AI agent rigorously tested before fixing open-source bugs

By PulseAugur Editorial · [1 sources] ·

The author details a rigorous process for developing an AI agent capable of automatically fixing bugs in open-source projects, specifically focusing on MCP servers. The agent was designed to identify and correct a specific bug related to null default parameters in Python MCP servers. Before deployment, the agent underwent two gates: first, by replaying its fixes against previously merged code to ensure accuracy and avoid unnecessary changes, and second, by testing on unseen repositories to assess its ability to find new bugs without introducing errors or compromising reputation. AI

    Before I let an agent open PRs on strangers' repos, I made it earn it

    <p>Over the last six weeks I've had 44 bug fixes merged into other people's open-source projects, most of them MCP servers. Many came from the same loop: <a href="https://github.com/vishalhabib99/mcp-doctor" rel="noopener noreferrer">mcp-doctor</a>, my static linter for MCP serve…
