overte-mcp

What this wraps

An MCP server for Overte, the open-source social-VR platform — a C++ desktop client ("Interface") + domain-server + entity-server, descended from High Fidelity's codebase. Not the same thing as current "Vircadia" — see docs/WRAPPEE.md for the full disambiguation and official links (site, docs, community). Complements the fleet's other virtual-world servers: resonite-mcp, vrchat-mcp, godot-mcp, unity3d-mcp, gazebo-mcp.

Plus a companion React web dashboard.

What You Can Do

How it runs: Overte (domain-server + Interface) is a separate application you install yourself — never bundled. overte_domain_status works against just the domain-server (no GUI needed). overte_entity_spawn and overte_script_inject need a running Interface client with scripts/overte-mcp-bridge.js loaded, because Overte's entity-server has no plain HTTP "create entity" endpoint — only Interface's JavaScript API can do that. See docs/ONBOARDING.md for first-time setup.

Direction	Artifacts	Notes
Hands-in	Entity properties (position, scale, type), JS behavior scripts, GLB/FBX/OBJ model URLs	Via MCP tool calls or the dashboard's Entities/Scripting pages
Hands-out	Live domain-server telemetry, spawned in-world entities, animated/scripted entities	Every response labeled `source: "live"` or `source: "simulated"` — never a silent fake success

Tools — all three core tools verified live against Overte 2026.04.1 (2026-07-30):

Tool	Status
`overte_domain_status`	Verified live — real domain-server `/nodes.json` + `/settings.json` admin API on port `40100`
`overte_entity_spawn`	Verified live — in-world entity spawning via WebSocket bridge; `permanent=True` for cross-restart persistence
`overte_script_inject`	Verified live — in-world JS behavior injection via WebSocket bridge
`overte_sampling_assist`	Multi-step planning via `ctx.sample()` when host supports it

Dashboard pages:

Quick Install

Claude Desktop (`.mcpb`)

Build: just mcpb-pack → dist/overte-mcp.mcpb
Drag the .mcpb into Claude Desktop (needs Python 3.12+ and uv on PATH).

Stdio without MCPB: uv run overte-mcp. Full install paths: INSTALL.md.

Full stack (dashboard + bridge)

powershell

./start.ps1

Syncs deps, starts FastAPI backend (11110) and Vite dashboard (11111), opens the browser. Then start Overte domain-server.exe, open Interface, load scripts/overte-mcp-bridge.js for live spawn/inject — see docs/ONBOARDING.md.

Example Prompts

"What's the status of my Overte domain?"
"Spawn a permanent box entity at the origin"
"Attach the dance script to that entity"
