Rivemcp

npm

Polymation — the multi-format AI animation MCP. Author Rive (.riv/.rev) and Spline (.splinecode/.spline) scenes from scratch and convert Rive↔Spline, validated on the real runtime. The most complete Rive MCP, now multi-format.

Works with: Claude Code, Cursor, Claude Desktop, Codex CLI, Gemini CLI, Cline, Windsurf, VS Code (installable)
installable: each client documents how to load an MCP server of this type — that is the client's promise, not a claim verified against this capability

You are reading this because you came looking. tashan Pro gives tashan doctor the history behind it, so a run over your own config says which of YOURS moved.

You searched for one. Check the rest of your stack:

npx tashan-cli doctor

Reads the config already on your machine and names what is dead, deprecated or running code at install time. No account, nothing uploaded.
