It uses Optuna's visualization module to create a timeline plot of the study and returns it as a PNG image via FastMCP's Image type.@mcp.tool() def plot_timeline() -> Image: """Return the timeline plot as an image.""" fig = optuna.visualization.plot_timeline(mcp.study) return Image(data=plotly.io.to_image(fig), format="png")
- optuna_mcp/server.py:686-686 (registration)The register_tools function (lines 100-669) registers all tools including plot_timeline via @mcp.tool() decorators, and it is called here in main() to register the tools on the MCP server instance.mcp = register_tools(mcp)
