Examples.
Each example is a complete, runnable integration, installable from the handshake-protocol GitHub org. Walkthroughs ship alongside each SDK as it stabilizes.
Docs vs Spec. Docs explain how to use the SDKs to ship Handshake into your stack. The Spec is the protocol itself, the wire format, the algorithms, what every implementer must agree on. You read Docs once. You cite the Spec.
- MCP
Wrap an MCP server with handshake-mcp
Add the Handshake middleware to an existing FastMCP server. Verify the deployer chain on every tools/call and emit a signed receipt per invocation.
Walkthrough coming soon → - A2A
A2A peer-to-peer handshake
Two agents negotiate a delegated task across the A2A wire, each persisting receipts tied to the A2A task identifier for cross-org dispute resolution.
Walkthrough coming soon → - OpenAI
OpenAI Agents SDK adapter
Drop-in tool wrapper that issues a Handshake delegation per tool call, verifies the response receipt, and refuses tools the agent isn't authorized for.
Walkthrough coming soon → - LangGraph
LangGraph node with capability scoping
A graph node that takes a typed capability scope and emits a receipt as part of its output state, so downstream nodes can prove provenance.
