render_diagram

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 the diagrams://reference/diagram, diagrams://reference/edge, and diagrams://reference/cluster resources for constructor options and usage examples. Args: code: Full Python code using the diagrams library. filename: Output filename without extension. format: Output format — ``"png"`` (default), ``"svg"``, or ``"pdf"``. download_link: If True, return a temporary download URL path (/images/{token}) that expires after 15 minutes; if False, return inline image bytes. Defaults to True (URL) — set ``DIAGRAMS_INLINE_DEFAULT=true`` on the server to flip the default. SVG/PDF and PNGs larger than the inline limit always use a download link.

list_providers

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.

No parameters.

list_services

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

list_nodes

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_nodes

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, provider, service, import, alias_of (optional). Sorted by relevance: exact match first, then prefix, then substring.

render_mermaid

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 edit link for opening the diagram in a browser editor. Args: definition: Mermaid diagram definition text. filename: Output filename without extension. format: Output format — ``"png"`` (default), ``"svg"``, or ``"pdf"``. download_link: If True, return a temporary download URL path (/images/{token}) that expires after 15 minutes; if False, return inline image bytes. Defaults to True (URL) — set ``DIAGRAMS_INLINE_DEFAULT=true`` on the server to flip the default. SVG/PDF and PNGs larger than the inline limit always use a download link.

render_plantuml

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 extension. format: Output format — ``"png"`` (default) or ``"svg"``. PDF is not supported (requires Batik/FOP). download_link: If True, return a temporary download URL path (/images/{token}) that expires after 15 minutes; if False, return inline image bytes. Defaults to True (URL) — set ``DIAGRAMS_INLINE_DEFAULT=true`` on the server to flip the default. SVG and PNGs larger than the inline limit always use a download link.

find_equivalent

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 mapped roles and pick a provider-specific node name. Args: node: Node class name to look up (case-insensitive, e.g. 'EC2', 'lambda'). target_provider: Optional provider to filter equivalents to (e.g. 'gcp', 'azure', 'aws'). If omitted, all equivalents across all other providers are returned. Returns: A dict with keys: category (str): Infrastructure role category name. description (str): Human-readable description of the category. source (dict): The matched node with keys node, provider, service, import. equivalents (list[dict]): Equivalent nodes, each with keys node, provider, service, import.

list_categories

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'). description (str): Human-readable description. providers (list[str]): Providers covered by this category. nodes (dict): Mapping of provider → list of node names in that category.

No parameters.
