Gentkey
One MCP URL for all your connectors.
Connect your accounts once at gentkey.com. Every AI surface — claude.ai (web & mobile), Claude Code, Cursor, any MCP client — reaches all of them through a single OAuth-protected MCP endpoint:
https://app.gentkey.com/mcp
Providers give an agent a key to the whole house. Gentkey cuts it a key to one room — and you can take it back at any time.
Why
Connectors are a commodity; turning a coarse OAuth token into scoped, revocable, auditable capabilities is the point:
- Capability-scoped writes. Read tools work out of the box (switchable off per connection). Write tools require an explicit capability grant you make in the dashboard.
- Enforced constraints. Grants are bounded per call (e.g. max $50 budget delta) and per rolling window (writes / targets / dollars per hour or day).
- Dry runs. Every write tool advertises a
dry_runflag that reports exactly what the real call would do — including the policy verdict, even before a grant exists — with no side effects. - Full audit trail. Every decision is recorded (allowed / denied / constraint-denied / dry-run) with a human-readable plan summary — "Change 'Summer Sale' budget: $50 → $80", not
grant:abc. - Server-side credentials. Upstream credentials are encrypted at rest (AES-256-GCM, AAD-bound; optional Cloud KMS envelope encryption) and injected server-side. The model never sees them.
Connect a client
Create an account at app.gentkey.com, connect your services, then point your client at the endpoint. Authentication is OAuth 2.0 with dynamic client registration — no API keys to paste.
claude.ai (web & mobile) — Settings → Connectors → Add custom connector → https://app.gentkey.com/mcp
Claude Code
claude mcp add --transport http gentkey https://app.gentkey.com/mcp
Cursor — add to ~/.cursor/mcp.json:
{ "mcpServers": { "gentkey": { "url": "https://app.gentkey.com/mcp" } } }
Any other client that speaks Streamable HTTP with OAuth works the same way.
What you can connect
- Native connectors with deep, semantic constraints: Google Ads (operation-typed capability grants, dollar caps on budget changes), Meta Ads (currency-aware budget deltas, dry-run plan/commit), BigQuery (statement-typed grants), Apple Search Ads, App Store Connect, Google Search Console, RevenueCat, and Superwall (per-resource capability maps).
- A directory of 1,798 services reachable by MCP passthrough, OpenAPI, or GraphQL — Notion, Linear, Slack, Stripe, Figma, Canva, Atlassian, HubSpot, Supabase, Sentry, and more. Upstream tools are proxied verbatim (schemas included) but default to write-gated: only curated read tools run without a grant, and every call is audited either way.
