# FiveM MCP

This MCP server lets an AI agent run and test FiveM through FXServer and a live client, with console access, logs, and game control.

## What it does

FiveM MCP connects an AI agent to FXServer over UDP RCON and to a Legacy FiveM client through devcon. The agent can inspect server details, send console commands, read client or server output, wait for a regex match, and launch the client at a chosen address.

The server requires Node 22+, an FXServer you administer, and `FIVEM_RCON_PASSWORD` matching `rcon_password`. Set `FIVEM_SERVER_LOG` to enable server-log reading; the `mcpb` bridge uses `FIVEM_MCPB_TOKEN`. Keyboard, mouse, and screenshot tools run on Windows only. Client-console tools depend on the Legacy client because Enhanced removed the client devcon ports.

## Requirements
- Needs: Node.js (commands run via npx)
- Environment variables: `FIVEM_HOST`, `FIVEM_CLIENT_DEVCON_PORT`, `FIVEM_RCON_ADDRESS`, `FIVEM_RCON_PASSWORD`, `FIVEM_SERVER_LOG`, `FIVEM_MCPB_TOKEN`, `FIVEM_EXECUTABLE`, `FIVEM_CONSOLE_CAPACITY`, `FIVEM_QUIET_MS`, `FIVEM_COMMAND_TIMEOUT_MS` — keys and tokens: ask the human for the values, never commit them or put them in shared files.

## Install

## When to use it
- test a resource in a live FiveM client
- send FXServer commands over RCON
- inspect the FiveM client console
- wait for a matching log line
- launch and quit FiveM from an agent

## Example prompts
- Check the server and client connections with `status`, then report which paths are ready.
- Launch FiveM at `host:port`, run a client check, and wait for a matching line with `wait_for_console`.
- Send a server console command through `server_command` and return its output.
