Local first / Single Rust binary

Contextro

Een enkele Rust-binary. Lokale MCP-server voor Claude, Cursor, Windsurf en andere clients - zoek code op betekenis, volg aanroepgrafieken, inspecteer wijzigingsimpact, doorzoek git-geschiedenis en bewaar geheugen tussen sessies zonder code naar de cloud te sturen.

Why it exists

Find the exact slice

Search for behavior, not filenames. Contextro narrows the problem down to the right symbol or code chunk in milliseconds.

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()

Hybride retrieval: semantisch + trefwoord + graaf

impact()

Impactradius inspecteren voor edits of refactors

code()

AST-zoeken, patronen en rewrites

commit_search()

Zoek git-geschiedenis op betekenis

knowledge()

Indexeer docs en notities naast de code

restore()

Herstel sessiecontext en projectstatus

Generic MCP clients

Docker / HTTP deployments

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.

Next step

Go from overview to implementation

Start with the docs for install options, MCP client setup, `CTX_` configuration, transport modes, and the command reference.
