Pulsar
Semantic router that enables intelligent tool discovery and execution across multiple MCP servers using embeddings and vector search to eliminate context bloat while providing natural language tool access and progressive exploration.
About
Pulsar is a semantic router for MCP ecosystems that enables AI agents to discover and execute tools across multiple MCP servers without context bloat. Built with FastMCP, it uses embeddings and vector search to provide natural language tool discovery, progressive exploration with minimal token usage, and background task execution with inter-process communication. The implementation features content management for large results, server lifecycle management, access controls, and a unified semantic router interface that consolidates all operations across distributed services.
