Unified MCP Server features
- Zero-storage architecture. Tool calls fetch data directly from source APIs; no data is cached or stored.
- Authorization-first access. All tools require explicit customer authorization before they become callable.
- Bi-directional actions. Agents can read and write data (e.g., update records) where the integration supports it.
- Unified auth handling. OAuth, API-key flows, token refresh and optional embedded sign-in UI are provided out of the box.
- Tool discovery controls. Scope available tools to fit model limits and reduce surface area.
- SDKs & language support. Client SDKs for TypeScript, Python, PHP, Java, C#, Ruby, Go and UI components for React, Vue, Angular, JS.
- Embedded security boundaries. Each connection defines isolated access, with read/write, object and action restrictions.
- Virtual & native webhooks. Unlimited webhook subscriptions with virtual polling for systems lacking native webhooks.
