Description
Connect SeatCanvas, a free drag-and-drop seating-chart planner for weddings and events to your AI assistant. Three read-only tools answer seating questions and hand you a ready-to-edit plan via a prefilled planner link. No account needed to view a plan; nothing is saved until you sign in. **Tools** - `seatcanvas_get_pricing` — free-tier limit + one-time Event Pass price. - `seatcanvas_estimate_capacity` — how many guests a venue (W×H) seats at a chosen table type, plus a prefilled plan link. - `seatcanvas_create_plan` — a prefilled table layout for a given guest count and event type.

Agent readability score
Can an LLM agent pick the right tool here — names, descriptions and parameter clarity are assessed.
Agent readability score
Strengths
- Tool names clearly indicate their purpose (e.g., 'get_pricing', 'estimate_capacity').
- Descriptions mention read-only nature and deterministic outputs for clarity.
Weaknesses
- Tool names like 'seatcanvas_create_plan' are misleading since it generates a link, not a plan.
- Parameter definitions (e.g., 'table type', 'venue dimensions') lack specificity in descriptions.
- No explicit error handling or constraints mentioned in tool descriptions.
seatcanvas_create_plan— Name suggests creation, but tool only generates a prefilled link (no actual plan creation).seatcanvas_estimate_capacity— Description mentions 'table type' but doesn't clarify available options or input format.
