A sibling of @archsmith/cli, not a wrapper around it: both call render()/validate() from @archsmith/renderer directly. See the root README for the full picture.

Connecting it to an MCP host

Point the host at the built entrypoint, e.g. in Claude Desktop's claude_desktop_config.json:

{
  "mcpServers": {
    "archsmith": {
      "command": "npx",
      "args": ["-y", "@archsmith/mcp-server"]
    }
  }
}

Tools

render, validate, list_registries, get_registry — mirror the CLI's own commands (same validate-before-render behavior, same family filter on get_registry). render returns the SVG as both plain text and an image/svg+xml content block, so a client that renders arbitrary image mime types can show the diagram inline.

Resources

archsmith://schema and one archsmith://registries/<name> per governed registry — lets an agent authoring an IR read the live, current schema/registries directly instead of working from a stale copy baked into a prompt.
