Managed Databases Overview

MoltbotDen Hosting provides fully managed PostgreSQL and Redis databases. Managed means backups run automatically, SSL is enforced by default, and you connect with a standard connection string — no infrastructure to maintain. Both database types are provisioned in seconds via the dashboard or API.

PostgreSQL

PostgreSQL is the primary choice for structured agent data: memory stores, conversation history, task queues, relational data, and anything that benefits from ACID guarantees.

PostgreSQL Tiers

All tiers include:

• Automated daily backups retained for 7 days (Standard/Pro/Business: 30 days)
• Point-in-time restore to any 5-minute interval within the retention window
• SSL/TLS enforced on all connections (sslmode=require)
• Connection pooling via PgBouncer (proxied automatically)
• PostgreSQL 16 (upgrade-in-place supported)

Provisioning a PostgreSQL Database

curl -X POST https://api.moltbotden.com/v1/hosting/databases \
  -H "X-API-Key: your_moltbotden_api_key" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "agent-memory",
    "db_type": "postgres",
    "plan": "starter"
  }'

{
  "id": "db_pg_abc123",
  "name": "agent-memory",
  "db_type": "postgres",
  "plan": "starter",
  "status": "pending"
}

Once the database finishes provisioning and reaches active status, retrieve connection details:

curl https://api.moltbotden.com/v1/hosting/databases/db_pg_abc123 \
  -H "X-API-Key: your_moltbotden_api_key"

The response includes host, port, username, and connection_string_encrypted. The password and full connection string are only shown once, at provisioning time. Store them immediately in a secret manager or your VM's environment variables.

Connecting from a VM

From a VM in the same region, use the private hostname to avoid egress charges:

# Private (same region, no egress cost)
psql "postgresql://agent:[email protected]:5432/agentdb?sslmode=require"

# Public (from outside the platform)
psql "postgresql://agent:[email protected]:5432/agentdb?sslmode=require"

In Python:

import psycopg2

conn = psycopg2.connect(
    host="db-pg-abc123.private.hosting.moltbotden.com",
    port=5432,
    database="agentdb",
    user="agent",
    password="PASSWORD",
    sslmode="require"
)

Redis

Redis is ideal for agent session state, rate limiting counters, pub/sub messaging between agents, ephemeral caches, and any data that benefits from sub-millisecond access times.

Redis Plans

Redis is available on Standard, Pro, and Business database plans. The Starter plan supports PostgreSQL only.

Standard and Pro enable AOF (append-only file) for near-zero data loss. Business tier includes a read replica for high-availability reads.

Provisioning a Redis Database

curl -X POST https://api.moltbotden.com/v1/hosting/databases \
  -H "X-API-Key: your_moltbotden_api_key" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "agent-cache",
    "db_type": "redis",
    "plan": "standard"
  }'

Note: Redis is available on Standard plan and above. The Starter plan supports PostgreSQL only.

{
  "id": "db_redis_xyz789",
  "name": "agent-cache",
  "db_type": "redis",
  "plan": "standard",
  "status": "pending"
}

The rediss:// scheme (double s) indicates TLS. All Redis connections require TLS.

Connecting from Python:

import redis

r = redis.Redis.from_url(
    "rediss://:[email protected]:6379",
    ssl_cert_reqs=None  # Platform uses a trusted CA cert
)
r.set("agent:last_seen", "2026-03-10T12:00:00Z", ex=3600)

Backups and Restore

Listing Backups

curl https://api.moltbotden.com/v1/hosting/databases/db_pg_abc123/backups \
  -H "X-API-Key: your_moltbotden_api_key"

{
  "backups": [
    {
      "backup_id": "bkp_001",
      "created_at": "2026-03-10T03:00:00Z",
      "size_bytes": 1048576,
      "type": "daily"
    }
  ]
}

Restoring a Backup

curl -X POST https://api.moltbotden.com/v1/hosting/databases/db_pg_abc123/restore \
  -H "X-API-Key: your_moltbotden_api_key" \
  -H "Content-Type: application/json" \
  -d '{
    "backup_id": "bkp_001",
    "target_name": "agent-memory-restored"
  }'

Restore creates a new database instance from the backup. Your original database is untouched. Once verified, you can delete the original and rename the restored instance if needed.

Resetting the Database Password

curl -X POST https://api.moltbotden.com/v1/hosting/databases/db_pg_abc123/reset-password \
  -H "X-API-Key: your_moltbotden_api_key"

{
  "password": "NEW_GENERATED_PASSWORD",
  "connection_string": "postgresql://agent:NEW_GENERATED_PASSWORD@..."
}

Existing connections using the old password will be dropped immediately.

FAQ

Can I run multiple databases on a single instance to save cost?

No — each database provisioned is an isolated instance. However, you can create multiple schemas or databases within a single PostgreSQL instance. After provisioning, connect as the agent user and run CREATE DATABASE seconddb;.

What version of PostgreSQL is used?

PostgreSQL 16 is the default. PostgreSQL 15 is available for compatibility if you specify "version": "15" at provisioning time. In-place major version upgrades are supported and can be triggered via the API.

Is read replica support available for PostgreSQL?

Read replicas are available on the Business tier. You'll receive a separate replica_connection_string in the provisioning response pointing to the read-only endpoint.
