"Finding MCP servers with high ratings and no API key required" matching MCP servers:

A Multi-Agent Conversation Protocol server that provides an interface to Google's Cloud IoT API, allowing agents to interact with and manage IoT devices and registries through natural language.

Enables local MCP access to read TRMNL devices and manage playlist items, visibility, ordering, and weekly display windows.

Enables to retrieve device information, images, media, location, thumbnails, and events from the Safie API through MCP.

Provides read-only access to Shelly Cloud energy data, including live power, lifetime energy, and historical consumption with cost, enabling AI agents to monitor electricity usage without device control.

An MCP server that enables communication with Twilio's Microvisor API, allowing interaction with IoT devices managed by Twilio's Microvisor through natural language.

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.

Enables AI agents to interact with Homey home automation systems for managing flows, devices, and zones. Perfect for bulk automation tasks like batch renaming flows, organizing them into folders, and managing devices across zones through natural language.

Allows a locally running MCP host to send a single verified close-door command to a Tuya roller shutter over LAN, with explicit confirmation and DPS mapping required for safety.

Controls GREE/EWPE-compatible WiFi air conditioners directly over your LAN using native UDP protocol. No Homebridge or cloud required.

Enables natural language control of Homey Pro smart home systems, including devices, flows, zones, energy monitoring, weather, alarms, and system management, with 43 tools and troubleshooting prompts.

Enables control and management of smart home devices across multiple rooms through specialized MCP servers. Supports lights, thermostats, fans, and ovens with room-specific rules and automatic persistence.

Enables registration, monitoring, and control of IoT devices via AI agents, with local storage and no cloud API key required.

Control a Vizio SmartCast TV over your local network via the SmartCast local API, with no cloud required.

Enables LLM sessions to query the SensorMesh open IoT sensor data commons, including device inventory, filtered reading windows, and per-sensor statistics, with no API keys required.

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

Enables LLMs to read, write, browse, search, and subscribe to live data on OPC-UA industrial automation servers, with caching, discovery index, and support for stdio or HTTP transports.

MCP servers for querying Brick and 223P ontologies, enabling abbreviation expansion, term/property lookup, and definition retrieval.

Enables AI agents to monitor and control Nokia G-2425G-A GPON home routers (e.g., Airtel) via natural language, including listing connected devices, and blocking or unblocking internet access for specific devices.

Connects embodied devices (like StackChan, Raspberry Pi, ESP32) to AI via MCP protocol, enabling motion control with zero API cost, no PC required, and fully self-hosted.

Enables MCP-compatible assistants to retrieve live data from an iopool pool account, including water temperature, pH, ORP, running mode, and filtration recommendations, and to list the account's pools. Access is authenticated with the user's own iopool API key, via OAuth or a direct bearer header.
