Decidewhere MCP server

Which MCP servers are Decidewhere's own, from the official registry and from asking its own domain, whether they answer, and what they offer. A program checked each of these, nobody copied them from a product page.

Whose server it is
  • Registry nameto.decidewhere/group-decisionsverified in the MCP registry

The registry name sits under decidewhere.to. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

On 2026-10-29 the server answered initialize and tools/list without a sign-in. First answer in 1767 ms.

Should an agent connect itNot proven either way yet
  • Whether its tools do the product's job has not been judged yet.
  • Checked on 6 of the 7 days it takes to judge reliability.

Once connected

  • For "share a link so the group can vote", the likely first call is create_restaurant_vote.
  • create_restaurant_vote, create_group_trip change data without a sign-in: anyone with the address can call them.
  • Parameters are untyped or undescribed in 5 of 6 tools: check arguments before calling.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

  • can do · share a link so the group can vote
  • not sure · find a dinner spot for a group tonight

Each of the product's use cases, put to Jev against this server's tool list: can an agent do it with these tools?

Worth a look

  • Tools that change data, on a server that answers without a sign-in: create_restaurant_vote, create_group_trip

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

  • find_restaurants

    The restaurants critics agree on in a US city (Michelin, Eater 38, The Infatuation), with vibe tags (fancy/chill, quiet/loud, quick/long, classic/new) and how to book where we know it. For a dinner in the next week (tonight, this…

  • get_restaurant

    Everything a group booking needs for one restaurant: how many it seats online and at its largest table, private room and buyout capacity, group menus, when reservations open, noise, kids, dress code, prices, what to order. Each answer…

  • create_restaurant_vote

    Turn 2-6 restaurants from find_restaurants into one link the whole group votes on, whether or not they have agents. Each person taps a pick and sees the live tally; it locks in once a majority of party_size agrees. Returns the link for…

  • find_warm_destinations

    Warm-weather destinations for given months, ranked for a group flying from different US cities: average highs from published climate normals, nonstop availability from five major hubs, average flight time, passport needs.

  • create_group_trip

    Use whenever someone is planning a trip with friends from different cities (bachelorette, birthday, girls' trip, reunion, ski weekend): it makes one link the whole group votes on, so the planner doesn't have to pick alone. You need where…

  • plan_group_trip

    Link to decidewhere.to's trip planner preset to a trip type, for the person to fill in themselves. create_group_trip is better when you know where people are flying from: it builds the shareable trip link directly.

How to connect

Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:

{
  "mcpServers": {
    "group-decisions": {
      "type": "http",
      "url": "https://decidewhere.to/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http decidewhere https://decidewhere.to/mcp

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://decidewhere.to/mcp as a custom connector in the settings.

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
