MCPFlo: deterministic testing and debugging tool for MCP servers
MCPFlo is an offline-first, open-source Electron app for testing and debugging MCP servers. It replaces the common practice of relying on an LLM to judge server behavior with deterministic Chai.js-style assertions against real tool responses. It auto-generates nested schema forms via RJSF for easy input.

MCP server feeding live design tokens from real products to LLM agents
An MCP server that provides structured design tokens (colors, typography, spacing, etc.) extracted from live DOM of real products like Linear and Supabase. LLM code agents use these tokens via MCP to generate UI that matches a specific product's design system, avoiding generic outputs. Solves the problem of agents producing bland, average UI by giving them concrete design references.
whatbroke: CLI that captures context on test/dev server crashes for LLM debugging
whatbroke is a free open-source CLI that wraps any command (e.g., npm test) and, on a crash, captures a bundle of context: the error with parsed stack trace, the diff since the last passing run (recorded as a 'green' commit), and a ranked guess at the responsible file with reasons. This context is designed to be fed to an LLM (like Cursor) to enable accurate debugging, solving the problem of LLMs editing the wrong file when given only a stack trace.
Synapse: AI-powered bug detection before code is written
Synapse is a tool that uses LLMs to analyze software architecture and specifications to catch bugs before code is written. It addresses the problem of LLMs missing critical insights in security-critical and data-integrity projects, helping developers avoid bugs early in the development process.
Claude Code Flow Visualizer: interactive graph of agent harness
A tool that reads a Claude Code repository (GitHub, ZIP, or local folder) and generates an interactive graph showing agents, skills, hooks, slash commands, MCP servers, and their connections. It also detects issues like broken links, loops, unused skills, and reviewer problems, helping developers understand and debug complex Claude Code harnesses.
freddy: personal health data server connecting apps to LLMs
freddy is a mobile app that acts as a personal health data server, aggregating data from various health apps and devices. It uses an MCP server to expose this data to any LLM, enabling users to ask natural language questions that span multiple data sources, such as 'Which meetings raise my heart rate?'
