An MCP server for automating the PlayCanvas Editor with an LLM. The MCP client is built into the Editor — no browser extension needed. Install the server into your MCP client of choice (Claude Code, Codex, Claude Desktop, Cursor, ...) and connect the Editor to it.
Installation
Requires Node.js 22.18+. The server is published to npm as `@playcanvas/editor-mcp-server` — a self-contained, zero-dependency bundle — so every client below runs it with npx. Nothing to clone or build.

Questions
What is the PlayCanvas Editor AI Automation MCP server?
MCP Server for AI automation of the PlayCanvas Editor
What tools does PlayCanvas Editor AI Automation expose?
125 in total: 73 read-only, 42 that write, and 10 that can delete or overwrite (clear_cubemap_prefilter, clear_selection, delete_assets, delete_branch, delete_build). Every one is listed on this page with its risk.
Is PlayCanvas Editor AI Automation safe to connect to an agent?
The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B. Separately from the audit: 10 of its tools can destroy data, so scope the token you give it to what you actually need.
What credentials does PlayCanvas Editor AI Automation need?
No credential environment variables were found in its source, so it appears to need none.
How does PlayCanvas Editor AI Automation run?
It speaks stdio, so it runs as a local process your client starts. It is published on npm as @playcanvas/editor-mcp-server at 0.7.1.
How current is this page?
The grade is for one exact copy of the source (21f985f97a3e), read on 2026-10-07. The repository is watched and re-audited when it changes.
