Agent Toolbox

What is Agent Toolbox?

Agent Toolbox is an MCP server and API that provides 13 production-ready tools for AI agents, such as web search, weather, finance, translation, and PDF extraction. It requires a single API key instead of multiple provider keys, and offers consistent JSON responses and built-in rate limiting. It is for developers building agents that need to interact with the real world.

How to use Agent Toolbox?

Get a free API key via a curl request, then send HTTP POST requests to the API endpoints (e.g., /v1/search) with Bearer auth. For MCP support, install the npm package agent-toolbox-mcp and add it to your MCP client configuration (e.g., Claude Desktop, Cursor, or Windsurf). Python SDKs for LangChain and LlamaIndex are also available.

FAQ from Agent Toolbox

What exactly does Agent Toolbox provide?

It is an MCP server and REST API bundling 13 tools (search, extract, screenshot, weather, finance, validate‑email, translate, geoip, news, whois, dns, pdf‑extract, qr) under one key.

How do I get started quickly?

Register via curl to obtain a free API key, then call any endpoint with a Bearer token. For MCP, install the npm package and add it to your client’s MCP servers config.

Are there any runtime dependencies?

The hosted API has no local dependencies beyond the ability to make HTTP requests. The MCP server requires Node.js. The Python SDKs (LangChain, LlamaIndex) require a Python environment with those libraries.

Where does my data live?

When using the hosted API, data is processed on the Agent Toolbox servers. Self‑hosting places all data on your own infrastructure.

What are the transport and authentication methods?

The server communicates via HTTP (REST) or the MCP protocol. Authentication uses a Bearer token in the Authorization header.
