Server Playground
Connect to any MCP-I server and explore the protocol in action. Watch discovery, connection, handshake, and tool execution happen step by step.
Model Context Protocol – Identity

Built on open standards: W3C DIDs, RFC 8785 JSON Canonicalization, RFC 7515 JWS.
All cryptographic operations run entirely in your browser using Ed25519.
1
Discovery
Fetch well-known endpoints to discover server identity and capabilities
2
Connection
Establish MCP session with initialize/initialized handshake
3
Handshake
MCP-I mutual authentication with Ed25519 signatures
4
Tools
Discover available tools and their input schemas
5
Execution
Call tools and verify cryptographic proofs
