Expand description

Trait for dynamic token providers.

Implement this to provide bearer tokens that are acquired and refreshed at runtime (e.g., via OAuth 2.0 grants).

§Example

use async_trait::async_trait;
use tower_mcp::client::{TokenProvider, OAuthClientError};

struct StaticTokenProvider(String);

#[async_trait]
impl TokenProvider for StaticTokenProvider {
    async fn get_token(&self) -> Result<String, OAuthClientError> {
        Ok(self.0.clone())
    }
}
