  description: >-
    **Flowra** is an AI-powered platform for building agents, workflows, and
    integrations.


    ### Capabilities

    - **Tools & Toolkits** – Define and group tools for agents and workflows.

    - **Workflows** – Orchestrate steps and automate processes.

    - **Triggers** – Schedule or event-based execution.

    - **Auth & Connections** – OAuth, API keys, and connected accounts.

    - **MCP** – Model Context Protocol server integration.

    - **Knowledge / RAG** – Add files and URLs for retrieval-augmented
    generation.


    ### Authentication

    Use the **x-api-key** header with a project API key to access endpoints that
    support API Key auth. Create and manage API keys in the dashboard under your
    project settings.


    Only endpoints that support API Key authentication via the @ApiKeyEnabled()
    decorator.


    Send x-api-key (required). On multi-tenant endpoints, optionally send
    x-username to act as an external user.
