grainulator vs fastmcp
grainulator: Grainulator is a research tool that runs multi-pass investigations to answer questions with typed claims, tension detection, and confidence scoring. It compiles evidence from multiple angles and provides a graded answer in under 60 seconds.; fastmcp: FastMCP is a standard framework for building Model Context Protocol (MCP) applications, which connect LLMs to tools and data. It simplifies the process by automatically generating schemas, validation, and documentation for tools, and managing transport negotiation and authentication for server connections. FastMCP offers a comprehensive solution for developing, deploying, and scaling MCP-powered systems.
