# Keyblind — Blind AI to Your Keys

**Encrypted secrets vault with MCP for AI agents. One command configures every editor. Secrets resolved at runtime, never leaked to LLM conversations.**

[![License: MIT](https://img.shields.io/badge/License-MIT-green.svg)](LICENSE)

## Why

Developers regularly leak API keys, passwords, and tokens to AI coding tools. 100,000+ LLM conversations with exposed secrets were found indexed by search engines in 2025.

AI agents read your `.env` files. They copy-paste secrets into conversations. They commit them accidentally. Keyblind stops this by keeping secrets encrypted at rest and resolving them _at runtime_ — the plaintext value never touches the LLM transcript.

## How It Works

```
┌──────────┐     ┌────────────────┐     ┌─────────────────┐
│ AI Agent │ ──→ │  Keyblind MCP  │ ──→ │  Encrypted      │
│ (Claude) │     │  Server        │     │  SQLite Vault   │
│          │ ←── │  (27 tools)    │ ←── │  (AES-256-GCM)  │
└──────────┘     └────────────────┘     └─────────────────┘
      ↑                                        │
      │ secret value never appears             │ secrets never
      │ in conversation transcript             │ stored in plaintext
```

## Quick Start

```bash
# 1. Install
npm i -g keyblind

# 2. One-command setup (initialize vault + configure Claude Code)
keyblind quickstart

# 3. Store secrets
echo "sk-proj-abc123" | keyblind set OPENAI_API_KEY
keyblind set DATABASE_URL -    # prompts securely

# 4. Sandbox your .env (AI agents see fakes)
keyblind sandbox

# 5. Resolve a secret
keyblind get OPENAI_API_KEY

# 6. Run commands with secrets injected as env vars
keyblind run -- npm start

# 7. List all secrets (names only, values hidden)
keyblind list
```

> **That's it.** After `keyblind quickstart`, restart Claude Code. Then just say _"list my keyblind secrets"_ or _"use my OPENAI_API_KEY"_ — the AI agent resolves secrets at runtime without ever seeing them in the transcript.

## MCP Server

Keyblind is **MCP-first** — it works with every AI tool that speaks the Model Context Protocol (Claude Code, Cursor, Copilot, Windsurf, Cline, Zed).

### Setup (automatic)

```bash
keyblind setup-mcp
```

This auto-configures Claude Code, Cline, and Zed to use Keyblind. Works from any directory.

For project-local editors (Cursor, Windsurf, Copilot, Cline project mode), run from your project root:

```bash
keyblind setup-mcp --local
```

See [editor-specific configs](docs/editors.md) for details and manual setup.

### Setup (manual)

Add a `.mcp.json` to your project root, or use `claude mcp add`:

```bash
claude mcp add --scope user keyblind -- keyblind start
```

With biometric gate (Touch ID required before secrets are resolved):

```bash
keyblind unlock                      # Authenticate first
claude mcp add keyblind -- keyblind start --biometric
```

## Web Dashboard

Manage your secrets from a browser — **no sign-in or pairing required**. Open the local dashboard:

```bash
keyblind dashboard
```

This starts the local server and opens `http://localhost:4318/` in your browser. The dashboard is served same-origin with the REST API, so it works in every browser with no CORS, no pairing token, and no login. Features:

- View, add, copy, and delete secrets
- Audit log with full access history
- License management (tier, email, expiry)
- Pro/Team tier status
- Per-secret access policies and rotation reminders
- Agent action approvals (approve/deny queued agent writes)
- Central control plane (org-wide visibility + signed revocation)

A hosted control plane (`hosted/`) adds orgs, roles, groups, a signed
revocation + group-scope manifest, multi-provider SSO login (with org
auto-provisioning, multi-org switching, and IdP end-session revocation), and
short-lived agent credentials. See `docs/enterprise.md` (Phase 2).

## Browser Extension

The **Keyblind Chrome Extension** detects and blocks secrets from being pasted into AI chat interfaces (Claude.ai, ChatGPT, Copilot).

[![Chrome Web Store](https://img.shields.io/chrome-web-store/v/ljobkicejnncijfmnkkedpgngbaalnmd?label=Chrome%20Web%20Store&color=4285F4)](https://chromewebstore.google.com/detail/keyblind-%E2%80%94-blind-ai-to-yo/ljobkicejnncijfmnkkedpgngbaalnmd)

Features:
- Detects 12+ API key formats (OpenAI, GitHub, Stripe, AWS, etc.)
- Intercepts paste events on AI chat sites
- Warning banner when secrets are detected
- Popup with vault connection status

Located in `browser-extension/`. Load as unpacked extension from `chrome://extensions`.

- **Machine-identity-bound key** — encryption key XOR-wrapped with machine fingerprint
- **Zero network, zero telemetry** — no cloud, no accounts, no analytics
- **Vault stored at `~/.keyblind/`** with `0700` permissions
- **Deterministic sandbox fakes** using HMAC-SHA256 per project + key name

## Verifying Your Install

Releases are built and published from GitHub Actions with npm provenance, which
attests the tarball was produced from this repository's CI rather than a
developer machine.

```bash
npm audit signatures        # Verify npm registry signatures
```

To verify build provenance for a release, open the release page at
https://github.com/aarifmms/keyblind/releases and check the "Provenance" and
"Attestations" sections, which link the tarball to the exact commit and workflow
run that built it.

- **Small dependency graph** — the CLI depends on three packages only (MCP SDK,
  better-sqlite3, zod). Server-only deps (Stripe, Resend, the Vercel CLI) live in
  the `hosted/` and `dashboard/` packages and are not installed by
  `npm i -g keyblind`.
- **No source maps** — the published tarball ships compiled JavaScript with no
  embedded original source.
