What it does

Built for how agents actually read code.

So your agent spends tokens on the right code, not on grepping.

01

Semantic search

Find code by what it does, not by keyword.

02

Local by default

Everything stays in ~/.clean/. No keys, no telemetry.

03

MCP-native

Drops into any MCP client over stdio. One line of config.

04

Index anything

Point it at a local folder or a public GitHub repo.

05

Tree-sitter parsing

Real AST parsing for Python, JS, and TS — not regex.

06

Call-graph aware

Every result carries its callers and callees.

Choose how you run it

Self-host it free, or let us run it.

Same search either way — your laptop or our cloud.
