Quick Start

use agentmesh_mcp::{
    CredentialRedactor, InMemoryNonceStore, McpMessageSigner, McpSignedMessage,
    SystemClock, SystemNonceGenerator,
};
use std::sync::Arc;
use std::time::Duration;

let signer = McpMessageSigner::new(
    b"top-secret-signing-key".to_vec(),
    Arc::new(SystemClock),
    Arc::new(SystemNonceGenerator),
    Arc::new(InMemoryNonceStore::default()),
    Duration::from_secs(300),
    Duration::from_secs(600),
)?;

let signed: McpSignedMessage = signer.sign("hello from mcp")?;
signer.verify(&signed)?;

let redactor = CredentialRedactor::new()?;
let result = redactor.redact("Authorization: Bearer super-secret-token");
assert!(result.sanitized.contains("[REDACTED_BEARER_TOKEN]"));
# Ok::<(), agentmesh_mcp::McpError>(())
