Provides tools for interacting with Construct 3 projects, including documentation search, project querying (objects, eventsheets, layouts), project mutation (creating/updating/deleting objects, events, layouts), animation management, project analysis (dependency graph, performance audit, validation), and scripting support (reading/writing JavaScript files).
Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@ultimate-construct3-mcp search documentation for touch input"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.

Scored across 6 tools
Each tool targets a distinct facet of the docs surface (search, browse topics, browse categories, fetch topic, ACE reference, examples). The only mild overlap is between search_docs and get_examples, since both are query-style lookups, but the example-specific description makes the boundary clear enough.
All names follow a clean verb_noun snake_case pattern (search_*, list_*, get_*), with verbs matching the operation type. No mixed conventions.
Six tools is a well-scoped set for a documentation lookup server — one query tool, one content fetcher, two browsing tools, plus ACE and example lookups. Each earns its place without redundancy.
The surface covers the full docs workflow: browse categories/topics, search, fetch full content, and specialized ACE/example lookups. Minor gaps exist (e.g. no versioned docs or plugin-name discovery for ACE), but agents can work around them via search.
