VRChat MCP
Let your coding agent query and act on VRChat friends, worlds, groups, events, notifications, and VRCX history through MCP instead of manual API spelunking.

What problem does it solve?
VRChat builders waste time hand-rolling API calls and cookie auth when they want an agent to answer social, world, or event questions in code.
Who is it for?
VRChat community toolmakers and solo devs building bots, dashboards, or agent workflows that need live friends, worlds, groups, and event data.
Skip if: Builders with no VRChat account or API need, or anyone who wants generic web automation without VRChat-specific auth and rate limits.
What do I get? / Deliverables
After registration, your agent can use typed MCP tools to read and work with VRChat and VRCX data while you build companion tools or automations.
- VRChat MCP server wired into your agent client
- Tool-backed access to friends, worlds, groups, events, and notifications
- Optional VRCX history queries for richer agent context

Journey fit
VRChat automation lands in Build when you integrate a live social API into tools, bots, or companion apps. Integrations is the right shelf for a domain-specific MCP bridge to VRChat and VRCX, not generic agent memory or infra monitoring.
How it compares
VRChat API MCP integration, not a game engine skill or generic browser MCP.
Common Questions / FAQ
Who is VRChat MCP for?
Developers and creators in the VRChat ecosystem who want Claude Code, Cursor, or similar agents to query social and world data through MCP.
When should I use VRChat MCP?
Use it during Build when you are coding integrations that need friends, worlds, groups, events, notifications, or VRCX history from inside the agent.
How do I add VRChat MCP to my agent?
Install @basicbit/vrchat-mcp, configure VRChat authentication (cookie store and optional VRCHAT_MCP_CONFIG_FILE), add the stdio MCP server in your client, and set VRCHAT_MCP_USER_AGENT appropriately.
