What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

This one needs environment variables set before it will start: FIVEM_HOST (Machine running the FiveM client (DevCon host). Default 127.0.0.1), FIVEM_CLIENT_DEVCON_PORT (Override the client devcon port (default: try 29200 then 29300)), FIVEM_RCON_ADDRESS (FXServer game host:port for RCON/getinfo. Default <FIVEM_HOST>:30120), FIVEM_RCON_PASSWORD (Matches rcon_password in server.cfg; required for server_command and the bridge), FIVEM_SERVER_LOG (Path to FXServer's redirected stdout (server.log); enables server-side read_console/wait_for_console (optional fallback transport for pre-0.5 bridges)), FIVEM_MCPB_TOKEN (Matches mcpb_token on the server when the bridge resource is configured with one), FIVEM_EXECUTABLE (Path to FiveM.exe for the launch tool. Default %LOCALAPPDATA%\FiveM\FiveM.exe), FIVEM_CONSOLE_CAPACITY (Client console lines kept in the ring buffer. Default 5000), FIVEM_QUIET_MS (Consider client command output complete after this quiet period. Default 400), FIVEM_COMMAND_TIMEOUT_MS (Default max wait for client_command output. Default 5000), FIVEM_MCP_DEBUG (Set to 1 to trace devcon frames and RCON round-trips on stderr). The author declared them in the registry entry; get the values from the project itself.
