Mike Params

Read and modify MIKE+ model parameters via the mike-plus MCP server — inspect or change values in any model table (pipe Diameter/Manning in msm_Link, node levels in msm_Node, catchment properties in msm_Catchment, etc.). Use when an agent must identify a current parameter and change it before re-running. Requires MIKE+ + license; mutating tools must run on a copy.

MIKE+ Parameters

Reads and edits values in the MIKE+ model database tables (via mikeplus). This is the "edit the model" capability that sits between mike-model (overview) and mike-runner (execute).

Tools

mike_get_values — {sqlite, table, columns?, muids?} → current values. Read-only. Use to identify a parameter before changing it.
mike_set_values — {sqlite, table, values, muids | all} → applies the change and returns before/after for the affected rows. Mutates the database.

Common tables / columns

msm_Link — pipes/reaches: Diameter, Width, Height, Manning (Manning's M; higher = smoother), MaterialID, TypeNo.
msm_Node — manholes/nodes: GroundLevel, InvertLevel, Diameter.
msm_Catchment — catchments: area / imperviousness / runoff parameters.
msm_Project — simulation setups (used by mike_run's simulation).

Conventions (safety)

Always operate on a COPY — mike_set_values writes to the database and mikeplus has no undo.
Scope every edit. Pass muids to target specific elements; only set all=true when you truly mean every row.
Confirm with the returned before/after (or a follow-up mike_get_values) before re-running.
Edit with the Base scenario active (or a scenario that shares Base's alternatives). Under a scenario with its own alternatives mikeplus cannot write and the tool errors "did not persist"; a variant for comparison is a second model COPY, not a scenario (see mike-compare).
Boundary/rain changes: the rainfall boundary is msm_BBoundary (TypeNo = 1; TSConnection = dfs0 path relative to the model folder, TimeseriesName = dfs0 item) — see mike-rain.
After editing, re-run with mike_run and quantify the effect with mike_results_compare (mike-compare).

Orchestration (identify -> change -> re-run -> compare)

mike_model_info / mike_get_values   -> identify current parameter
mike_set_values                     -> change it (on the variant copy)  -> before/after
mike_run                            -> new .res1d
mike_results_compare / mike_plot_compare -> against the baseline run
