occasion_date — When is a holiday
Advertised by the server during the last successful anonymous check.

create_board — Create a group card
Advertised by the server during the last successful anonymous check.
Open-world

Creates a group greeting card that several people sign before it opens on a set date, and returns the link to send to participants. Requires the organiser's email: the full management links are sent there, and a one-time 'take control' link is returned. Ask the person for anything missing; never invent an email. For Дарим (darim.ai) names are Russian; for Yahad (yahad.ai) Hebrew.

gift_budget — Split a group gift
Advertised by the server during the last successful anonymous check.
Advertised read-only

How much each person gives toward a group gift: divide the cost by those who will actually pay, round down; the organiser adds the rest. Or, from a per-person amount, the total budget. Pass exactly one of giftCost or perPerson. Amounts are in the service's currency.

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 yahad-mcp https://api.yahad.ai/mcp

Codex

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