Struct ArgumentAllowlist 

#[non_exhaustive]
pub struct ArgumentAllowlist {
    pub tool: String,
    pub argument: String,
    pub allowed: Vec<String>,
}

Per-tool argument allowlist entry.

When the middleware sees a tools/call for tool, it extracts the string value at argument from the call’s arguments object and checks its first token against allowed. If the token is not in the list the call is rejected with 403.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

tool: String

Tool name to match (exact or glob, e.g. "run_query").

argument: String

Argument key whose value is checked (e.g. "cmd", "query").

allowed: Vec<String>

Permitted first-token values. Empty means unrestricted.
