evolveguard

04

RudrenduPaul/evolveguard

MCP server Claude CodeCodexCursor

Regression-testing CI gate for self-edited Claude Agent Skills (SKILL.md, MEMORY.md): golden-transcript record/replay against a skill's own declared and inferred capability surface, zero hosted infrastructure. Runs locally from the evolveguard-cli Python package.

hotato

05

attenlabs/hotato

MCP server Claude CodeCodexCursor

Find what broke in your agent calls. Pin it and CI stays red until you fix it. Local call forensics and regression guards for AI agents: turn timing, and whether the agent did what it said. Nothing leaves your machine. Runs locally from the hotato Python package.

agent-eval

07

RudrenduPaul/agent-eval

MCP server Claude CodeCodexCursor

Statistical regression testing for LLM agents. Get a p-value on whether behavior actually shifted between versions, not just whether one run looked different. Apache 2.0, self-hostable, no SaaS dependency -- a Promptfoo alternative for the statistical testing gap threshold-based eval tools don't cover. Runs locally…

tokentrust-cli

08

RudrenduPaul/TokenTrust-CLI

MCP server Claude CodeCodexCursor +2

Vendor-neutral CLI and MCP server that verifies the token and cost savings AI-coding-agent context-reduction proxies (rtk, headroom) actually deliver, measured against a real 23-task labeled corpus with a local tokenizer instead of the proxy's own claimed. Runs locally from the tokentrust-cli npm package.

agent-regress

09

Gaurav7974/agent-regress

MCP server Claude CodeCodexCursor +2

agent-regress is a local MCP (Model Context Protocol) server that provides tools for AI coding agents to execute, evaluate, and diff regression tests for LLM agents. It integrates directly into your existing AI coding environment via the Model Context Pro. Runs locally from the agent-regress npm package.

staysfixed

11

asadev/staysfixed
