PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

Before you install

  • Basic checks: 1 of 1 passed

Common questions

Is Untap safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.3.3) reached the registry 27 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Untap for AI assistants

Check whether you are owed money for a delayed train, a disrupted flight, a TfL overcharge or a UK parking ticket, and get the operator's own claim link.

Untap checks UK refunds and compensation from delayed trains, disrupted flights, TfL journey charges and parking notices. Public checks return the applicable rules, amount, deadline and claim guidance. Sign in to save claims, track progress and check saved train commutes for dates you request. You submit claims directly to the operator or airline. Untap never files a claim for you.

Every package here is a thin wrapper around the same hosted MCP server, plus Untap's skills:

https://untap.money/api/mcp

Tools live on the server, so they update in every assistant without a new package. Version 1.3.4.

Install

Claude Code

/plugin marketplace add aneduaim/untap-mcp

/plugin install untap@untap

Claude (web, desktop and Cowork): go to Customize, Plugins, Add, Add marketplace and paste https://github.com/aneduaim/untap-mcp. Install Untap, then connect it from the plugin's Connectors tab. You can also add https://untap.money/api/mcp as a custom connector.

ChatGPT and Codex: plugins/agent-plugins is an Agent Plugins 1.0.0 package, and .agents/plugins/marketplace.json lists it as a repo marketplace. In ChatGPT developer mode you can also add https://untap.money/api/mcp as a connector.

Cursor and Grok Bot: plugins/cursor is the Cursor plugin package, listed in .cursor-plugin/marketplace.json. You can also add https://untap.money/api/mcp in Cursor's MCP settings.

Gemini CLI: this repository is a Gemini CLI extension (gemini-extension.json and GEMINI.md at the root).

gemini extensions install https://github.com/aneduaim/untap-mcp

Account tools sign in with /mcp auth untap.

Any other MCP client: connect to https://untap.money/api/mcp over Streamable HTTP. Account tools sign you in through OAuth 2.1 with dynamic client registration; there are no API keys.

Setup guides for each assistant: untap.money/connect.

This table was generated from the server's source for version 1.3.4. The live list is always the server's own tools/list at https://untap.money/api/mcp. 7 of 20 tools work without signing in.

Skills

  • uk-travel-claims: Checks UK travel compensation and refunds with Untap: Delay Repay for late or cancelled trains, UK261 or EU261 flight delays, cancellations, denied boarding, TfL incomplete journeys, maximum fares.
  • find-travel-refunds-in-inbox: Searches an inbox for UK train, flight and TfL refunds the person may be owed, then checks them with Untap. Use for find refunds, money I'm owed, check my emails for compensation, travel refunds.

The same skills can be downloaded on their own at untap.money/skills.

Privacy

When your assistant calls an Untap tool, Untap receives the inputs the assistant sends to that tool. It does not receive your conversation or other chats.

  • Check tools work without signing in. They do not save your booking or result to an account. To verify a journey, Untap sends the stations, airports, flight number and date to National Rail or its flight-data provider. Technical usage records (tool name, outcome, duration) are kept; anonymous records contain no tool inputs.
  • If you sign in and ask your assistant to save a claim, journey or commute, Untap stores those details in your account until you delete them. A saved commute is checked only when you ask.
  • Revoke an assistant at untap.money/settings/connections. Delete your data at untap.money/data or with the two-step delete tool.

Full details: privacy policy.
