Developer's MCP server audit tools find bugs in themselves first

By PulseAugur Editorial · [1 sources] ·

A developer created three independent command-line tools to audit Model Context Protocol (MCP) servers, focusing on documentation, safe failure modes, and realistic output validation. During testing, each tool unexpectedly identified bugs within its own logic before finding issues in the target servers. One tool, mcp-fuzz, revealed that all 27 tools in the popular antvis/mcp-server-chart project crashed when given malformed input, a bug that was later found to be fixed in an unreleased commit. AI

IMPACT These tools offer a novel, deterministic approach to verifying MCP server correctness, potentially improving reliability in AI agent development.

    I built three tools to audit MCP servers. Each one found a bug in itself first.

    <p>Over the last couple weeks I built three small, independent CLIs that each check a different way an MCP (Model Context Protocol) server can be broken — not by reading marketing copy, but by pointing them at real, popular servers and reading what came back.</p> <p>The three too…
