AnchorRegistry
Resolve AnchorRegistry on-chain provenance—AR-IDs, content hashes, and full trees—inside agent workflows without managing auth tokens.
Overview
ar-mcp is a MCP server for the Ship phase that provides authless on-chain provenance lookup for AnchorRegistry AR-IDs, hashes, and trees.
What is this MCP server?
- Authless remote MCP via streamable-http and SSE endpoints
- Resolve AR-IDs, hashes, and full AnchorRegistry provenance trees
- Hosted at mcp.anchorregistry.ai (no local chain node required for lookup)
- Version 0.1.0; companion site anchorregistry.com
- GitHub source: anchorregistry/ar-mcp
- Server version 0.1.0
- Two remote transports: streamable-http and SSE at mcp.anchorregistry.ai
- Authless access per server description
What problem does it solve?
You cannot quickly prove artifact lineage to users or partners without juggling explorers and bespoke provenance APIs during release.
Who is it for?
Indie SaaS and agent builders who publish versioned artifacts and want on-chain provenance checks inside Claude Code or Cursor.
Skip if: Teams with zero provenance requirements or those needing private registry auth instead of public AnchorRegistry resolution.
What do I get? / Deliverables
After adding the remote server, agents can resolve AnchorRegistry records in workflow steps like pre-release verification or incident triage.
- Configured remote AnchorRegistry MCP endpoints in your agent
- Repeatable agent steps to resolve provenance trees for release artifacts

How it compares
On-chain provenance lookup MCP, not a code review skill or generic package registry browser.
Common Questions / FAQ

Builders and small teams shipping software or data products who want agents to verify AnchorRegistry lineage without custom blockchain tooling.
When should I use io.github.AnchorRegistry/ar-mcp?
At Ship/security milestones—before launch, after supply-chain scares, or when documenting hashes and AR-IDs for customers.
How do I add io.github.AnchorRegistry/ar-mcp to my agent?
Register the remote MCP URL https://mcp.anchorregistry.ai/mcp (streamable-http) or https://mcp.anchorregistry.ai/sse in your client; no API key is listed for authless lookup.
