MCP Server for persistent code indexing. Gives AI assistants (Claude, Gemini, Copilot, Cursor) instant access to your codebase. 50x less context than grep.

Graded coding exercises inside a chat. The assistant writes the lesson and the hidden tests, the widget runs them in the browser, and a failed attempt goes back into the conversation so the tutor explains your specific mistake. Python, JavaScript, TypeScr

Classify SQL as safe, risky, destructive, or unknown before it runs — the pure, dependency-light, publicly-audited classifier behind Undrop's AI-agent database safety net.

Progressive deep research engine with knowledge graph, trust scoring, and self-regulation. MCP server for Claude Code, OpenClaw, or any MCP client.

Model Context Protocol server for AskSQL: exposes list-connections / schema / query / run as MCP tools so AI agents can safely query registered databases (read-only, guarded).
