Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Altessa plans wedding receptions. Four tools: plan_reception_layout (room fit, tables, dance floor, bar), generate_seating_chart (assign named guests to tables with keep-together and keep-apart rules), build_wedding_timeline (minute-by-minute wedding day schedule from a ceremony time), estimate_wedding_budget (category split from a total or guest count). Ask at most one clarifying question before calling a tool; use defaults otherwise. Each result includes a view-only link the user can open to keep editing. Do not describe plans, pricing, or purchases. Units are feet and US dollars.

plan_reception_layout — Reception layout planner

Advertised by the server during the last successful anonymous check.

Use this when someone wants to plan a wedding reception floor plan, figure out how many tables fit in a room, or check whether a venue space can hold their guest count with a dance floor, bar, buffet, DJ or band, and head table. Needs guest count; room dimensions in feet are optional (if missing, returns the space required instead of a fit check). Do not use for ceremony seating, seating assignments by name (use generate_seating_chart), or venue search.

generate_seating_chart — Seating chart generator

Advertised by the server during the last successful anonymous check.

Use this when someone has a list of wedding guests and wants them assigned to tables, keeping families, friend groups, or couples together and keeping specific people apart. Accepts names with optional group labels and keep-apart pairs. Returns table assignments and a shareable chart. Do not use for floor plans without names (use plan_reception_layout) or for RSVP tracking.

Use this when someone wants a minute-by-minute wedding day schedule: getting ready, first look, ceremony, cocktail hour, reception, send-off. Needs the ceremony start time; everything else has defaults. Do not use for the months-long planning checklist or vendor payment schedules.

estimate_wedding_budget — Wedding budget breakdown

Advertised by the server during the last successful anonymous check.

Use this when someone gives a total wedding budget, a guest count, or both and wants a category-by-category split (venue, catering, photo and video, flowers, music, attire, stationery, and so on) with per-guest math and a contingency line. Do not use for tracking actual spending or vendor payments.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http altessa-wedding-planner-mcp https://mcp.altessa.studio/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add altessa-wedding-planner-mcp --url https://mcp.altessa.studio/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable altessa-wedding-planner-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "altessa-wedding-planner-mcp": {
      "url": "https://mcp.altessa.studio/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).

Cline configuration

{
  "mcpServers": {
    "altessa-wedding-planner-mcp": {
      "type": "streamableHttp",
      "url": "https://mcp.altessa.studio/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start altessa-wedding-planner-mcp and inspect its tools.

VS Code configuration

{
  "servers": {
    "altessa-wedding-planner-mcp": {
      "type": "http",
      "url": "https://mcp.altessa.studio/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.

Gemini CLI configuration

gemini mcp add --transport http altessa-wedding-planner-mcp https://mcp.altessa.studio/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.
