ScopeGate MCP server

ScopeGate

Never hand an AI agent a full OAuth scope again.

ScopeGate sits between your agents and the accounts they reach — yours or your clients'. You connect a service once, tick the exact actions an agent may call, and hand it an MCP endpoint that can do nothing else. Every call is logged; one click kills the key without touching the connection.

• Per-action permissions — gmail:reademails yes, gmail:sendemail no. Finer than any provider's OAuth scopes.
• Audit trail — who, which tool, what outcome, how long. Per project, exportable.
• One-click revocation — regenerate an endpoint key; the service connection stays.
• Tokens never leave — AES-256-GCM at rest, refreshed automatically, agents only ever see sg_….

Run it yourself in one command:

docker compose --profile local up

Open http://localhost:3000 — the admin login is printed in the container logs on first boot. Details in Quick Start.

Tech Stack

• Framework: Next.js 16 (App Router)
• Language: TypeScript
• Database: PostgreSQL + Prisma 7
• UI: Tailwind CSS v4, shadcn/ui
• Auth: Better Auth (database-backed sessions, Prisma adapter)
• MCP: @modelcontextprotocol/sdk (Streamable HTTP)
• Package Manager: pnpm

Quick Start (self-hosted)

Full feature parity with the hosted cloud version — nothing is cut for self-host.

git clone https://github.com/alifanov/scopegate.git
cd scopegate
docker compose --profile local up

Open http://localhost:3000. No .env file needed: a local Postgres and a fresh BETTERAUTHSECRET are provisioned automatically, and the generated admin login is printed once in the app container logs on first boot (look for Generated admin login) — search it with docker compose logs app | grep -A4 "First run". The password is also saved to the app_data volume so it survives restarts.

To connect real services (Gmail, LinkedIn, GitHub, …), copy .env.example to .env and fill in the OAuth client id/secret for the providers you want — every block is independent and optional, a provider without credentials simply doesn't show up.
