Fields

agent_id: String

agent_type: String

role: Option<String>

project_root: String

started_at: DateTime<Utc>

last_active: DateTime<Utc>

pid: u32

process_identity: Option<ProcessIdentity>

PID alone is not an identity: operating systems reuse it. The immutable process start marker prevents a retired MCP record from becoming “live” again when an unrelated process receives the same PID.

durable_identity_id: Option<String>

Optional explicit binding to the durable identity registry. Generated presence IDs remain independent and unchanged for legacy callers.

status: AgentStatus

status_message: Option<String>

transport: Option<TransportClient>

Present only on the presence an MCP server registers for its own connection. A transport stays listed while its process lives; worker leases (ctx_agent) expire independently of it.

role_source: Option<RoleSource>

Whether role was stated by the agent or its environment, or filled in by LeanCTX (placeholder, client-name heuristic, coder default).

parent: Option<String>

The presence this one was registered next to inside the same MCP process (a subagent shares its parent’s connection): it has its own id, so its reads never consume the parent’s directed messages.

app_session_id: Option<String>

The launching app’s session id (LEAN_CTX_SESSION_ID) of the process that registered this presence, so the app maps presences to its sessions without walking the process tree.

display_name: Option<String>

The name people see for this presence: ctx_agent register’s name, else the launching app’s session name (LEAN_CTX_SESSION_NAME). Display only, never an address or a role.
