Context7: Context7 is an MCP server that injects up-to-date, version-specific library documentation directly into LLM prompts. Add "use context7" to any coding prompt and it fetches current docs for the library you're working with, eliminating hallucinated APIs and outdated code examples. Works with Claude Desktop, Cursor, Windsurf, and any MCP-compatible editor.; portfolio-mcp: portfolio-mcp is a Model Context Protocol (MCP) server that allows users to interact with their XP Investimentos portfolio via Claude Desktop. It processes official PDF/CSV exports from XP, stores the normalized data in a local SQLite database, and answers portfolio-related questions without sending sensitive information externally. It provides analytical tools for asset allocation, returns calculation, and market data screening.
