Struct BearerAuth 

pub struct BearerAuth { /* private fields */ }

Bearer token authenticator for MCP HTTP transport.

Implementations

impl BearerAuth

pub fn new(token: impl Into<String>) -> Self

Create a new bearer auth with the given token.

pub fn generate() -> Self

Generate a random bearer token (128 bits of OS entropy, hex-encoded).

Uses the OS CSPRNG via getrandom. If the OS entropy source is unavailable the call fails rather than falling back to a guessable token — see BearerAuth::try_generate.

Panics

Panics if the OS entropy source is unavailable. Use BearerAuth::try_generate to handle that case, or BearerAuth::new to supply an externally generated token.

pub fn try_generate() -> Result<Self>

Fallible BearerAuth::generate — never falls back to a weak token.

pub fn validate(&self, header_value: &str) -> bool

Validate a bearer token from an Authorization header.

The auth scheme is matched case-insensitively, as RFC 7235 requires (bearer x and Bearer x are equivalent).

pub fn token(&self) -> &str

Get the raw token value.

Trait Implementations

impl Debug for BearerAuth

Deriving Debug would print the token into logs and panic messages.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
