Struct AgentCard 

pub struct AgentCard {
    pub capabilities: Vec<String>,
    pub supported_protocols: Vec<ProtocolId>,
    pub metadata: HashMap<String, Value>,
    pub endpoint: Option<String>,
    pub max_concurrent_tasks: Option<usize>,
    pub compute_capacity: Option<f64>,
}

Capability advertisement for an agent.

Inspired by A2A’s AgentCard concept — describes what an agent can do, which protocols it speaks, and how to reach it.

Fields

capabilities: Vec<String>

High-level capabilities this agent offers (e.g. "code-review", "file-editing", tool names).

supported_protocols: Vec<ProtocolId>

Protocol identifiers this agent supports (e.g. "mcp", "a2a", "ipc").

metadata: HashMap<String, Value>

Arbitrary key-value metadata (e.g. model name, version, region).

endpoint: Option<String>

Network endpoint if the agent is directly reachable (e.g. "tcp://192.168.1.5:9090" or "unix:///tmp/agent.sock").

max_concurrent_tasks: Option<usize>

Maximum number of tasks this agent can handle concurrently.

compute_capacity: Option<f64>

Abstract compute capacity score (higher is more powerful).

Implementations

impl AgentCard

pub fn supports_protocol(&self, protocol: &str) -> bool
