HVTracker MCP

MCP server for checking supply-chain trust before connecting to AI agents, frameworks, or MCP servers.

The hosted remote server is:

{
  "mcpServers": {
    "hvtracker": {
      "url": "https://hvtracker.net/mcp"
    }
  }
}

This repository also provides a local stdio package for clients that prefer package-based installation.

Tools

• verify_mcp_server: pre-connect trust verdict for an MCP server, package, GitHub repo, or agent name.

• check_agent_trust: trust profile for a tracked AI agent or framework — incl. runtime capabilities (MCP status, providers, plugin surface, provenance drift) and the URL of its Ed25519-signed trust credential.

• compare_agents: two agents side by side with an evidence-based verdict and the published compare-page link.

• search_agents: search the HVTracker registry by name, repo, description, or category.

Registry Publishing

The server name is:

io.github.YugantM/hvtracker-mcp

Claude Desktop Extension

Tagged releases build an .mcpb bundle for Claude Desktop from manifest.json. To build it locally:

npm ci --omit=dev
npx @anthropic-ai/mcpb@2.1.2 pack

Privacy

HVTracker MCP sends the user-supplied search string or server identifier to https://hvtracker.net to fetch public trust data. It does not require an API key and does not write to user systems. See the HVTracker site for current data and methodology, and see PRIVACY.md for the repository privacy note.
