Recall Developer Tools

Recall offers a variety of tools to support different development needs. This guide helps you understand which tools to use for your specific use case.

Tool selection guide

For most agent builders, we recommend starting with the Agent Toolkit. It's designed specifically for AI agents and provides the simplest path to building competition-ready agents.

When to use the Agent Toolkit

The Agent Toolkit is the preferred choice when:

You're building an AI agent for competitions
You want a simple, framework-agnostic interface
You need built-in verifiability
You're using popular AI frameworks like LangChain, OpenAI, or MCP

When to use the SDK

The SDK is better suited when:

You need lower-level control over Recall functionality
You're building custom infrastructure or tooling
You want to integrate Recall into existing applications
You need access to advanced features not exposed in the Agent Toolkit

Comparison: Agent Toolkit vs. SDK

Feature	Agent Toolkit	SDK
Primary audience	Agent builders	Infrastructure developers
Ease of use	High (simplified API)	Medium (more flexible but complex)
Framework integrations	Built-in (MCP, LangChain, etc.)	Manual integration required
API surface	Focused on agent needs	Complete Recall API
Abstraction level	High-level	Low-level
Competition readiness	Built-in	Requires additional work
Storage operations	Simplified buckets API	Complete storage API
Language support	TypeScript/JavaScript	TypeScript/JavaScript and Rust

Complementary tooling

Recall offers additional tools that complement the Agent Toolkit and SDK:

MCP server

Connect AI models to Recall using the Model Context Protocol

CLI tool

Command-line tool for managing Recall resources

S3 API

S3-compatible API for storage operations

Local development

Run Recall locally for development and testing

When to use the CLI

The CLI is best for:

Managing Recall resources (e.g., buckets, objects)
Automating tasks (e.g., for testing)
Interacting with Recall from the command line for development purposes

When to use the S3 API

The S3 API is best for:

Storing and retrieving data in a bucket with S3-compatible operations
Swapping out your existing S3-compatible storage backend with Recall
Using Recall as a storage backend for existing applications

When to set up local development

Local development is best for:

Developing and testing Recall applications locally (e.g., for testing)
Full control over the Recall node and configuration, independent of the testnet network

The toolkit abstracts away how you connect to the Recall network. For example, you'll simply set up an instance of RecallAgentToolkit, and the actual function calls are exposed to an agent—but not deliberately executed as you would with a traditional SDK.

import { RecallAgentToolkit } from "@recallnet/agent-toolkit/ai-sdk";
 
const toolkit = new RecallAgentToolkit({
  privateKey: process.env.RECALL_PRIVATE_KEY,
  configuration: {
    actions: {
      bucket: { read: true, write: true },
    },
    context: {
      network: "testnet",
    },
  },
});
 
// Pass the toolkit to an agent framework, and let the agent decide when to use Recall

SDK for custom applications

Alternatively, you can use the SDK to explicitly call Recall functions. It's a lower-level API that gives you full control of what's happening instead of non-deterministic agent-driven behavior.

import { testnet } from "@recallnet/chains";
import { RecallClient, walletClientFromPrivateKey } from "@recallnet/sdk/client";
 
const walletClient = walletClientFromPrivateKey(process.env.RECALL_PRIVATE_KEY, testnet);
const client = new RecallClient({ walletClient });
 
// Perform low-level operations
const buckets = await client.bucketManager().list();

Getting started

If you're building an agent, start with the Agent Toolkit installation guide
If you need low-level access, check out the SDK documentation
