Data offered docs-verified: SWMM model input sections and values · SWMM model report sections · SWMM output variables and objects · rainfall timeseries plots · design storm modification (24-hour SCS Type 2) · conduit diameter and storage node changes · model runs
Formats llm-inferred: MCP stdio
Access docs-verified: Free and open source, MIT licence (per ENTRY metadata). Local install: clone the repository and run dependencies with uv. No auth.

Use cases llm-inferred: Testing design-storm depth scenarios on an existing SWMM drainage model · Identifying nodes that flood under a given storm for a drainage strategy review · Assessing detention storage placed at a node to reduce downstream flooding · Comparing base and modified outfall hydrographs for a drainage design option
Audience llm-inferred: drainage engineers · hydrologists · flood consultants · civils engineers

Constraints llm-inferred: Requires a local install (uv, cloned repository) and client configuration; not a hosted service · change_storm only sets a 24-hour SCS Type 2 design storm of a given depth · change_conduit only changes the diameter of circular conduits · add_storage replaces a junction with a cylindrical storage node · Tool argument schemas are not documented in DOCS · Claude Desktop on macOS may need a uv symlink to be found · No area or time-span coverage stated; depends on the SWMM models the user supplies
