What It Does

An interactive web tool for exploring the Value-Context Protocol (VCP). Four tabs:

Tab	Description
Decode	Paste any VCP token — get a layer-by-layer breakdown with syntax highlighting
Encode	Build a CSM-1 token interactively with live preview
Capability	Simulate capability negotiation — select extensions, see VCP-Hello/VCP-Ack exchange
Examples	Pre-loaded tokens from real use cases drawn from the VCP spec

Tech Stack

• 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

Development

npm install
npm run dev

Run the standalone test, coverage, type, and build gates with:

npm run validate

An 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-Spec

VCP_SDK_ROOT and VCP_SPEC_ROOT provide equivalent path configuration.
