opik-mcp vs fastmcp
opik-mcp: opik-mcp is a Model Context Protocol server that integrates Opik, an LLM observability platform, with AI coding assistants like Claude Code, Cursor, VS Code Copilot, and MCP Inspector. It enables reading traces, scoring, saving prompt versions, and asking Ollie investigative questions directly from chat. Requires Python 3.13+ and uses uvx for execution.; 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.
