# How to connect Weights & Biases to Hermes Agent (paste one key, 10 tools) > Connect Weights & Biases to Hermes with ClawLink: paste your Weights & Biases key once and 10 tools work from chat. No MCP server to run, nothing stored on your machine. Web version: https://claw-link.dev/hermes/weights-and-biases Most guides for giving Hermes Agent Weights & Biases 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 Weights & Biases setup: pair once in the browser and your always-on Hermes agent can act on Weights & Biases 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 Weights & Biases. 1. **Install ClawLink** — add the plugin to Hermes Agent once. 2. **Connect Weights & Biases** — 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 weights-and-biases # connect Weights & Biases (browser OAuth) npx -y @useclawlink/cli actions weights-and-biases # list available actions npx -y @useclawlink/cli run weights-and-biases --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 Weights & Biases in the [ClawLink dashboard](https://claw-link.dev/dashboard) — paste your Weights & Biases API key once. Verify the connection by asking Hermes: > Pull the relevant data from Weights & Biases, 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 Weights & Biases is connected in the dashboard, that agent calls the same 10 Weights & Biases tools over MCP.

ClawLink connects Weights & Biases to Hermes Agent and exposes 10 Weights & Biases 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 Weights & Biases integration](https://claw-link.dev/openclaw/weights-and-biases) works the same way. ## What the Hermes Agent Weights & Biases integration can do 10 Weights & Biases tools are ready for Hermes Agent once the account is connected. ### All 10 Weights & Biases tools for Hermes | Tool | What it does | |---|---| | **Get current viewer** `weights_and_biases_get_current_viewer` | Return the authenticated W&B user, default entity, and team names for connection context | | **Get organization** `weights_and_biases_get_organization` | Return a W&B organization's identifiers and organization entity by exact name | | **Get team** `weights_and_biases_get_team` | Return a W&B team's identity and bounded membership metadata by exact team entity name | | **List artifact types** `weights_and_biases_list_artifact_types` | Return one page of artifact types defined in a W&B project | | **List automations** `weights_and_biases_list_automations` | Return one page of W&B automations accessible under an entity | | **List integrations** `weights_and_biases_list_integrations` | List one page of Slack workspace/channel metadata and webhook integration names for a W&B entity | | **List projects** `weights_and_biases_list_projects` | Return one page of W&B projects visible under an entity | | **List reports** `weights_and_biases_list_reports` | Return one page of beta W&B reports for a project | | **List runs** `weights_and_biases_list_runs` | List one page of runs with IDs, display names, states, and creation times | | **List sweeps** `weights_and_biases_list_sweeps` | Return one page of hyperparameter sweeps from a W&B project when sweeps are enabled for the | ## Example prompts **Get Current Viewer** > Pull the relevant data from Weights & Biases, summarize it in plain English, and point out anything that needs attention. **Get Organization** > Pull the relevant data from Weights & Biases, summarize it in plain English, and point out anything that needs attention. **Get Team** > Pull the relevant data from Weights & Biases, summarize it in plain English, and point out anything that needs attention. **List Artifact Types** > List the relevant items in Weights & Biases, group them by priority, and recommend what Hermes should do next. ## 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 Weights & Biases working from chat. | | Manual | ClawLink | |---|---|---| | **Credential handling** | Collect, validate, store, and rotate the Weights & Biases API key yourself, then make sure every tool call uses the right account. | Users complete the hosted ClawLink setup once and the connected Weights & Biases 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 Weights & Biases. | 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 Weights & Biases actions to the runtime in a format your agent can reliably use. | 10 tools for Weights & Biases are already exposed through ClawLink, so the agent can read and act from chat immediately. | ## ClawLink vs. Composio Composio also exposes Weights & Biases 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 Weights & Biases in the browser, and the 10 tools above work from chat. There is no SDK and no config file, and the Weights & Biases 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 Weights & Biases 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 Weights & Biases tools Weights & Biases 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 Weights & Biases 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. ### Weights & Biases 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 Weights & Biases 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 Weights & Biases integration? Yes. ClawLink is the fastest way to connect Hermes to Weights & Biases: link your Weights & Biases account once in the browser and Hermes Agent can call the Weights & Biases API through 10 ready-made tools — no custom code or token handling. ### How do I connect Weights & Biases 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 Weights & Biases in the dashboard and Hermes can use it from the next message — no config files, and the Weights & Biases key you paste is stored server-side instead of in your environment. ### How long does it take to connect Weights & Biases to Hermes Agent? About two minutes. Sign in, click Connect next to Weights & Biases in the dashboard, authenticate, and Hermes Agent can use it from the next chat message. ### Why use ClawLink instead of wiring Weights & Biases 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 Weights & Biases working from chat. ### Hermes paired but still can't use Weights & Biases 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.
