Castov: open-source zero-telemetry DevSecOps MCP server for local agents
benidira · reddit · 2026-10-20
A developer released Castov, an open-source (MIT), local-first DevSecOps utility and MCP server that plugs into Claude Desktop, Cursor, or custom local agent setups.
Core features via MCP: local secret/credential scanning before pushes (API keys, tokens, env leaks), instant port-conflict diagnosis and cleanup (e.g., EADDRINUSE: 3000), and a structured knowledge base of 1,000+ framework/tool error resolutions (Next.js, Docker, Supabase, Ollama).
Privacy: fully offline-first with zero telemetry—no logs, credentials, or code snippets leave the machine. JSON-RPC 2.0 compliant; try it with npx -y castov@latest mcp.
