Features

Connectivity, not optimization.

Nerb is a credential broker and API gateway. The intelligence lives in your LLM. We provide authenticated, safe, hosted access to your platforms' APIs, and stay out of the way.

OAuth broker

One connect. We handle the plumbing.

Connect a platform once and Nerb hands back an MCP URL and a Bearer token. Credentials are encrypted at rest and rotated automatically. You don't touch any of the per-platform API setup — for any platform you add.

Unified context

Every platform. One MCP server.

Correlate paid spend across networks with on-site conversions and organic queries in the same conversation. Your LLM stitches the picture; you don't stitch one integration per platform.

Safe writes

Draft → preview → confirm.

The LLM proposes mutations, we render the planned operations and projected impact, you confirm. New campaigns ship paused. Daily budget caps and double-confirmation are configurable per account.

Every call logged. Every dollar capped.

Per-account daily budget caps, immutable audit log, kill-switch per tenant. Export to CSV or JSONL. Built for the day someone asks "who told the LLM to do that?"

Google's server is read-only, Gemini-leaning, Google-only, and asks you to bring your own back-end setup. Nerb is hosted, spans every platform you run on, supports safe writes, and works across every MCP client.
For each platform we store an OAuth refresh token (or equivalent API credential), encrypted at rest. We never see your password. Revoke access from the platform — for Google, at myaccount.google.com/permissions — and we get an invalid_grant on next refresh.
No. Writes go through draft → preview → confirm. New campaigns ship paused. You set a per-account daily budget cap. Nerb blocks any confirm that exceeds it. There's also a per-tenant kill-switch.
All, we serve a single streamable-HTTP endpoint with bearer auth, bring whatever client you like.
Paid spend, on-site behavior, and organic queries are the same question asked different ways. Putting every platform behind one MCP endpoint lets your LLM answer “are we paying for traffic we’d get organically?” without juggling a separate integration per platform.
Flat $9 per connected account per month. Free for your first connected account (read-only). No per-API-call fees, no per-seat fees, no managed-spend tiers.
Nerb processes ad data and search terms, not PHI. We don't sign BAAs and our ToS explicitly prohibits passing PHI through the gateway.
Yes. We sign a service-provider DPA on request for any paid plan. We don't sell or share data, don't combine across customers, and delete on instruction.
