Developer Tools

A zero-config CLI proxy that logs every JSON-RPC message between your MCP client and server — with full payloads, timing, and colour-coded direction arrows. Drop it in front of any MCP server in seconds.

• Full JSON-RPC payload logging
• Per-message latency
• Works with Claude Desktop

A CLI debugging and testing toolkit for AI agent developers who build on MCP. Record every tool call, inspect traces, diff runs, replay deterministically, and assert in CI — no code changes required.

• Record every tool call as NDJSON traces
• Replay deterministically — no live server needed
• Assert in CI with YAML rules

A CLI-first data curation engine for ML engineers. Curates fine-tuning datasets by removing near-duplicates, scoring educational value, and detecting contradictions — reduce dataset size by 50–80% without sacrificing accuracy.

• Semantic deduplication with embedding similarity
• LLM-based quality scoring (1–10 scale)
• Contradiction detection — no API key needed

Collect human preference feedback on LLM outputs directly from your Python code. Submit pairs of model responses, pick the better one in a local browser UI, and export a DPO-ready JSONL dataset. Local-first, zero config.

• Local SQLite storage — no cloud
• Uncertainty-based filtering
• DPO-ready JSONL export

An intelligent tutoring extension for OpenClaw that remembers each student across sessions, tracks mastery concept-by-concept, detects prerequisite gaps, and adapts its teaching strategy using spaced repetition.

• Persistent student profiles
• Spaced repetition scheduling
• Adaptive teaching strategies
