Flexible Key-Value Extracting MCP Server

This MCP server extracts key-value pairs from arbitrary, noisy, or unstructured text using LLMs (GPT-4.1-mini) and pydantic-ai. It keeps type safety and supports multiple output formats (JSON, YAML, TOML). The server is robust to any input and always attempts to structure data as much as possible.
