# How to connect Daffy to Hermes Agent (paste one key, 12 tools) > Connect Daffy to Hermes with ClawLink: paste your Daffy key once and 12 tools work from chat. No MCP server to run, nothing stored on your machine. Web version: https://claw-link.dev/hermes/daffy Most guides for giving Hermes Agent Daffy 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 Daffy setup: pair once in the browser and your always-on Hermes agent can act on Daffy 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 Daffy. 1. **Install ClawLink** — add the plugin to Hermes Agent once. 2. **Connect Daffy** — 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 daffy # connect Daffy (browser OAuth) npx -y @useclawlink/cli actions daffy # list available actions npx -y @useclawlink/cli run daffy --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 Daffy in the [ClawLink dashboard](https://claw-link.dev/dashboard) — paste your Daffy API key once. Verify the connection by asking Hermes: > Pull the relevant data from Daffy, 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 Daffy is connected in the dashboard, that agent calls the same 12 Daffy tools over MCP.

ClawLink connects Daffy to Hermes Agent and exposes 12 Daffy 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 Daffy integration](https://claw-link.dev/openclaw/daffy) works the same way. ## What the Hermes Agent Daffy integration can do 12 Daffy tools are ready for Hermes Agent once the account is connected. ### All 12 Daffy tools for Hermes | Tool | What it does | |---|---| | **Get balance** `daffy_get_balance` | Retrieve the authenticated user's Daffy fund balance information | | **Get contributions** `daffy_get_contributions` | Retrieves paginated list of contributions made to the authenticated user's Daffy donor-advised | | **Get donations** `daffy_get_donations` | Retrieves the authenticated user's donation history from their Daffy account | | **Get gift by code** `daffy_get_gift_by_code` | Retrieve details of a specific gift by its unique code | | **Get gifts** `daffy_get_gifts` | Retrieve a paginated list of gifts associated with the user's Daffy account | | **Get non profit by ein2** `daffy_get_non_profit_by_ein2` | Retrieve detailed information about a non-profit organization by its EIN | | **Get user by username** `daffy_get_user_by_username` | Retrieve a user's public profile information by username | | **Get user causes** `daffy_get_user_causes` | Retrieves the list of charitable causes associated with a user's Daffy fund | | **Get user donations** `daffy_get_user_donations` | Retrieve public donations for a specific user by user ID | | **Get user profile** `daffy_get_user_profile` | Retrieve the authenticated user's profile | | **Search non profits** `daffy_search_non_profits` | Search non-profit organizations by cause ID and query text | | **Create gift** `daffy_create_gift` | Create a new charitable gift | ## Example prompts **Get Balance** > Pull the relevant data from Daffy, summarize it in plain English, and point out anything that needs attention. **Get Contributions** > Pull the relevant data from Daffy, summarize it in plain English, and point out anything that needs attention. **Get Donations** > Pull the relevant data from Daffy, summarize it in plain English, and point out anything that needs attention. **Get Gift By Code** > Pull the relevant data from Daffy, 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 Daffy working from chat. | | Manual | ClawLink | |---|---|---| | **Credential handling** | Collect, validate, store, and rotate the Daffy API key yourself, then make sure every tool call uses the right account. | Users complete the hosted ClawLink setup once and the connected Daffy 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 Daffy. | 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 Daffy actions to the runtime in a format your agent can reliably use. | 12 tools for Daffy are already exposed through ClawLink, so the agent can read and act from chat immediately. | ## ClawLink vs. Composio Composio also exposes Daffy 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 Daffy in the browser, and the 12 tools above work from chat. There is no SDK and no config file, and the Daffy 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 Daffy 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 Daffy tools Daffy 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 Daffy 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. ### Daffy 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 Daffy 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 Daffy integration? Yes. ClawLink is the fastest way to connect Hermes to Daffy: link your Daffy account once in the browser and Hermes Agent can call the Daffy API through 12 ready-made tools — no custom code or token handling. ### How do I connect Daffy 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 Daffy in the dashboard and Hermes can use it from the next message — no config files, and the Daffy key you paste is stored server-side instead of in your environment. ### How long does it take to connect Daffy to Hermes Agent? About two minutes. Sign in, click Connect next to Daffy in the dashboard, authenticate, and Hermes Agent can use it from the next chat message. ### Why use ClawLink instead of wiring Daffy 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 Daffy working from chat. ### Hermes paired but still can't use Daffy 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.
