onetool-mcp: OneTool MCP is a single MCP server that bundles 100+ tools — Brave search, Google, Context7, AWS, Playwright, Chrome DevTools, Excel, database operations, and more. Instead of registering each tool individually and burning context on their definitions, agents write short Python code to call any tool on demand. Anthropic engineering research backs this approach: code execution reduces token usage by over 98%, cutting costs dramatically when agents need many external tools.; welink: WeLink is a WeChat chat data analysis platform that visualizes your chat history with detailed statistics, sentiment analysis, and time-based insights. It supports friend analysis, group chat analysis, global search, and privacy shielding, all running locally on your machine. The platform also provides an MCP server for querying data via natural language using Claude Code.
