Generate infrastructure diagrams with 15+ providers (AWS, Azure, GCP, K8s, etc.).

Examples: AWS: nodes=[{"id":"r53","provider":"aws","category":"network","type":"Route53",...}] K8s: nodes=[{"id":"ing","provider":"k8s","category":"network","type":"Ingress",...}] Clusters: clusters=[{"name":"VPC","node_ids":["elb","ec2"],"graph_attr":{"bgcolor":"#E5F5FD"}}]

⚠️ CRITICAL: Node types must exist in diagrams library or diagram fails silently (no arrows). ALWAYS verify first: list_available_nodes(provider="aws", category="compute") For brands (Stripe, Vercel), use create_diagram_with_custom_icons instead.

Create diagrams with custom icons from web URLs or local files.

USE WHEN: Brand logos (Stripe, Vercel, Supabase, Fly.io) not in diagrams library. GitHub avatars work well: https://avatars.githubusercontent.com/u/{org_id}

Examples: URL: custom_nodes=[{"id":"stripe","icon_source":"url","icon_path":"https://avatars.githubusercontent.com/u/856813"}] Mixed: nodes=[{...AWS nodes...}], custom_nodes=[{...}], connections=[...]

HTTPS-only for URLs, 5MB limit, PNG/JPG supported. Automatic caching.

Discover 500+ node types across providers.

⚠️ USE THIS FIRST before create_diagram to avoid invalid node errors.

Filters: provider, category, search_term

Examples: AWS compute: provider="aws", category="compute" → EC2, Lambda, ECS, EKS... Search DBs: search_term="db" → RDS, DynamoDB, SQL across providers

Create process flowcharts with 24 shapes (StartEnd, Process, Decision, etc.).

Example: steps=[{"id":"start","shape":"StartEnd","label":"Start"},...] flows=[{"from_step":"start","to_step":"check"},...]

Validate diagram before generation (dry-run).

Checks: node validity, connection references, cluster memberships. Returns: {"valid": true/false, "errors": [...], "warnings": [...]}
