AI agents

mcp-agent

A Python framework for building AI agents that use tools through the Model Context Protocol.

New this week

What it does

mcp-agent helps programmers build AI agents: programs where an AI model can take actions, like reading files or fetching web pages. It is built around the Model Context Protocol (MCP), a common way to connect AI models to outside tools.

It handles connecting to these tool servers and includes ready-made patterns for organising agent work, such as routing tasks or having one agent check another's output. Its makers say simple patterns like these are more reliable than complex designs.

Agents can be scaled up to long-running jobs that pause and resume, and deployed to the cloud.

Who it's for

Python developers building AI agents.

Can I use it without coding?

Developers only. It's a programming framework and needs an API key for an AI model. New to this? Start here.

Can I run it?

Cost
Free, but needs an AI accountThe software is free, but it uses an online AI service (like OpenAI or Anthropic), which usually charges for use.
Computer
An ordinary computer is fine
Privacy
Sends what you give it to an online service
API key
Needed. An API key is a password-like code from an online AI service. What's that?
