+Each tool's `family` is its server label. Its `tags` are
+`mcp.server:<label>`, `mcp.server_id:<id>` and `mcp.tool:<remote name>`, so a
+host's `tinytools::ToolRules` can target one server's tools by the names the
+server uses. The label in `mcp.server:` is the configured one, not the
+sanitized `family` (`{ "tags": "mcp.tool:delete*" }`). The registered name is a slug
+with a digest suffix, which a pattern cannot reliably split. The per-server
+`allowed_tools` / `disallowed_tools` lists stay exact, fetch-time filters
+inside the registry.

 ## Exposure and execution
 
 `McpExposure` controls whether tools are offered directly or deferred for tool
