Server-provided instructions

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

Zovo Sign-Up Sheet publishes a sheet of slots (potluck dishes, volunteer shifts, carpool seats) that people claim in any browser. Each slot has a capacity, and a full slot cannot be taken. create_signup_sheet returns a public link to share and a private organizer link. show_signup_results reads who took what and which slots are open. update_signup_sheet adds, changes or removes slots and closes or reopens the sheet.

create_signup_sheet — Create sign-up sheet
Advertised by the server during the last successful anonymous check.
Open-world

Use this when the user wants people to claim slots: potluck dishes, volunteer shifts, carpool seats, snack turns. It publishes a shared page where each person enters a first name and picks slots; each slot has a capacity and a full slot cannot be taken. Returns a public link to share and a private organizer link. Slots may have dates and times (then give an IANA time_zone). Does not send emails or reminders and does not take payments.

Use this when the user asks who signed up, what is still open, or how many spots are left on a sheet made with create_signup_sheet. Takes the private organizer link and returns each slot with its capacity, spots taken, open spots and names, plus people's notes. Does not work with the public link and does not change the sheet.

update_signup_sheet — Update sign-up sheet
Advertised by the server during the last successful anonymous check.
Open-world

Use this when the organizer wants to change a sheet made with create_signup_sheet: add slots, change a slot's label or capacity, remove an empty slot, change the per-person limit, show or hide names, edit the note, or close and reopen sign-ups. Takes the organizer link and only the changes. A capacity cannot go below the people already signed up, and a slot with sign-ups cannot be removed. Does not notify participants.

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 zovo-sign-up-sheet-mcp https://signup-sheet.zovo.one/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 zovo-sign-up-sheet-mcp --url https://signup-sheet.zovo.one/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable zovo-sign-up-sheet-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "zovo-sign-up-sheet-mcp": {
      "url": "https://signup-sheet.zovo.one/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "zovo-sign-up-sheet-mcp": {
      "type": "streamableHttp",
      "url": "https://signup-sheet.zovo.one/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start zovo-sign-up-sheet-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "zovo-sign-up-sheet-mcp": {
      "type": "http",
      "url": "https://signup-sheet.zovo.one/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 zovo-sign-up-sheet-mcp https://signup-sheet.zovo.one/mcp

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.
Claude Desktop configuration
https://signup-sheet.zovo.one/mcp

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
{
  "mcpServers": {
    "zovo-sign-up-sheet-mcp": {
      "serverUrl": "https://signup-sheet.zovo.one/mcp"
    }
