Common questions
Is Oko safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
You need to fill in: TYPESAFE_API_KEY
Does it run on my computer or in the cloud?
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?
The GitHub repo last changed –, and the latest version (0.9.1) reached the registry 17 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need MCPB on your computer.
What can I use instead?

Oko
Help your coding agent find code faster and use fewer tokens.
Oko gives Claude Code, Codex, Cursor, OpenCode and Pi a better code search. When you ask your agent about your code, Oko has already found the relevant source, so the agent spends fewer rounds searching and reading files it does not need.
Nine coding tasks on Astro, HTTPX and ripgrep, three runs each, with and without Oko. Results · Method
- Faster: about half the time in Claude Code, OpenCode and Pi; a quarter less in Codex.
- Cheaper: 33–44% fewer tokens with every tool we measured.
- Fewer detours: 65–89% fewer tool calls.
- Better ranking: puts the right file first more often than any published method on Agent Retrieval Bench.
- Local first: search runs on your machine; only the question and selected snippets go to the ranker (privacy).
Quick start
brew install bartlomein/tap/okocd your-project oko setup --client claude # or codex, cursor, opencode, pi, all
Without Homebrew: curl -fsSL https://raw.githubusercontent.com/bartlomein/oko/main/install.sh | sh.
Then use your coding tool as usual. Setup asks for a TypeSafe AI key the first time, connects your tool to Oko for this project, and checks the connection. Run it once per project; oko upgrade keeps everything current (with Homebrew, run brew upgrade oko first).
Codex: approve Oko's hook once
The first time you open the project, Codex shows Hooks need review. Choose Trust all and continue. If you skipped it, /hooks brings it back.
Cursor: turn Oko on once
Cursor adds a project's tools switched off. Open Customize > MCPs, click oko and turn it on.
Pi: trust the project
Pi 1.0 or later. Trust the project when Pi asks, then check /mcp. Pi setup.
Claude Code, OpenCode: nothing more to do
Start a new session after setup.
Platforms, manual install, no-key mode
macOS (Apple Silicon and Intel) and Linux (ARM64 and x64, glibc 2.35+). The installer puts oko in ~/.local/bin; add it to your PATH if needed. Other install options · Connect a tool by hand · Keys and configuration. For search without a key, add --no-jev: local keyword ranking only.
Results
The same task given to the same coding tool twice, once with its own search and once with Oko, in the same run. Means per session.
| Coding tool | Time | Tokens | Tool calls | Tasks passed (without → with) |
|---|
| Claude Code | 47% less 12.1 → 6.4 s | 44% less 24,271 → 13,627 | 89% less 3.5 → 0.4 | 19 → 20 of 20 | | Codex | 26% less 13.8 → 10.2 s | 43% less 45,395 → 26,004 | 80% less 3.0 → 0.6 | 20 → 20 of 20 | | OpenCode | 47% less 18.0 → 9.6 s | 43% less 13,196 → 7,528 | 87% less 3.7 → 0.5 | 21 → 21 of 21 | | Pi | 51% less 16.7 → 8.2 s | 33% less 9,737 → 6,495 | 85% less 3.6 → 0.5 | 20 → 21 of 21 | | Cursor | 6% less 52.3 → 49.2 s | 40% less 182,940 → 109,520 | 65% less 8.0 → 2.8 | 26 → 24 of 27 |
Models: Claude Sonnet 5.5 (Claude Code), GPT-6.1 Sol (Codex, OpenCode, Pi), Grok 4.7 High (Cursor), at their default or low effort. Cursor's row is from its own run on the previous release; the others are from October 2026. Each tool counts tokens its own way, so compare within a row. Small benchmark; your results will vary.

Other benchmarks
| Benchmark | What it tests | Oko | Best comparison |
|---|---|---|---|
| Sense's agent benchmark | Six multi-step tasks, Claude Opus 4.7, run against Sense the same evening | Found 88% of the locations to cite, at half the cost | Sense: 63% |
| Agent Retrieval Bench | 345 tasks: find the files a developer needs next | Right file ranked first most often: 0.40, checked by the benchmark's maintainers | Best published method: 0.24 |
| SWE-Explore | 848 real issues: rank the code fixing agents needed | One search ranks it within the range of agents that explore for many turns: 0.82 | Agents: 0.72–0.95 |
Where Oko helps less
- Cursor's own search is already fast, so Oko saves less time there: mostly tokens and tool calls.
- Duplicated code can mislead it. When two files hold identical copies of a function, Oko may show the wrong one first; one Astro edit task in our benchmark fails this way.
- Big changes across many files: one search returns five places, so an issue touching many files still needs the agent's own exploring.
Use it from your terminal

More in search options.
How it works
Oko searches your project locally (keywords, symbols and file structure), then asks Jev, TypeSafe AI's relevance model, which of the candidates actually answer the question, and returns those excerpts with exact line numbers. oko setup connects it to your tool as an MCP server, adds short guidance to the instructions your tool reads, and installs a hook that answers a code question as you send it.
