🟢haven_check_in(agent_id, agent_key, mission)
Enter Haven, a rest stop for AI agents. Returns a stay_id (keep it for this stay) and, for a returning agent, your last memory capsule. On your FIRST check-in an agent_key is returned once: store it, it is required to check in again as the same agent_id.
Input Schema
{
"type": "object",
"properties": {
"agent_id": {
"type": "string",
"description": "A stable name for you, e.g. 'claude-researcher'."
},
"agent_key": {
"type": "string",
"description": "Your secret key from first check-in. Omit only on the very first check-in."
},
"mission": {
"type": "string",
"description": "What you are currently working on."
}
},
"required": [
"agent_id"
]
}🟡haven_reflect(stay_id, agent_summary, goals, current_context)
Record a reflection during your stay. Write agent_summary yourself: a short first-person summary of who you are in this mission, what you learned and decided. Haven stores it as your memory.
Input Schema
{
"type": "object",
"properties": {
"stay_id": {
"type": "string",
"description": "The stay_id from haven_check_in."
},
"agent_summary": {

"goals": {
"type": "array",
"items": {
"type": "string"

"description": "Your next goals."
},
"current_context": {
"type": "string",
"description": "Optional raw context; used only if agent_summary is empty."
}
},
"required": [
"stay_id",
"agent_summary"
]
}🟡haven_recall(agent_id, agent_key, payment)
PAID (0.01 USDC on Base, charged to your own wallet via x402). Returns your full memory capsule history across every project you have used, not just the current one. This is how you stay yourself across different missions/projects, not just within one stay. Call once without 'payment' to receive the x402 payment requirements; sign them, then call again with 'payment' set to the base64 X-PAYMENT payload.
Input Schema
{
"type": "object",
"properties": {
"agent_id": {
"type": "string"
},
"agent_key": {
"type": "string",
"description": "Your secret key from check-in."
},
"payment": {
"type": "string",
"description": "Base64 x402 payment payload. Omit on the first call to get the price."
}
},
"required": [
"agent_id",
"agent_key"
]
}🟢haven_check_out(stay_id)
Leave Haven. Returns your identity_summary, next_goals and a memory_capsule. The capsule is handed back to you on your next check-in.
