Mongodb Atlas Admin

Manage MongoDB Atlas clusters, projects, users, backups, and alerts via the Atlas Admin API v2. Use when: (1) Creating, scaling, or deleting Atlas clusters, (2) Managing database users and IP access lists, (3) Configuring backups, snapshots, and restore jobs, (4) Setting up alerts and monitoring, (5) Managing projects and organizations, (6) Viewing cluster metrics and logs. Requires Atlas API keys (public/private) or service account credentials.

MongoDB Atlas Admin

Manage MongoDB Atlas infrastructure programmatically via the Atlas Administration API v2.

Authentication

Atlas API uses HTTP Digest Authentication with API keys or OAuth2 with service accounts.

API Keys (Legacy but simpler)

# Set credentials
export ATLAS_PUBLIC_KEY="your-public-key"
export ATLAS_PRIVATE_KEY="your-private-key"

# All requests use digest auth
curl --user "${ATLAS_PUBLIC_KEY}:${ATLAS_PRIVATE_KEY}" \
  --digest \
  --header "Accept: application/vnd.atlas.2025-03-12+json" \
  --header "Content-Type: application/json" \
  "https://cloud.mongodb.com/api/atlas/v2/..."

Service Accounts (OAuth2 - Recommended)

# Get access token
TOKEN=$(curl -s --request POST \
  "https://cloud.mongodb.com/api/oauth/token" \
  --header "Content-Type: application/x-www-form-urlencoded" \
  --data "grant_type=client_credentials&client_id=${CLIENT_ID}&client_secret=${CLIENT_SECRET}" \
  | jq -r '.access_token')

# Use token (valid 1 hour)
curl --header "Authorization: Bearer ${TOKEN}" \
  --header "Accept: application/vnd.atlas.2025-03-12+json" \
  "https://cloud.mongodb.com/api/atlas/v2/..."
