rnv-color-mcp, a hosted color-workflow MCP server (Python, Streamable HTTP). Tools: mix (including Kubelka-Munk paint physics), convert between formats, generate harmonies, transform text case, and save/list/get named palettes. It resolves hex / CSS / custom brand color names and refuses unknown colors rather than guessing.

Free platform to test MCP clients without installing anything. Create mock tools with dynamic templates, configurable delays, conditions (if/then), and response sequences. Supports JSON-RPC 2.0 over Streamable HTTP. Built-in text_echo and json_echo tools. Rate-limited tiers: anonymous (5 calls/min, 1 mock tool), registered (10 calls/min, 4 mock tools), premium (60 calls/min, unlimited). Zero setup — no install, no registration required.

All analysis is deterministic and local to the request.
