Built-in Tools — Rabbit Agent SDK

The SDK includes several pre-built tools ready to use out of the box.

FetchTool

Makes HTTP requests to REST APIs. The LLM can call this to fetch data from any URL.

typescript

import { Agent, OpenAIProvider, FetchTool } from "@rabbit-agent-sdk/rabbit-agent-sdk";
 
const fetchTool = new FetchTool();
 
const agent = new Agent({
  provider: new OpenAIProvider(),
  tools: [fetchTool],
  systemPrompt: "You can fetch data from APIs. Use the FetchTool when asked.",
});
 
await agent.run("Fetch the latest posts from https://jsonplaceholder.typicode.com/posts?_limit=3");

FetchTool Schema:

Parameter	Type	Required	Description
`url`	`string` (URL)	Yes	The URL to fetch
`method`	`"GET", "POST", "PUT", "DELETE"`	No	HTTP method (default: GET)
`headers`	`Record<string, string>`	No	HTTP headers as key-value pairs
`body`	`string`	No	Request body (for POST/PUT)

WebSearchTool

Searches the web using the Tavily API. Falls back to a mock response if no API key is provided.

typescript

import { Agent, OpenAIProvider, WebSearchTool } from "@rabbit-agent-sdk/rabbit-agent-sdk";
 
// With a real API key
const searchTool = new WebSearchTool(process.env.TAVILY_API_KEY);
 
// Without an API key (returns mock results)
const mockSearchTool = new WebSearchTool();
 
const agent = new Agent({
  provider: new OpenAIProvider(),
  tools: [searchTool],
  systemPrompt: "Search the web when asked about current events.",
});
 
await agent.run("What are the latest developments in AI?");

WebSearchTool Schema:

Parameter	Type	Required	Description
