"MCP servers that work without API keys" 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 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.

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.

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 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.

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.

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

An MCP server that lets an MCP client control IKEA TRÅDFRI smart plugs paired to a DIRIGERA hub via its local REST API.

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.

ac-infinity-mcp is an MCP server that connects Claude (and other AI assistants) directly to your AC Infinity controllers — so you can read live sensor data, run analytics, and adjust fan speeds or port states using natural language, without opening the AC Infinity app.

MCP server for Hubitat Elevation hubs that controls devices via the Maker API, with optional gated access to undocumented admin routes, supporting device listing, command sending, virtual device and hub variable automation for Rule Machine, and hub management features.

Enables control of Philips Hue lights via Bluetooth LE directly from Claude, without requiring a Hue Bridge or internet connection.

Enables control of Sprut.hub smart home devices through dynamic API discovery and schema validation.

MCP server that enables AI agents to control Twinkly lights through natural language, supporting operations like on/off, color, brightness, and effects.

A hub that serves multiple MCP servers from a single container over HTTPS, with OAuth 2.1 authentication and path-based routing.

A lean Model Context Protocol (MCP) server that gives AI assistants like Claude structured access to a SolarEdge PV installation via the official SolarEdge Monitoring API.

Enables AI assistants to control Govee smart devices, including lights, via natural language. Supports turning on/off, changing colors, adjusting brightness, and activating scenes through the Govee API or local network.
