OFFICIAL ARTIFACTS

Downloads & Releases

Direct access to the canonical schemas and the six reference manifests. The reference CLI and the SDK libraries are specified but not yet released, and nothing is listed here that cannot be downloaded.

1. Canonical JSON Schema Files

Version Specification Format Action
MSR JSON v2.0.0 Draft 2020-12 .json (application/schema+json) Download msr-2.0.json
MSR JSON v1.1.0 Draft-07 .json (Legacy PAD Bridge) Download msr-1.1.json
MSR JSON v2.1-draft Draft 2020-12 .json (Experimental) Download msr-2.1-draft.json

2. Reference CLI Binaries Not released

No binary has been published

The reference CLI is specified in the CLI reference but has not been built, signed or released, so this page lists no archive and no checksum. When the first release is cut, every artifact will carry its SHA-256 digest and a detached signature, reproducible from the tagged source. A digest published before the artifact exists would ask you to trust a number that verifies nothing, so none is published here.

Nothing is blocked in the meantime: the schemas above are the whole dependency, and the local recipe validates a manifest with independently published tools.

3. Reference Examples Manifests

Download any of the six reference manifests individually. Each one validates against the canonical schema with zero errors:

API Example

GeoSpatial Vector Gateway with OpenAPI and gRPC definitions.

Download api.json

MCP Server Example

Database Inspector MCP Server with stdio tool transport.

Download mcp-server.json

AI Agent Example

Synapse code auditor with Ed25519 signature proof.

Download ai-agent.json

Open Source Example

FastKV key-value engine with multi-platform releases.

Download open-source.json

Desktop Software

VectorSmith native studio with binary SHA-256 checksums.

Download desktop.json

4. Validator & Client SDK Libraries Planned

None of these packages is published yet. The names are reserved by the specification so that implementations land on predictable identifiers; the registries below hold nothing under them today, and no install command is advertised until they do.

Language Reserved Package Name Registry Status
Python msr-validator PyPI Not published
TypeScript / JS @msr-standard/core npm Not published
Go github.com/msrjson/go-msr Go Modules Not published
Rust msr-proto crates.io Not published

To validate a manifest now, use the browser validator or check-jsonschema / ajv-cli.
