Granular permission gateway for MCP agents. Per-agent scopes for Google Drive, Gmail, Calendar.
ScopeGate MCP server exists for a simple reason — assistants are far more useful when they can act on ScopeGate directly instead of describing what you should do. Granular permission gateway for MCP agents. Per-agent scopes for Google Drive, Gmail, Calendar.
AI Access Proxy Layer. Connect external services (e.g. Google), define granular permissions, and receive an MCP endpoint URL for use in AI agents. Acts as a permission gateway — exposing only the specific capabilities you authorize, more granular than native OAuth scopes.
Once ScopeGate is connected, these are the calls the assistant has available:
Framework — Next.js 16 (App Router)Language — TypeScriptDatabase — PostgreSQL + Prisma 7Auth — Better Auth (database-backed sessions, Prisma adapter)MCP — @modelcontextprotocol/sdk (Streamable HTTP)pnpm — PostgreSQLUser — authentication, team membershipSession — database-backed auth sessionsAccount — auth provider credentials (email/password)Project — logical grouping for services and endpointsTeamMember — user-project relationship with roles (owner/member)ServiceConnection — OAuth tokens for connected servicesSetup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client.
You will need 3 environment variables: DATABASE_URL, BETTER_AUTH_SECRET, BETTER_AUTH_URL. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
Among the database access options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. ScopeGate's toolset — Framework, Language, Database and 11 more — is a fair guide to whether it matches your workflow. It is maintained by alifanov; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
