Howlin Wolf Applications
Agents never hold long-lived SaaS secrets.
Your tools run through a broker that injects credentials at the boundary — with audit, revoke, and no keys in the model.
Built for the default mess: keys pasted into agent configs and prompts — not a dig at other brokers.
How it works
Operator session (Auth0), server control plane (bk_*), and agent runtime (broker JWT).
Connect SaaS accounts
Operators sign in with Auth0 and connect GitHub via OAuth. Tokens stay encrypted in CallVault; agents get connection handles only.
Mint broker JWTs server-side
Your backend uses a bk_test_* or bk_live_* control key to call POST /v1/broker/token and passes only the short-lived JWT to the agent runtime.
Execute tools
Agents call POST /v1/tools/execute with the broker JWT and a connected_account_id. Results return — secrets do not.
Product proof
Credentials at the boundary
OAuth tokens and control keys stay in CallVault and your server. Agents receive short-lived broker JWTs scoped to tenant, agent app, and environment.
Policy + approvals
Low-risk tools run automatically. High-risk calls pause for operator approval before the broker continues the invocation.
Audit and revoke
Tool executions are metered and logged per invocation — built for teams that need visibility without pasting keys into prompts.
Transparent tiers
Usage is billed on tool executions (not OAuth connects). Plans from Free through Scale, with front-of-house plan match when usage crosses the next tier.
Pricing
Metered on tool executions. Free tier includes 5k calls per month.
| Tier | Price | Included calls | Overage |
|---|---|---|---|
| Free | $0 | 5k | — |
| Starter | $49 | 55k | $0.0006 |
| Growth | $89 | 110k | $0.0005 |
| Pro | $139 | 275k | $0.0004 |
| Scale | $239 | 550k | $0.00035 |
| Enterprise | Contact sales | custom (1.1M+) | no public $ |
Plan match FAQ
- What if my usage crosses the next plan?
- If usage crosses the next plan, we may apply a one-time plan match (bill the next plan’s price that month). Once per account per plan. After that: standard plan billing (base + overage) and we show Upgrade savings available.
