# Delete Agent by Id

> Unregister an agent from Barndoor.

This removes the agent's registration but does not delete the underlying 
application directory. The agent can be re-registered using the same 
application_directory_id.




## OpenAPI

````yaml DELETE /api/agents/{agent_id}
openapi: 3.1.0
info:
  title: Barndoor Platform API
  version: 1.0.0
  description: >
    REST API for the Barndoor Platform - manage MCP servers, OAuth connections,
    and proxy MCP requests.


    ## Authentication


    All endpoints require a JWT Bearer token obtained through Barndoor's

    OAuth 2.0 authorization-code flow with PKCE. The SDK handles the OAuth

    flow automatically using interactive login.


    ## MCP Integration


    The `/mcp/{mcp_server_name}` endpoints provide streaming proxy access to
    third-party MCP servers

    (Salesforce, Notion, Slack, etc.) with automatic authentication and session
    management.

        The token should be included in the Authorization header:

        `Authorization: Bearer <your-jwt-token>`


        Use the Barndoor SDK's `loginInteractive()` function to obtain tokens
        automatically.
