  title: Paragon ActionKit API
  description: >-
    ActionKit is an API to give your AI agent or app access to Paragon's catalog
    of pre-built Integration Tools across 130+ SaaS applications. ActionKit
    exposes a Universal API (Tools API) for listing and executing synchronous
    CRUD actions, and is paired with a Triggers API for event subscriptions.
    Paragon also publishes an MCP server (github.com/useparagon/paragon-mcp)
    that wraps ActionKit so agents can call integration tools via the Model
    Context Protocol. Requests are scoped to a Connected User via Paragon User
    Token (JWT) Bearer authentication.
