# How to connect Stack Ai to Hermes Agent (paste one key, 22 tools) > Connect Stack Ai to Hermes with ClawLink: paste your Stack Ai key once and 22 tools work from chat. No MCP server to run, nothing stored on your machine. Web version: https://claw-link.dev/hermes/stack-ai Most guides for giving Hermes Agent Stack Ai 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 Stack Ai setup: pair once in the browser and your always-on Hermes agent can act on Stack Ai 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 Stack Ai. 1. **Install ClawLink** — add the plugin to Hermes Agent once. 2. **Connect Stack Ai** — 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 stack-ai # connect Stack Ai (browser OAuth) npx -y @useclawlink/cli actions stack-ai # list available actions npx -y @useclawlink/cli run stack-ai --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 Stack Ai in the [ClawLink dashboard](https://claw-link.dev/dashboard) — paste your Stack Ai API key once. Verify the connection by asking Hermes: > Use Stack Ai to check health 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 Stack Ai is connected in the dashboard, that agent calls the same 22 Stack Ai tools over MCP.

ClawLink connects Stack Ai to Hermes Agent and exposes 22 Stack Ai 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 Stack Ai integration](https://claw-link.dev/openclaw/stack-ai) works the same way. ## What the Hermes Agent Stack Ai integration can do 22 Stack Ai tools are ready for Hermes Agent once the account is connected. ### All 22 Stack Ai tools for Hermes | Tool | What it does | |---|---| | **Check health** `stack_ai_check_health` | Check the health status of the Stack AI API | | **Get action inputs** `stack_ai_get_action_inputs` | Retrieve the input schema for a specific provider action in Stack AI | | **Get action outputs** `stack_ai_get_action_outputs` | Retrieve the output parameters schema for a Stack.ai provider action as JSON schema | | **Get connector type schema** `stack_ai_get_connector_type_schema` | Retrieve the configuration schema for a specific connector type in Stack AI | | **Get license status** `stack_ai_get_license_status` | Retrieve the current Stack AI license status | | **Get provider** `stack_ai_get_provider` | Retrieve details of a specific Stack AI tool provider | | **Get provider action** `stack_ai_get_provider_action` | Get details of a specific action for a provider | | **Get provider icon** `stack_ai_get_provider_icon` | Fetch a provider icon image by provider identifier | | **Get provider trigger** `stack_ai_get_provider_trigger` | Retrieve detailed information about a specific trigger for a provider | | **Get root** `stack_ai_get_root` | Retrieve information from the Stack AI API root endpoint | | **Get trigger by provider** `stack_ai_get_trigger_by_provider` | Retrieve detailed information about a specific trigger from a provider | | **Get trigger inputs** `stack_ai_get_trigger_inputs` | Retrieve the input parameters for a trigger as a JSON schema | | **Get trigger outputs** `stack_ai_get_trigger_outputs` | Retrieve the output schema for a specific trigger in Stack AI | | **List connector types** `stack_ai_list_connector_types` | List all available connector types from Stack AI | | **List integrations** `stack_ai_list_integrations` | List all available Stack AI integrations | | **List permission groups** `stack_ai_list_permission_groups` | List all permission groups with their associated permissions | | **List permissions** `stack_ai_list_permissions` | List all available permissions in Stack AI | | **List provider triggers** `stack_ai_list_provider_triggers` | Get all available triggers for a specific provider | | **List stack AI triggers** `stack_ai_list_stack_ai_triggers` | List all available Stack AI tool triggers | | **List stackai actions** `stack_ai_list_stackai_actions` | List all available Stack AI tool actions | | **List stackai providers** `stack_ai_list_stackai_providers` | List all Stack AI tool providers (integrations) | | **List stackai tools** `stack_ai_list_stackai_tools` | List all Stack AI built-in tools | ## Example prompts **Check Health** > Use Stack Ai to check health and walk me through the result in plain English. **Get Action Inputs** > Pull the relevant data from Stack Ai, summarize it in plain English, and point out anything that needs attention. **Get Action Outputs** > Pull the relevant data from Stack Ai, summarize it in plain English, and point out anything that needs attention. **Get Connector Type Schema** > Pull the relevant data from Stack Ai, 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 Stack Ai working from chat. | | Manual | ClawLink | |---|---|---| | **Credential handling** | Collect, validate, store, and rotate the Stack Ai API key yourself, then make sure every tool call uses the right account. | Users complete the hosted ClawLink setup once and the connected Stack Ai 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 Stack Ai. | 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 Stack Ai actions to the runtime in a format your agent can reliably use. | 22 tools for Stack Ai are already exposed through ClawLink, so the agent can read and act from chat immediately. | ## ClawLink vs. Composio Composio also exposes Stack Ai 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 Stack Ai in the browser, and the 22 tools above work from chat. There is no SDK and no config file, and the Stack Ai key you paste at setup is stored server-side rather than kept in your environment. Choosing between them? Read the full [Composio alternatives](https://claw-link.dev/hub/composio-alternatives) comparison. ### Hermes paired but still can't use Stack Ai 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`. ### Connection succeeds but no tools appear Reconnect Stack Ai 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 Stack Ai tools Stack Ai 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 Stack Ai 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. ### Stack Ai 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 Stack Ai 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 Stack Ai integration? Yes. ClawLink is the fastest way to connect Hermes to Stack Ai: link your Stack Ai account once in the browser and Hermes Agent can call the Stack Ai API through 22 ready-made tools — no custom code or token handling. ### How do I connect Stack Ai 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 Stack Ai in the dashboard and Hermes can use it from the next message — no config files, and the Stack Ai key you paste is stored server-side instead of in your environment. ### How long does it take to connect Stack Ai to Hermes Agent? About two minutes. Sign in, click Connect next to Stack Ai in the dashboard, authenticate, and Hermes Agent can use it from the next chat message. ### Why use ClawLink instead of wiring Stack Ai 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 Stack Ai working from chat. ### Hermes paired but still can't use Stack Ai 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.
