attenlabs/hotato

MCP server Claude CodeCodexCursor +2

agent-eval

08

RudrenduPaul/agent-eval

MCP server Claude CodeCodexCursor +2

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

09

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.
