+#### `_meta`
+
+The `_meta` property/parameter is reserved by MCP to allow clients and servers
+to attach additional metadata to their interactions.
+
+Certain key names are reserved by MCP for protocol-level metadata, as specified below;
+implementations must not make assumptions about values at these keys.
+
+Additionally, definitions in the [schema](https://github.com/modelcontextprotocol/specification/blob/main/schema/draft/schema.ts)
+may reserve particular names for purpose-specific metadata, as declared in those definitions.
+
+**Key name format:** valid `_meta` key names have two segments: an optional **prefix**, and a **name**.
+
+**Prefix:**
+
+- If specified, must be a series of labels separated by dots (`.`), followed by a slash (`/`).
+  - Labels must start with a letter and end with a letter or digit; interior characters can be letters, digits, or hyphens (`-`).
+- The `modelcontextprotocol.[*]/` and `mcp.[*]/` prefixes are reserved for MCP use (where `[*]` stands for any top-level domain).
+
+**Name:**
+
+- Unless empty, must begin and end with an alphanumeric character (`[a-z0-9A-Z]`).
+- Could contain hyphens (`-`), underscores (`_`), dots (`.`), and alphanumerics in between.
