Diagrams MCP

Render a mingrammer/diagrams Python snippet to PNG and return the image. The code must be a complete Python script using `from diagrams import ...` imports and a `with Diagram(...)` context manager block. Use search_nodes to verify node names and get correct import paths before writing code. Read

List all available diagram providers (aws, gcp, azure, k8s, onprem, etc.). Use list_providers -> list_services -> list_nodes to browse available node types for a specific provider.

List service categories for a provider (e.g. 'aws' -> ['compute', 'database', ...]). Args: provider: Provider name from list_providers (e.g. 'aws', 'gcp', 'k8s').

List available node classes for a provider.service combo. Args: provider: Provider name (e.g. 'aws', 'gcp', 'k8s'). service: Service category (e.g. 'compute', 'database', 'network'). Returns: List of nodes with keys: name, import, alias_of (optional).

Search for diagram nodes by keyword across all providers and services. For targeted browsing when you know the provider, use list_providers -> list_services -> list_nodes instead. Args: query: Search term (case-insensitive substring match). Returns: List of matching nodes with keys: node,

Render a Mermaid diagram definition and return the image with metadata. The definition should be valid Mermaid syntax (e.g. flowchart, sequence, class, ER, state, or Gantt diagram). Returns a list of content blocks: the rendered image plus a JSON text block with metadata including a mermaid.live e

Render a PlantUML diagram definition and return the image. The definition should be valid PlantUML syntax wrapped in @startuml/@enduml (sequence, class, component, activity, state, deployment, etc.). Args: definition: PlantUML diagram definition text. filename: Output filename without exte

Find cross-provider equivalents for a diagram node by infrastructure role. Given a node name (e.g. 'EC2', 'Lambda', 'ComputeEngine'), returns the infrastructure role category it belongs to and the equivalent nodes from other providers. If a node name is ambiguous, use list_categories to see all ma

List all infrastructure role categories with their mapped nodes. Use this to browse all available equivalence mappings, or to disambiguate node names when find_equivalent reports ambiguity. Returns a list of category dicts, each with: category (str): Category identifier (e.g. 'virtual_machine'
