# How to connect Coinbase to Hermes Agent (paste one key, 28 tools) > Connect Coinbase to Hermes with ClawLink: paste your Coinbase key once and 28 tools work from chat. No MCP server to run, nothing stored on your machine. Web version: https://claw-link.dev/hermes/coinbase Most guides for giving Hermes Agent Coinbase 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 Coinbase setup: pair once in the browser and your always-on Hermes agent can act on Coinbase 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 Coinbase. 1. **Install ClawLink** — add the plugin to Hermes Agent once. 2. **Connect Coinbase** — 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 coinbase # connect Coinbase (browser OAuth) npx -y @useclawlink/cli actions coinbase # list available actions npx -y @useclawlink/cli run coinbase --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 Coinbase in the [ClawLink dashboard](https://claw-link.dev/dashboard) — paste your Coinbase API key once. Verify the connection by asking Hermes: > Pull the relevant data from Coinbase, 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 Coinbase is connected in the dashboard, that agent calls the same 28 Coinbase tools over MCP.

ClawLink connects Coinbase to Hermes Agent and exposes 28 Coinbase 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 Coinbase integration](https://claw-link.dev/openclaw/coinbase) works the same way. ## What the Hermes Agent Coinbase integration can do 28 Coinbase tools are ready for Hermes Agent once the account is connected. ### All 28 Coinbase tools for Hermes | Tool | What it does | |---|---| | **Get asset details** `coinbase_get_asset_details` | Retrieve detailed information about a specific asset from Coinbase International Exchange | | **Get exchange currency** `coinbase_get_exchange_currency` | Retrieve detailed information about a specific currency from Coinbase Exchange API | | **Get instrument details** `coinbase_get_instrument_details` | Get complete details for a specific trading instrument on Coinbase International Exchange | | **Get instruments funding** `coinbase_get_instruments_funding` | Get historical funding rates for a specific instrument from Coinbase International Exchange | | **Get instruments quote** `coinbase_get_instruments_quote` | Get the current quote for a specific trading instrument on Coinbase International Exchange | | **Get instruments volumes daily** `coinbase_get_instruments_volumes_daily` | Retrieve daily trading volume data for specified instruments on Coinbase International Exchange | | **Get market product book** `coinbase_get_market_product_book` | Get the current order book (market depth) for a specific product | | **Get product** `coinbase_get_product` | Retrieve detailed information about a specific product (trading pair) from Coinbase Exchange | | **Get product book** `coinbase_get_product_book` | Retrieves the order book for a specific product on Coinbase Exchange | | **Get products ticker** `coinbase_get_products_ticker` | Get real-time ticker information for a specific product on Coinbase Exchange | | **Get products volume summary** `coinbase_get_products_volume_summary` | Retrieve volume summaries for all trading products on Coinbase Exchange | | **Get public market trades** `coinbase_get_public_market_trades` | Get public market trades for a specific product (trading pair) | | **Get server time** `coinbase_get_server_time` | Retrieve the current server time from Coinbase Advanced Trade API | | **Get supported networks** `coinbase_get_supported_networks` | Retrieve supported blockchain networks for a specific cryptocurrency asset on Coinbase | | **Get wrapped asset conversion rate** `coinbase_get_wrapped_asset_conversion_rate` | Get the current conversion rate for a wrapped asset on Coinbase Exchange | | **List assets** `coinbase_list_assets` | Retrieve all supported assets from the Coinbase International Exchange | | **List currencies** `coinbase_list_currencies` | Get all known currencies from Coinbase Exchange API | | **List exchange products** `coinbase_list_exchange_products` | Retrieve all known trading pairs from Coinbase Exchange | | **List instruments** `coinbase_list_instruments` | List all instruments available for trading on Coinbase International Exchange | | **List instruments candles** `coinbase_list_instruments_candles` | Retrieve aggregated candle (OHLCV) data for instruments on Coinbase International Exchange | | **List loans assets** `coinbase_list_loans_assets` | Retrieve all assets available for loans from the Coinbase Exchange | | **List market products** `coinbase_list_market_products` | List market products from Coinbase Advanced Trade API | | **List product candles** `coinbase_list_product_candles` | Retrieve historical candlestick (OHLCV) data for a specific trading product on Coinbase | | **List products candles** `coinbase_list_products_candles` | Retrieve historical candlestick (OHLCV) data for a trading pair | | **List products stats** `coinbase_list_products_stats` | Get 24-hour statistics for a product on Coinbase Exchange | | **List products trades** `coinbase_list_products_trades` | Retrieve recent trades for a specific product from Coinbase Exchange API | | **List wallets** `coinbase_list_wallets` | Retrieve all wallets from Coinbase via the CDP SDK | | **List wrapped assets** `coinbase_list_wrapped_assets` | Retrieve all wrapped assets from Coinbase Exchange | ## Example prompts **Get Asset Details** > Pull the relevant data from Coinbase, summarize it in plain English, and point out anything that needs attention. **Get Exchange Currency** > Pull the relevant data from Coinbase, summarize it in plain English, and point out anything that needs attention. **Get Instrument Details** > Pull the relevant data from Coinbase, summarize it in plain English, and point out anything that needs attention. **Get Instruments Funding** > Pull the relevant data from Coinbase, 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 Coinbase working from chat. | | Manual | ClawLink | |---|---|---| | **Credential handling** | Collect, validate, store, and rotate the Coinbase API key yourself, then make sure every tool call uses the right account. | Users complete the hosted ClawLink setup once and the connected Coinbase 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 Coinbase. | 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 Coinbase actions to the runtime in a format your agent can reliably use. | 28 tools for Coinbase are already exposed through ClawLink, so the agent can read and act from chat immediately. | ## ClawLink vs. Composio Composio also exposes Coinbase 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 Coinbase in the browser, and the 28 tools above work from chat. There is no SDK and no config file, and the Coinbase 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 Coinbase 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 Coinbase tools Coinbase 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 Coinbase 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. ### Coinbase 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 Coinbase 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 Coinbase integration? Yes. ClawLink is the fastest way to connect Hermes to Coinbase: link your Coinbase account once in the browser and Hermes Agent can call the Coinbase API through 28 ready-made tools — no custom code or token handling. ### How do I connect Coinbase 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 Coinbase in the dashboard and Hermes can use it from the next message — no config files, and the Coinbase key you paste is stored server-side instead of in your environment. ### How long does it take to connect Coinbase to Hermes Agent? About two minutes. Sign in, click Connect next to Coinbase in the dashboard, authenticate, and Hermes Agent can use it from the next chat message. ### Why use ClawLink instead of wiring Coinbase 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 Coinbase working from chat. ### Hermes paired but still can't use Coinbase 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.
