# How to connect Neutrino to Hermes Agent (paste one key, 24 tools) > Connect Neutrino to Hermes with ClawLink: paste your Neutrino key once and 24 tools work from chat. No MCP server to run, nothing stored on your machine. Web version: https://claw-link.dev/hermes/neutrino Most guides for giving Hermes Agent Neutrino 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 Neutrino setup: pair once in the browser and your always-on Hermes agent can act on Neutrino 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 Neutrino. 1. **Install ClawLink** — add the plugin to Hermes Agent once. 2. **Connect Neutrino** — 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 neutrino # connect Neutrino (browser OAuth) npx -y @useclawlink/cli actions neutrino # list available actions npx -y @useclawlink/cli run neutrino --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 Neutrino in the [ClawLink dashboard](https://claw-link.dev/dashboard) — paste your Neutrino API key once. Verify the connection by asking Hermes: > Use Neutrino to add watermark to image 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 Neutrino is connected in the dashboard, that agent calls the same 24 Neutrino tools over MCP.

ClawLink connects Neutrino to Hermes Agent and exposes 24 Neutrino 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 Neutrino integration](https://claw-link.dev/openclaw/neutrino) works the same way. ## What the Hermes Agent Neutrino integration can do 24 Neutrino tools are ready for Hermes Agent once the account is connected. ### All 24 Neutrino tools for Hermes | Tool | What it does | |---|---| | **Add watermark to image** `neutrino_add_watermark_to_image` | Add a watermark to an image with customizable position, opacity, and output format | | **Bad word filter** `neutrino_bad_word_filter` | Detect bad words and profanity in text | | **Bin lookup** `neutrino_bin_lookup` | Perform a BIN (Bank Identification Number) lookup to retrieve comprehensive card issuer | | **Check ip blocklist** `neutrino_check_ip_blocklist` | Check if an IP address is on a blocklist | | **Convert** `neutrino_convert` | Perform unit and currency conversions | | **Email validate** `neutrino_email_validate` | Validates and analyzes email addresses for syntax, domain validity, DNS/MX records, and detects | | **Email verify** `neutrino_email_verify` | Verify and analyze the deliverability of an email address | | **Geocode address** `neutrino_geocode_address` | Geocode an address | | **Geocode reverse** `neutrino_geocode_reverse` | Convert geographic coordinates (latitude/longitude) into real-world address information | | **Hlr lookup** `neutrino_hlr_lookup` | Perform real-time HLR (Home Location Register) lookup to validate mobile numbers and retrieve | | **Host reputation** `neutrino_host_reputation` | Check if an IP address, domain, or URL is listed on DNS-based Blackhole Lists (DNSBLs) | | **HTML clean** `neutrino_html_clean` | Clean and sanitize untrusted HTML | | **HTML render** `neutrino_html_render` | Render HTML content to PDF, PNG, or JPG format | | **Image resize** `neutrino_image_resize` | Resize, crop, and convert images to PNG or JPG format | | **Ip info** `neutrino_ip_info` | Get comprehensive geolocation and network information for an IPv4 or IPv6 address | | **Ip probe** `neutrino_ip_probe` | Analyzes an IPv4 or IPv6 address to extract detailed network intelligence including | | **Lookup domain** `neutrino_lookup_domain` | Perform a domain lookup to retrieve WHOIS, DNS records, domain registration information and | | **Phone validate** `neutrino_phone_validate` | Validate and lookup phone numbers | | **Qr code** `neutrino_qr_code` | Generate a QR code or Code 128 barcode as a PNG image | | **Run browser bot** `neutrino_run_browser_bot` | Automate browser interactions using a real Chromium browser | | **Ua lookup** `neutrino_ua_lookup` | Parse and analyze User-Agent strings to extract detailed browser, device, and operating system | | **URL info** `neutrino_url_info` | Parse, analyze, and retrieve content from the supplied URL | | **Verify security code** `neutrino_verify_security_code` | Verify a security code generated by SMS Verify or Phone Verify APIs | | **Sms verify** `neutrino_sms_verify` | Send a unique security code via SMS | ## Example prompts **Add Watermark To Image** > Use Neutrino to add watermark to image and walk me through the result in plain English. **Bad Word Filter** > Use Neutrino to bad word filter and walk me through the result in plain English. **Bin Lookup** > Use Neutrino to bin lookup and walk me through the result in plain English. **Check Ip Blocklist** > Use Neutrino to check ip blocklist 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 Neutrino working from chat. | | Manual | ClawLink | |---|---|---| | **Credential handling** | Collect, validate, store, and rotate the Neutrino API key yourself, then make sure every tool call uses the right account. | Users complete the hosted ClawLink setup once and the connected Neutrino 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 Neutrino. | 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 Neutrino actions to the runtime in a format your agent can reliably use. | 24 tools for Neutrino are already exposed through ClawLink, so the agent can read and act from chat immediately. | ## ClawLink vs. Composio Composio also exposes Neutrino 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 Neutrino in the browser, and the 24 tools above work from chat. There is no SDK and no config file, and the Neutrino 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 Neutrino 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 Neutrino tools Neutrino 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 Neutrino 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. ### Neutrino 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 Neutrino 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 Neutrino integration? Yes. ClawLink is the fastest way to connect Hermes to Neutrino: link your Neutrino account once in the browser and Hermes Agent can call the Neutrino API through 24 ready-made tools — no custom code or token handling. ### How do I connect Neutrino 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 Neutrino in the dashboard and Hermes can use it from the next message — no config files, and the Neutrino key you paste is stored server-side instead of in your environment. ### How long does it take to connect Neutrino to Hermes Agent? About two minutes. Sign in, click Connect next to Neutrino in the dashboard, authenticate, and Hermes Agent can use it from the next chat message. ### Why use ClawLink instead of wiring Neutrino 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 Neutrino working from chat. ### Hermes paired but still can't use Neutrino 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.
