Find agent harnesses / MCP servers
search_harnessesRead-onlyIdempotent
Find an existing MCP server, SDK or agent framework that connects an AI agent to a service or does a task, from Loadbay's curated catalog. Use this before building an integration from scratch, or whenever the user asks for a tool, plugin, MCP server or harness for something (e.g. "MCP server for Postgres", "browser automation for agents", "crypto trading bot framework", "Slack integration"). Returns matches ranked by relevance then GitHub stars, each with repo URL, license, language, integrations and traits. All filters are optional; with none it returns the most-starred harnesses.
