BLAH (Barely Logical Agent Host)

BLAH (Barely Logical Agent Host) is an open-source ecosystem for managing and executing AI agent tools using the Model Context Protocol. Developed by Thomas Davis with contributions from Lisa Watts and Wombat, it provides a CLI tool for creating, testing, and sharing MCP servers that can be consumed by any MCP-compatible client like Claude Desktop, Cursor, or Windsurf. The implementation includes a visual flow editor for designing agent workflows, a simulation environment for testing tool interactions, and support for both local and remote tool registries. BLAH focuses on decentralized tool discovery and execution, making it particularly valuable for developers building composable AI agent systems.
