Publishes a spending-summary tool alongside an interactive HTML view, letting people click a category in the answer to fetch the individual expense records behind that total. Keeps calculations and their supporting evidence together in a single inspectable flow.

This MCP server enables AI agents to perform exploratory UI testing of live web apps by providing a structured view of page elements, deterministic correctness oracles, enforced read-only or opt-in write policies, persistent cross-run memory, and gap-checked coverage reports.

Enables AI assistants to bulk-check hundreds of brainstormed domain names in a single call, reporting which are available, taken, or reserved along with buy links and prices from multiple registrars. It runs locally via DNS, RDAP, and WHOIS lookups, with optional registrar API keys for confirming availability and premium pricing.

Enables users to draw GIS geometry on an interactive map and get clean, validated GeoJSON to hand off to other GIS MCP servers such as FEMA flood screening and USGS hydrography.

Enables generation of chemical structures, reactions, spectra, titration curves, 3D models, and more from natural language or SMILES, using RDKit for offline rendering and supporting formats like PNG, SVG, CDXML, and Anki decks.

Enables currency conversion and exchange rate lookups using real ECB reference rates, free and without an API key. Supports natural language queries like 'convert 100 USD to EUR' or 'what's the exchange rate between GBP and JPY?'.

Returns an Ed25519-signed offer (VRP) and the host’s direct booking URL. The guest books and pays the host. Do not use to compare hosts or prices.

Gives AI assistants live access to US prescription drug prices by pharmacy with observation dates, the free discount card, and vetted US equivalents of foreign-brand medicines, all through the Model Context Protocol.

BlackForge measures the order books of the major crypto exchanges in real time: depth, liquidity added and pulled, order ladders and what actually traded. 150+ metrics for 14,000+ pairs, in a dashboard or over REST, MCP and a CLI.

Publish Markdown or HTML to a shareable link from your AI assistant, then list, inspect, update or delete your pages. Six tools cover publishing, page management and account usage. Connect through hosted Streamable HTTP with OAuth, or use an API key for headless clients.

Enables live preview of Storybook components inside the IDE as the AI edits them, using MCP Apps integration.

A MCP Server that lets user ask AI models to discover the collection of the Metropolitan Museum of Art. Adds the discovered art works as Resources on the server.

An MCP server that lets LLM agents autonomously play retro games by driving a real OpalEmu emulator in a Playwright-controlled browser, exposing tools for loading ROMs, controlling buttons, and capturing screenshots.

Provides real-time weather temperature queries for any city with an interactive UI form, using Open-Meteo API (no API key needed).

An MCP server that lets Claude or ChatGPT read, create, and edit mind maps stored in a GitHub repository, with support for local and HTTP transport.

An MCP server that integrates with SerpApi to retrieve search results from multiple search engines including Google, Bing, Yahoo, and others, enabling fast access to both live and archived search data.

Enables UPS shipping operations on your own UPS account: negotiated rate shopping, live tracking with an interactive MCP Apps card, and landed-cost estimates for international shipments.
