Exposes an MCP server\nfor integration with coding agents.\n\n## TLDR\n\n(not written by AI)\n\n- Semantic, lexical, and RRF indexing and search for codebases.\n  - Results in sub-second response times for most search queries on\n    indexed codebases.\n  - Index and blob data stored in `.ultrasync` directory, be sure to\n    gitignore.\n- Structured memory and recall tools, _without_:\n  - Additional LLM calls\n  - Convoluted, vibe slopped together abstractions or interfaces\n  - Pollution of repository with arbitrary \"human readable\" Markdown\n    slop files\n- Network-speed pattern recognition based heuristics for classification\n  of contexts and codebase insights (like inferring TODOs, comments,\n  code smells, etc.).\n  - Intentionally fuzzy heuristics to improve p50 performance\n    dramatically and reduce token spend for some of the most common\n    codebase understanding tasks.\n- Exposes an MCP server for integration with coding agents, virtually\n  no configuration required.
