Srclight
Deep code indexing for AI agents. SQLite FTS5 + tree-sitter + embeddings + MCP.
Srclight builds a rich, searchable index of your codebase that AI coding agents can query instantly — replacing dozens of grep/glob calls with precise, structured lookups. It is the most comprehensive code intelligence MCP server available: 42 tools covering symbol search, relationship graphs, community detection, impact analysis, git change intelligence, semantic search, build system awareness, and document extraction — capabilities no other single MCP server combines. Fully local and private: your code never leaves your machine.
Why?
AI coding agents (Claude Code, Cursor, etc.) spend 40-60% of their tokens on orientation — searching for files, reading code to understand structure, hunting for callers and callees. Srclight eliminates this waste.
| Without Srclight | With Srclight |
|---|---|
| 8-12 grep rounds to find callers | get_callers("lookup") — one call |
| Read 5 files to understand module | codebase_map() — instant overview |
| "Find code that does X" → 20 greps | semantic_search("dictionary lookup") — one call |
| Edit a function, break 47 callers | detect_changes() — shows blast radius before you commit |
| 15-25 tool calls per bug fix | 5-8 tool calls per bug fix |
