export_artifact

Implementation Reference

• src/web_gui_mcp/mcp_tools.py:124-148 (handler)

  The export_artifact_handler function that executes the export logic: retrieves stored artifact, formats content as html/json/markdown/prompt, and returns ExportArtifactOutput.

  def export_artifact_handler(
      input_data: ExportArtifactInput,
      store: MemoryArtifactStore,
  ) -> ExportArtifactOutput:
      stored = store.get(input_data.artifact_id)
      if stored is None:
          raise ValueError(f"Unknown artifact_id: {input_data.artifact_id}")
      if input_data.format == "html":
          content = stored.html
      elif input_data.format == "json":
          content = json.dumps(
              stored.spec.model_dump(mode="json", by_alias=True),
              ensure_ascii=False,
              indent=2,
              sort_keys=True,
          )
      elif input_data.format == "markdown":
          content = export_markdown(stored.spec)
      else:
          content = export_prompt(stored.spec)
      return ExportArtifactOutput(
          artifact_id=stored.artifact_id,
          format=input_data.format,
          content=content,
      )

• src/web_gui_mcp/mcp_tools.py:192-195 (registration)

  The MCP tool registration for export_artifact inside register_tools(). Decorates a function with @mcp.tool() that delegates to export_artifact_handler.

  @mcp.tool()
  def export_artifact(input: ExportArtifactInput) -> ExportArtifactOutput:
      return export_artifact_handler(input, store)

• src/web_gui_mcp/schema/tool_io.py:132-134 (schema)

  class ExportArtifactInput(ToolBaseModel):
      artifact_id: str
      format: Literal["html", "markdown", "json", "prompt"]

• src/web_gui_mcp/schema/tool_io.py:137-140 (schema)

  ExportArtifactOutput schema: artifact_id (str), format (str), content (str).

  class ExportArtifactOutput(ToolBaseModel):
