Find the exact slice
Search for behavior, not filenames. Contextro narrows the problem down to the right symbol or code chunk in milliseconds.
Local first / Single Rust binary
Contextro
Binario unico en Rust. Servidor MCP local para Claude, Cursor, Windsurf y otros clientes: busca codigo por significado, traza grafos de llamadas, inspecciona el impacto de cambios, consulta el historial git y conserva memoria entre sesiones sin enviar tu codigo a la nube.

Why it exists
See the change before you make it
Inspect callers, callees, impact, and commit history before renaming, deleting, or moving core code.
Keep the context window small
Return compact snippets, confidence signals, and sandboxed large outputs instead of dumping whole files into the model.
Core capabilities
Hybrid retrieval
Semantic search, BM25, graph signals, reranking, and AST-aware snippet compression in one local MCP toolchain.
Code graph awareness
Trace callers, callees, architecture hubs, and impact radius before you touch shared code or start a refactor.
Memory and knowledge
Store decisions, recover prior sessions, and index docs or notes so agents stop restarting cold.
Local-first deployment
Install via npm, use pre-built binaries, or run in Docker. Work over stdio or HTTP without shipping code to the cloud.
What you can ask
search() Recuperacion hibrida: semantica + palabras clave + grafo
impact() Inspecciona el radio de impacto antes de editar o refactorizar
code() Busqueda AST, patrones y reescrituras
commit_search() Busca en el historial git por significado
knowledge() Indexa docs y notas junto al codigo
restore() Recupera contexto de sesion y estado del proyecto

For large repositories
Search without brute-force reading
Hybrid retrieval and compact responses reduce how much irrelevant code an agent needs to scan before it can act.
For refactors
Check blast radius before edits
Call graph traversal, impact analysis, and git-aware search make shared changes safer before you touch production code.
For rollouts
Install it how your team works
Use the npm package, pre-built binaries, or the Docker image and keep the same local-first workflow across laptops and services.
