Tools API

We’ve introduced a new Tools API, making it easier to integrate and manage custom tools programmatically.

What’s new

• HTTP Tools – External API integrations with templating & authentication.

  • URL templates with {{parameter}} substitution
  • Support for HTTP methods (GET, POST, PUT, DELETE, etc.)
  • Custom headers (including authentication)
  • Parameter definitions with types, descriptions, default values
  • Control over which parameters are visible to the LLM (send_to_model)

• Function Tools – Define tool schemas via API (same as in the UI).

  • OpenAPI-style schemas for custom business logic
  • Function name, description, parameters
  • Strict parameter validation
  • Optional manual approval before execution

• Code Tools (Python) – Run custom Python code in a secure sandbox.

  • Define parameters in JSON Schema
  • Access params variable for LLM-provided inputs
  • Supports return value processing & error handling
  • Fully isolated execution environment
