Cali is an AI calorie tracker and weight-loss coach that works inside ChatGPT and Claude. Just say what you ate — or snap a photo — and Cali logs it, estimates the calories, tracks your daily total, weight trend and streak, and coaches you. No separate app to download: it runs as an MCP connector in Claude (or an app in ChatGPT), works on web, phone and desktop, learns your regulars so logging gets faster, and is judgement-free. Free 3-day trial.

cityparity gives AI agents real cost-of-living and quality-of-life comparison tools. Point it at two cities and it returns take-home pay, a full cost breakdown (housing, healthcare, childcare, food, transit, travel home, property tax), and the equivalent salary you'd need in the target city to come out even. It also surfaces the non-cash deltas people actually move for: vacation days, parental leave, universal healthcare. Beyond two-city compares, it ranks cities by a composite quality score and looks up inbound-worker tax regimes (Italy impatriati, Portugal IFICI, and a few others). Over 165 cities across 69 countries. Free, no API key, hosted Streamable HTTP.

A second opinion in Claude Code or any MCP host, from GPT, Gemini, Grok, and 400+ OpenRouter models. Seven domain experts review plans, find bugs, and weigh tradeoffs - advisory by default, or implementing when you ask.

A Serper MCP Server

Zhipu Web Search MCP Server is a search engine specifically designed for large models. It integrates four search engines, allowing users to flexibly compare and switch between them. Building upon the web crawling and ranking capabilities of traditional search engines, it enhances intent recognition capabilities, returning results more suitable for large model processing (such as webpage titles, URLs, summaries, site names, site icons, etc.). This helps AI applications achieve "dynamic knowledge acquisition" and "precise scenario adaptation" capabilities.
