Paragon Permissions API

info:
  title: Paragon ActionKit Credentials Permissions 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.
