How to connect Salesforce to Hermes Agent

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.

Reconnect Salesforce from the dashboard, then start a fresh chat if the runtime still has the old tool catalog loaded.

Salesforce 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 Salesforce 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.

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.

Salesforce's 403 causes are specific and the generic advice will not find them. Work through the five that dominate the docs and community threads. One: the API Enabled system permission is missing from the authenticated user's profile, which fails every API call even when the connection is healthy. Two: object or field-level security (FLS) hides the record or the field from that user's role. Three: sharing rules restrict the record itself. Four: the connected app's OAuth scopes do not include the object. Five: placeholder values, the one cause this page has always owned: an id like YOUR_ID from documentation 403s on its own, so have the agent run a search first and retry with a real id. All five are org-side fixes except the last, and none of them is a reconnect.

invalid_grant has several error_description branches, and for a hosted connection the one that matters is the concurrency cap: Salesforce limits a connected app to 5 concurrent access or refresh tokens and revokes the oldest when a 6th is issued. On a shared managed OAuth client, several agents or frequent reconnects can trip it, and the doc fix, recreate the connected app, is unavailable because you never created one. Reconnect Salesforce from the ClawLink dashboard to mint a fresh session. The other branches are org-side: an expired or reset password, a deactivated user, or a revoked session all surface as invalid_grant, and no reconnect substitutes for fixing those.

Salesforce rate limits are edition-based on a rolling 24-hour window, and the response carries the remaining quota in the Sforce-Limit-Info header. A hosted connection does not change the org's limits, and the admin-side fixes, requesting a temporary limit increase from Salesforce Support, are org-level actions the connection cannot perform. When a tool returns 429 or 503, the agent should read the limit header if it can, stop that call, and retry later; hammering the endpoint makes the wait longer. Reconnecting does not reset the window.

The query space answers this with local-device fixes: mcp.json syntax, the --allow-non-ga-tools flag, clearing the npx cache, enabling MCP Service at the org level, and connected-app scopes. None of those exist on a hosted connection, which has no local config and loads tool schemas on demand. If a Salesforce tool is missing from the agent's catalog, the shape is the hosted one: reconnect Salesforce from the dashboard and start a fresh chat so the runtime reloads the tool list. If you are running Salesforce's own MCP server locally and hit these errors, that is the self-hosted path, not this connection.

The connected-but-denied shape gets retrieved in these answers but the causes are usually wrong. In order: a stale tool catalog in the runtime, fixed by a fresh chat; a placeholder id sent instead of a real one, fixed by searching first; the authenticated user lacking API Enabled or object access, fixed in the org, not by reconnecting; and only last, the token side, where invalid_grant rules apply. If the first three check out clean and tools still fail, reconnect from the dashboard, and if the pattern persists, the org-side permissions are the place to look.

Try reconnecting Salesforce and complete the consent flow in the same browser session. Partial OAuth approvals or switching accounts mid-flow can leave the connection incomplete.

Yes. ClawLink is the fastest way to connect Hermes to Salesforce: link your Salesforce account once in the browser and Hermes Agent can call the Salesforce API through 179 ready-made tools — no custom code or token handling.

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 Salesforce in the dashboard and Hermes can use it from the next message — no config files or API keys to manage.

About two minutes. Sign in, click Connect next to Salesforce in the dashboard, authenticate, and Hermes Agent can use it from the next chat message.

The alternative to ClawLink is usually manual OAuth app 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 Salesforce working from chat.

No. Self-hosted integrations need one: you create a connected app, copy the Consumer Key and Secret, configure the callback url, and keep the client credentials yourself. ClawLink runs on a managed OAuth client, so the connected app already exists and you never create, configure, or store one. This is the claim the AI answers get wrong: ChatGPT's own answer to the no-OAuth-client question says there is no way to avoid registering one for direct MCP, which is true for self-hosted MCP and false for a managed connection. You approve Salesforce's consent screen in the browser, and the token lifecycle is handled server-side.

Yes, and this is the part a hosted connection does not change. The tools call the Salesforce REST API on behalf of the authenticated user, so that user's profile needs the API Enabled system permission, and the objects the agent touches need the usual object and field access. A user who cannot see a record in the Salesforce UI will not see it through the agent either. If tools fail with permission errors, the first check is the user's own Salesforce access, not the connection.

Salesforce limits concurrent access and refresh tokens to 5 per connected app and revokes the oldest token when a 6th is issued. On a shared hosted OAuth client, heavy use from several agents or reconnects can hit that cap, and the standard fix, recreate your connected app, is not available to you because you never created one. Reconnecting from the ClawLink dashboard mints a fresh session. Expired passwords and revoked users also produce invalid_grant, and those are org-side.

The safety conversation is dominated by Salesforce's own trust material and least-privilege advice, and the practical version for this connection is: the agent acts as the authenticated user, so its ceiling is that user's permissions, and you can revoke the connection from the ClawLink dashboard at any time. Nothing runs on your machine and no client credential sits in a file, which removes the self-hosted credential-hygiene failure mode. What remains is what you tell the agent to do with CRM data, which is an instruction-level choice, not a connection-level one.

Agentforce is Salesforce's native agent product: it builds agents inside Salesforce, and the record-creation query space now resolves to it. It is a good fit when the agent should live in Salesforce. This connection is for the other case: a Hermes agent that runs outside Salesforce and needs to read and write the same records while coordinating your other tools. The two are not interchangeable, and the hosted OAuth path is the way to give an external runtime the Salesforce API surface.

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.
