Try the Value Context Protocol in 30 seconds.
An interactive web tool for exploring the Value Context Protocol (VCP). Five tabs:
| Tab | Description |
|---|---|
| Decode | Paste a UVC token (VCP/I) or a creed:// / vcp:// URI, a CSM-1 code (NANO, MICRO, or COMPACT), an experimental WC/AS welfare snapshot (VCP/S v2.1 lines, a 3.2 candidate), or an Agent Runtime Profile JSON artifact, and get a field-by-field breakdown with syntax highlighting |
| Encode | Build a CSM-1 code (NANO or MICRO tier) interactively with live preview |
| Capability | Simulate capability negotiation — select extensions, see the VCP-Hello/VCP-Ack exchange and each extension's status (Stable, Draft, or Experimental) |
| Layers | The I-T-S-A-M-E six-layer stack and which layers the Inspector covers |
| Examples | Illustrative tokens and codes drawn from the VCP spec's examples |
- SvelteKit with static adapter (fully prerendered)
- Tailwind CSS for styling
- Zero backend — all VCP logic runs client-side in pure TypeScript
- Deployed on Vercel at inspector.valuecontextprotocol.org

npm run devRun the standalone test, coverage, type, and build gates with:
npm run validateAn optional cross-repository gate reads the current SDK fixtures and Spec schemas directly. It does not affect standalone validation:
npm run test:interop -- --sdk-root ../VCP-SDK --spec-root ../VCP-SpecVCP_SDK_ROOT and VCP_SPEC_ROOT provide equivalent path configuration.
