AI coding assistant

Connect a supported coding agent to the Unreal Editor so it can set up Convai characters and read Convai's skill library for you.

The Convai Unreal Engine plugin registers the Convai Toolset with the engine's own Model Context Protocol (MCP) plugin, adding seven Convai-specific editor actions and a library of Convai skill documents that a connected coding agent can read and call. Use this section once the Convai plugin is installed and you want a coding agent such as Claude Code or Cursor to set up Convai characters, players, and actions inside your Unreal project instead of you wiring them by hand.

Before you begin: AI coding support requires Unreal Engine 5.8 or later and only exists in Editor builds — the ConvaiToolset module throws a build error on any non-Editor target. On UE 5.0–5.7 the plugin still compiles, but the AI coding tooling is not present. See AI coding assistant quick start for the full setup walkthrough.

What the Convai Toolset adds

The engine's ModelContextProtocol plugin already gives a connected coding agent generic MCP tools for editing a project. The Convai Toolset adds seven AI-callable editor actions on top of that — SetupConvaiCharacter, SetupConvaiPlayer, SetupConvaiPawnMovement, AddNavMeshVolumeForCurrentLevel, SetBlueprintPropertyAndPropagate, AddConvaiAction, and CreateConvaiActionHandler — registered with the engine's ToolsetRegistry plugin. See Convai Toolset reference for what each action does and its parameters.

The plugin also ships 17 skill documents under Content/Skills/ in the plugin's own content, which an agent lists and reads through the toolset's AgentSkillToolset (ListSkills and GetSkills). These documents describe Convai workflows such as project setup, MetaHuman setup, actions, and dynamic context, so an agent can look up how a feature works before calling a toolset action. See Convai AgentSkills for the full list.

Supported coding agents

Setup supports five agents: Claude Code, Cursor, VS Code, Gemini, and Codex. Each agent gets its own project-root context file — for example CLAUDE.md for Claude Code — with a sentinel-delimited Convai primer block when you choose to add one. See Supported coding agents for the exact file and per-agent behavior.

Connect a coding agent to your project

Open the Convai editor window, click the Settings icon, and select Set Up AI Coding (MCP). Choose an agent, set the setup options, and restart the editor when prompted. See AI coding assistant quick start for the full walkthrough and verification steps.

Not the same as a character's own MCP connections

This section covers a coding agent calling Convai's editor tools while you build a project in the Unreal Editor. It is a different subject from MCP Servers, which covers a Convai character calling an external MCP server during a live conversation with a player.
