Price MCP server

Which servers in the official MCP registry are Price's own, 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 namewin.price/pricewinverified in the MCP registry

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

On 2026-10-21 the server answered initialize and tools/list without a sign-in. First answer in 601 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 4 of the 7 days it takes to judge reliability.

Once connected

  • Keep approval on for request_cancel_token: they delete, send or pay without saying so.
  • request_cancel_token, cancel_booking change data without a sign-in: anyone with the address can call them.

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.

What an agent can do with it

  • not sure · compare hotel prices across booking sites
  • not sure · compare flight fares on Vietnam routes
  • not sure · find the cheapest deal before booking

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 delete, send or pay without telling the client so: request_cancel_token
  • Tools that change data, on a server that answers without a sign-in: request_cancel_token, cancel_booking

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 (30%), doing the product's job (25%), definitions (20%), context (10%) and use (15%). 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 →

How to connect

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

{
  "mcpServers": {
    "pricewin": {
      "type": "http",
      "url": "https://mcp.price.win/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http price https://mcp.price.win/mcp

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://mcp.price.win/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.
