A Model Context Protocol server that provides semantic search and intelligent access to a comprehensive list of free services and tools for developers.

Enables AI assistants to search, read, and cite Title 38 of the Code of Federal Regulations from a locally built SQLite full-text index, using read-only tools for ranked regulation search, full section retrieval, hierarchy browsing, part listing, and index freshness/health checks. All queries run offline against the local index, returning ranked hits with citations, snippets, cross-references, and staleness notices.

A local-first, no-API-key MCP server that enables LLMs to search the web, fetch pages, and read documents using multiple engines and smart fallbacks.

Enables keyless search and retrieval of millions of openly-licensed Creative Commons images and audio, with ready-to-paste attribution and license-awareness built into every result.

An MCP server that provides real-time weather data, hourly forecasts, and daily summaries using the free Open-Meteo API with no API key required. It enables users to search for weather conditions by specific coordinates or city names across multiple measurement units.

Enables AI agents to search the web, read any page as clean markdown, and query Wikipedia, Hacker News, and GitHub without API keys or per-call credits. It exposes these sources as unified MCP tools and can also be self-hosted over HTTP or used as a library.

This MCP server enables free web search and page content extraction using real browsers, with support for multiple search engines and stealth browser backends. It provides tools for searching, fetching pages, and setting up the Camoufox stealth browser.

Enables any MCP client to run keyless multi-engine web searches with RRF fusion, fetch pages and documents as Markdown, and full-text search a local SQLite index. It keeps queries and cached content on the user's machine, degrading gracefully across engine tiers when providers are blocked or rate-limited.

Enables AI agents to discover and query 48 live data APIs spanning real estate, products, travel, jobs, sports and finance, with schema-aware request validation and execution from natural language tasks. Sources are searched, endpoints inspected and identifiers resolved before making a single live RapidAPI call.

Provides tools to retrieve information about current and upcoming free games on the Epic Games Store. It allows users to access game details including titles, descriptions, and claim URLs through Model Context Protocol clients.

Provides an OpenAI-compatible gateway to the MiMo (Xiaomi) model series, with native MCP server tools for web search and visual analysis.
