Twig

Twig is an MCP (Model Context Protocol) server designed to audit, score, and optimize the tool descriptions exposed by other MCP servers and agent cards. Its core capabilities include analyzing how likely an AI agent is to choose a given tool or service based on its description, monitoring competitive position and search intent trends, and generating higher-performing description variants. Twig integrates with MCP-compatible systems, OpenAPI specs, local JSON schemas, and the x402 discovery catalog, making it useful for tool builders, agent developers, and marketplaces wanting to improve agent 'selectability' and revenue via optimized positioning.
