---| | **Credential handling** | Collect, validate, store, and rotate the Alpha Vantage API key yourself, then make sure every tool call uses the right account. | Users complete the hosted ClawLink setup once and the connected Alpha Vantage 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 Alpha 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 Alpha Vantage actions to the runtime in a format your agent can reliably use. | 56 tools for Alpha Vantage are already exposed through ClawLink, so the agent can read and act from chat immediately. | ## ClawLink vs. Composio Composio also exposes Alpha 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 Alpha Vantage in the browser, and the 56 tools above work from chat. There is no SDK and no config file, and the Alpha Vantage 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 Alpha 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 Alpha Vantage tools Alpha 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 Alpha 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. ### Alpha 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. ### API key setup works but results look incomplete Double-check that the API key for Alpha Vantage 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 Alpha Vantage integration? Yes. ClawLink is the fastest way to connect Hermes to Alpha Vantage: link your Alpha Vantage account once in the browser and Hermes Agent can call the Alpha Vantage API through 56 ready-made tools — no custom code or token handling. ### How do I connect Alpha Vantage 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 Alpha Vantage in the dashboard and Hermes can use it from the next message — no config files, and the Alpha Vantage key you paste is stored server-side instead of in your environment. ### How long does it take to connect Alpha Vantage to Hermes Agent? About two minutes. Sign in, click Connect next to Alpha Vantage in the dashboard, authenticate, and Hermes Agent can use it from the next chat message. ### Why use ClawLink instead of wiring Alpha Vantage 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 Alpha Vantage working from chat. ### Hermes paired but still can't use Alpha 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.
