GroupMixer

Create or update a GroupMixer scenario. Use this same tool for ordinary rotations and constrained scenarios. For creation provide name and scenario with people (stable id; attributes optional), groups (id and capacity), and session_count. For edits supply workspace_id and expected_revision from current shared context, then ONLY the fields to change. Omitted fields are preserved. Arrays replace the corresponding complete list; person_names and group_names merge by ID. Use [] to clear objectives or constraints. To minimize repeated pairings, objectives:[{"type":"avoid_repeats"}] is sufficient: threshold 1, squared curve and weight 1 are documented defaults; these penalize repeats without imposing a hard cap. The browser applies valid requests automatically by default, including workspace creation; review is an opt-in user preference. This tool never generates groups. Remote responses await delivery to the browser: present review_url unchanged as an Open in GroupMixer link if the host does not deliver the request. Only browser acknowledgement or updated workspace context confirms application.

groupmixer_prepare_scenario

Open the GroupMixer editor to prepare groups, run the local browser solver, inspect results, and export. Requires an interactive MCP Apps host; does not solve on the server.

groupmixer_open_workspace

Navigate to any scenario workspace route, including every setup section, solver settings, saved result analysis, comparisons, exports and manual editing. Prefer groupmixer_navigate_in_workspace when available for direct navigation. This stateless tool returns a navigation request and navigation_url; present that exact link if the host does not deliver the request to the open app. Do not claim navigation completed until the browser confirms it. Does not edit data, grant access, generate results or share a workspace.
