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 Google's APIs, and stay out of the way.

One sign-in. We handle the plumbing.

Sign in with Google once and Nerb hands back an MCP URL and a Bearer token. Refresh tokens are encrypted at rest and rotated automatically. You don't touch any of the back-end Google setup.

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.

Unified context

Ads, GA4, and Search Console. One MCP server.

Correlate paid spend with on-site conversions and organic queries in the same conversation. Your LLM stitches the picture; you don't stitch three integrations.

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?"

FAQ

Questions, answered.

Google's server is read-only, Gemini-leaning, and asks you to bring your own back-end setup. Nerb is hosted, supports safe writes, and works across every MCP client.
We store an OAuth refresh token, encrypted at rest. We never see your password. Revoke access 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 three ways. Bundling them lets your LLM answer 'are we paying for traffic we'd get organically?' without juggling three integrations.
Flat $8 per connected account per month. Free for the first accounts (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.
