Hermes + Brex
Hermes runs the task; the Brex connector supplies only the operations and resources allowed by the account you authorize. The Composer selects Hermes, asks for Brex access before sending, and keeps both choices in one task draft.
How the combination works
Hermes plans and executes. Brex supplies authorized app access.
Hermes coordinates a general-purpose agent loop across research, files, shell commands, and the tools enabled for the task.
Payments, Deposits, Cards
Hermes
Owns the task loop, model calls, cloud computer, tool choices, progress and final result.
Brex connector
Supplies the currently exposed operations for the authorized Brex account. It does not promise every feature in the Brex product.
Permission boundary
The connected identity, granted provider scopes, organization policy, resource sharing and the task's explicit instruction all constrain what Hermes can do.
Setup and first task
Connect one Brex account and verify one known resource.
The Composer preselects Hermes with DeepSeek V4 Pro. Start read-only when possible, then expand to write operations only after the account and resource boundary are clear.
Open the Hermes Composer
The Composer above carries Hermes, DeepSeek V4 Pro, and Brex. Add a precise target and expected result; the draft stays on this page during sign-in or connector authorization.
Authorize the intended Brex account
Review the Brex account, workspace and permissions on the authorization screen. Your organization's policies or administrator approval may limit which resources the connection can access.
Run and verify a bounded task
Name one Brex resource you can already access and ask the agent to check whether a read operation is available. If it is, retrieve and summarize that resource without changing it. If it is not, ask the agent to explain the missing operation or permission. Open the same resource in Brex and compare it with the agent's result. Check the account, resource identifier and current content before using the output for another task.
Access, cost and limits
What to verify before scaling Hermes + Brex
Research and operational work that needs a flexible tool-using agent rather than a repository-specific coding interface.
Establish with the first run
- Hermes and DeepSeek V4 Pro remain selected after sign-in.
- Brex shows the intended connected account before the task is sent.
- The returned data matches one known source resource, with write actions excluded until separately authorized.
Still depends on your setup
- A catalog listing does not guarantee every Brex website feature is available as an agent operation.
- OAuth scopes do not replace organization policy, resource sharing or a precise task instruction.
- Total task cost can include model tokens, active computer time, paid tools, connectors and the provider's own plan or quota.
Verification and recovery
Check Brex itself before trusting the result.
Open the same resource in Brex and compare it with the agent's result. Check the account, resource identifier and current content before using the output for another task.
Connection troubleshooting
If Brex access fails, check the connected identity, resource sharing and requested permissions. Reconnect an expired or revoked account in connector settings. If the connection is healthy but an operation is unavailable, changing accounts may not resolve it.
Writes need explicit scope
Name the target record and exact allowed change. A request to summarize, analyze or draft does not authorize sending, publishing or deleting.
Re-check current state
For decisions or follow-up writes, open the resource in Brex and check its current state. A successful earlier read may already be stale.
