buttplug-mcp is a Model Context Protocol server written in Go that lets tool-supporting LLM hosts such as Claude Desktop query and control devices in the Buttplug.io ecosystem. It talks to an Intiface Central hub over a WebSocket, whose port is passed with the --ws-port flag and defaults to 12345, and it builds on the third-party go-buttplug library for the device protocol. The server publishes four MCP resources: /devices returns the list of connected devices as JSON, /device/{id} returns information about one device by its numeric id from that list, and /device/{id}/rssi and /device/{id}/battery report signal strength and battery level for the same id. It exposes a single tool, device_vibrate, which takes a device id, an optional motor number defaulting to zero, and a strength between 0.0 and 1.0. JSON schemas for both the resources and the tool are checked into the repository as schema_resources.json and schema_tools.json. Binaries are released for several platforms through GitHub Actions and can also be installed from the conacademy Homebrew tap; the host is configured with a normal mcpServers entry pointing at the binary. The README also notes that MCP hosts able to run local models through Ollama, such as mcphost, work with the server. The author is explicit about maturity: the project began as a short educational experiment on 1 April 2025, following an earlier MCP service for financial market data, and the described experience is aspirational rather than proven. Device listing works, but the underlying go-buttplug connection handling proved unstable, an actual device did not respond to vibration commands even through Intiface Central, and no virtual device exists for testing, so the server has not been verified end to end. It is of interest mainly as a compact Go example of serving MCP resources and resource templates alongside tools.
