Corsair features
- Unified integration syntax. Expose all supported services through a single, consistent API regardless of each provider's OAuth flow.
- Self-hosted SDK. Run the full integration stack on your own infrastructure with no per-seat fees.
- Managed permissions. Set permission modes per integration; destructive actions require explicit user approval.
- Caching & rate-limit handling. Data is cached via webhooks and polling, reducing API calls and handling rate limits automatically.
- Open source plugins. Add or customize integrations by opening a PR or forking the TypeScript repo.
- MCP compatibility. Plugs directly into Model Context Protocol-compatible agent frameworks or can be exposed as an MCP server.
WunderGraph features
- Connect any service. Expose gRPC, Kafka, NATS or Redis services through a unified GraphQL router without extra infrastructure.
- Real-time streams. Router handles subscriptions, aggregating events from Kafka, NATS or Redis and pushes updates to clients.
- MCP Gateway. One gateway turns approved operations into agent-ready tools with built-in authentication, eliminating separate MCP servers.
- Graph governance hub. Shared canvas for schema design, review, ownership, proposals and safe deployments with audit logs and RBAC.
- Cache warming. Pre-warm query planning cache to eliminate long planning delays for high-load scenarios.
