Documentation

This index lists the DCP-AI documentation by task: getting started, architecture and security, testing, reference, operations, specifications and proposals. The current package versions for every registry are in Published versions.

Published versions

Verified on 28/10/2026. Package versions are independent of the DCP wire and specification version (2.0).

Registry	Package	Version	Release notes
npm	@dcp-ai/sdk (TypeScript SDK)	2.2.1	npm packages
npm	@dcp-ai/wasm	2.1.1	npm packages
npm	@dcp-ai/cli	2.1.1	npm packages
PyPI	dcp-ai (Python SDK)	2.10.1	Python release
Go modules	github.com/dcp-ai-protocol/dcp-ai/sdks/go/v2	v2.11.1	Go release
crates.io	dcp-ai (Rust SDK)	2.11.1	Rust release

• These versions verify the optional secondary SHA3-256 fields of V2-11 when they are present; absent fields are not required, so a verified bundle may lack a complete secondary chain, and a present inconsistent field is rejected. Earlier versions do not check them. The published adapters @dcp-ai/express, @dcp-ai/openclaw, @dcp-ai/anthropic-mcp and @dcp-ai/google-a2a 2.1.0 were not republished: they depend on @dcp-ai/sdk ^2.2.0 and get the secondary checks once your lockfile resolves @dcp-ai/sdk 2.2.1 or later.
• The npm adapters and scaffolders are optional and separate from the protocol core; their exact versions are in NPM_RELEASES.md, which lists all 13 npm packages.
• Affected earlier versions and upgrade notes are in SECURITY.md; moving from DCP v1.0 is covered by MIGRATION_V1_V2.md.
• In every SDK, dcp-jcs-v1 remains the normative and default canonicalization; the dcp-jcs-v2 APIs are experimental and opt-in. Verification does not establish principal trust, admission or authorization.
• This inventory covers the four registries above; it does not cover container images.

Quick Start

• QUICKSTART.md — Produce and verify evidence with an SDK (published packages or a source checkout); demos are marked separately
• QUICKSTART_EXPRESS.md — Express middleware integration
• QUICKSTART_LANGCHAIN.md — LangChain tool wrapping

Architecture & Security

• TECHNICAL_ARCHITECTURE.md — System architecture and deployment blueprint

• tests/interop/v2 — Shared vectors every SDK must accept or reject
• tests/interop/candidate/phase4 — Cross matrix of the experimental dcp-jcs-v2 producers (five SDKs)
