sylvan

Code intelligence platform for AI agents. Search, analyze, and navigate codebases through MCP tools — returning exactly the code your agent needs at a fraction of the token cost.

AI agents burn tokens reading entire files when they need one function. They grep across directories to trace a dependency. They piece together call chains one file at a time. Every wasted read costs money and context window space.

Sylvan indexes your codebase into a structured database of symbols, sections, and import relationships, then exposes it through 52 MCP tools. Your agent asks for what it needs and gets exactly that — function signatures, blast radius, dependency graphs, semantic search results. Typical token savings exceed 80%.

Search — find code by name, signature, or keywords with syntax-highlighted source

Session — live token efficiency tracking per session and all-time

Quality Report — code smells, security findings, test/doc coverage

Blast Radius — visualize impact before changing a symbol

Libraries — indexed third-party packages with symbol counts
