Common questions
Is Obra Cto safe?
It passed 0 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?
The registry does not list a required key, though some servers ask you to sign in on first use.
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 (0.3.0) reached the registry 4 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.
What can I use instead?
In the same category: GitHub, Desktop Commander, Cloudflare MCP

Obra CTO
A local-first MCP server that scores your codebase's Build Readiness. You install it in your own Claude. Your Claude reads your code on your machine and runs your tests there. Nothing is uploaded.
This is the free preview of Obra's role lineup, and it stays free and local. The CTO reads your code and tells you what an investor's technical diligence would find: real security holes, weak design decisions, and the gaps that stop a serious review. The rest of the team (the Obra CFO for funding-ready materials, and more) lives in the Build with Obra community.
The Obra founders' toolkit
Two free, local, open-source MCPs built to work as a pair:
- Obra CTO (this one): is it built? Scores your codebase and surfaces what a technical diligence would flag. GitHub · npm
- Obra CFO: is it fundable? Runs the investment committee on your pitch and turns your verified build into a funding case. GitHub · npm
Run the CTO first. The CFO reads its report as grade-A technical evidence. The method, the deep versions, and Obra in beta live in Build with Obra.
Why local-first
A tool that reads your code should not ship your code somewhere. Your source never leaves your machine. This server makes exactly one kind of network call, and only when you run the dependency check: it sends your package names and versions to the OSV vulnerability database, never a line of your code (you can see the single call in src/deps.ts). Everything else is local: it returns counts, presence flags, a redacted secrets scan, and a score. You can read every line of this server before you run it, which is the point of keeping it open.
What you get
The Obra CTO Score, out of 100, calibrated to your stage (prototype, MVP, or growth), across six dimensions:
| Dimension | Weight |
|---|---|
| Security | 25 |
| Product reality (what is actually built) | 20 |
| Robustness | 15 |
| Architecture | 15 |
| Maintainability | 15 |
| Deploy readiness | 10 |
Every finding carries an evidence grade: A verified, B multiple sources, C partial or inferred, D claim only, E speculation. The score is built from grade A and C evidence, what is true in your code, not what a deck says. When the CTO runs your tests and they pass, reliability becomes grade A. A deck-scorer can never earn that.
What a run looks like
Point it at a real project and you get a scored report with a ranked risk register. Here is a run on a scrappy Supabase app (anonymized):
# Obra CTO Score: financeapp46 / 100 · Not yet ready
Assessed as: mobile (react-native, expo) | Backend: supabase
| Dimension | Score | Evidence |
|---|---|---|
| Security | 6/25 | A |
| Product reality | 20/20 | A |
| Robustness | 3/15 | A |
| Architecture | 9/15 | A |
| Maintainability | 6/15 | A |
| Deploy readiness | 2/10 | C |
Top Risks
- [critical] RLS policies defined but never enabled; data may be open to any authenticated user Fix: enable row level security on every table, then verify a second user cannot read your rows.
- [high] Access control gap: a privileged action checks only that the user is logged in, not that they own the resource
- [medium] No tests found
On a well-built app it scores high and credits the good engineering. It is calibrated, not a fear machine.
Tools
scan_projectreads the project and returns mechanical signals.check_dependencieschecks your locked dependencies against the OSV vulnerability database. Only package names and versions leave your machine, never your code.run_testsruns your test suite (this executes code, so your Claude asks first) and parses the pass and fail counts.prepare_code_reviewselects your highest-signal files (schema and policy files, entry points, security-relevant code) and hands them to your Claude with a checklist tuned to your stack, including a Backend-as-a-Service lens (Supabase, Firebase) and a design red-team that critiques the architecture, not just the code.score_build_readinessproduces the Obra CTO Score with a Top Risks register.
A normal run is: scan, check dependencies, run tests, prepare the code review, then score.
Install
Add it to your Claude MCP config (Claude Desktop or Claude Code):
{"mcpServers": { "obra-cto": { "command": "npx", "args": ["-y", "obra-cto"] } } }
Then ask your Claude: "Score this project's build readiness with Obra CTO."
Prefer to run from source? Clone the repo, run npm install && npm run build, and point the config at node /absolute/path/to/obra-cto/dist/index.js.
What this is not
Not a linter, not a security scanner, not a replacement for your own Claude reading the code. It is technical-diligence readiness inside funding readiness: the question an investor's CTO would ask, answered from your real code.
What's next
The Obra CTO is the free preview. To go further:
- The Method: the full playbook for shipping production software with AI, the disciplines that make code score like the example above, each lesson with a paste-in prompt or tool you can use today.
- The rest of the team: the Obra CFO for funding-ready materials, and each new role as it ships.
- Obra itself, in beta: the AI employee that runs your back office. Members go first.
