Gentkey MCP Server

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_run flag 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 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), BigQuery (statement-typed grants), Apple Search Ads, App Store Connect, and Google Search Console.
• A directory of 1,700+ services reachable by MCP passthrough, OpenAPI, or GraphQL — Notion, Linear, Slack, Stripe, Figma, Canva, Atlassian, HubSpot, Supabase, Sentry, RevenueCat, Superwall, 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.

About this repository

Gentkey's source is proprietary. This repository hosts the public documentation, the MCP registry manifest (server.json), and the issue tracker — bug reports, questions, and connector requests are welcome in Issues.
