"Building voice agents and controlling SIP phones" matching MCP servers:

Local voice and AI platform for macOS offering speech recognition, speech synthesis, MLX-based inference, OpenAI-compatible APIs, and MCP tools for use as an assistant or integration gateway.

Sensact is a Supabase-hosted remote MCP server that lets LLM clients discover and invoke device capabilities on user-owned devices, using OAuth 2.1 for authorization and Postgres+Realtime as the control plane.

A Model Context Protocol (MCP) server that allows AI assistants like Claude to control real smart bulbs via UDP network communication, featuring voice commands, AI reasoning, and direct hardware control.

Exposes a Home Assistant instance as an MCP tool set, running as a stateful agent on Cloudflare Workers, enabling clients to read entity states, call services, run scripts and automations, and send commands to phones.

Enables controlling an Anova Precision Oven through MCP, including reading temperatures, starting and managing cooks, and capturing camera frames.

Enables controlling PiShock devices (shock, vibrate, beep) via the MCP protocol with API key authentication.

MCP server for controlling a Nabaztag rabbit's ears, LEDs, and voice pipeline, enabling AI tool-use via Claude Desktop/Code.

A LAN-first, cloud-fallback MCP server for controlling Govee smart devices by name. It enables AI agents or MCP clients to manage lights, plugs, and appliances with commands like power, brightness, color, and scenes.

Enables controlling Roborock vacuums through MCP, exposing status, rooms, cleaning history, consumables, and robot controls.

Enables AI agents to manage multiple 3D printers via MCP, including monitoring temperatures and progress, uploading and slicing models, controlling prints, and viewing cameras.

Exposes real-time soil sensor metrics as MCP Resources and irrigation valve controls as MCP Tools, enabling AI-driven agronomic decisions with built-in safety guardrails.

MCP server for controlling Somfy TaHoma devices locally via the box's API, without cloud dependency.

MCP server for controlling LED displays via MQTT. It enables AI agents to list devices and send text, images, colors, or clear commands with authentication and permission checks.

Enables AI agents to discover and call Xyte's device management API endpoints with typed validation, supporting fleet investigation, ticket management, and routine operations through natural language.

An unofficial read-only MCP server for Panasonic AiSEG2 home energy management controllers, enabling clients to read live power flow, per-circuit consumption, circuit names, daily totals, and historical energy/cost data from the device's local web interface.

A collection of personal Model Context Protocol servers for tools like calendar, contacts, flights, home maintenance, iMessage, lawn care, mail, NextDNS, Obsidian search, Google Sheets, UniFi, weather, and YNAB, packaged as a uv workspace with Claude Code and Codex plugin support.

MCP server that translates natural language commands into SCARA robot arm control instructions, featuring simulation mode, safety validation, and multiple transport modes (STDIO/HTTP/OAuth).

Enables natural language control of WeMo smart home devices for power, brightness, and device management through AI assistants. It features a high-reliability multi-phase discovery process to scan, monitor, and configure devices across a local network.

An MCP server that lets AI assistants answer home appliance questions with live, structured data and cite ApplianceIQ as the source.

Read-only MCP server for Home Assistant that computes statistical summaries, trends, and session detection from recorded sensor history, returning compact tables instead of raw data so small local models can answer questions about energy usage, climate, and appliance activity without token-heavy arithmetic.
