Summary
Connects Claude or ChatGPT to Untap's UK consumer refund engine via OAuth 2.1. Exposes six tools: add train journeys for Delay Repay checks against National Rail HSP, add flights for UK261/EU261 compensation lookups via AeroDataBox, add TfL contactless batches to detect overcharges and missed Hopper fares, add parking fines for appeal-ground analysis, list all claimable refunds, and delete user data. Each verdict includes a deeplink to the operator's claim form. Reach for this if you're in the UK and want your assistant to spot money you're owed from delayed trains, disrupted flights, botched Oyster taps, or dodgy parking tickets without surrendering bank credentials.

Untap MCP server
Connect Untap to your AI assistant. Untap is a UK consumer fintech that detects refunds you are already owed: train Delay Repay, UK261/EU261 flight compensation, TfL contactless overcharges, and parking-ticket appeal grounds.
This repo holds the directory metadata for the Untap MCP server. The server itself is hosted at:
https://untap.money/api/mcp
Install
See untap.money/connect for one-click install instructions for Claude (web and desktop), ChatGPT, and other MCP-compatible clients.
In short:
- Claude: open the add-connector dialog, paste the URL above, complete the Google sign-in.
- ChatGPT: Settings → Connectors → enable Developer Mode → add a custom MCP connector with the URL above.
Authentication
OAuth 2.1 with Dynamic Client Registration. End-users sign in with the Google account they use on Untap. No API keys to copy or manage.
Tools
Six tools, scoped to the four recurring UK refund categories:
| Tool | What it does |
|---|---|
add_train_journey | Add a UK train booking. Untap auto-checks National Rail HSP records and returns the Delay Repay verdict. |
add_flight | Add a flight. Untap auto-checks AeroDataBox and returns the UK261/EU261 verdict. |
add_tfl_journeys | Add a batch of TfL contactless journeys. Untap detects max-fare overcharges, incomplete journeys, and missed Hopper fares. |
add_parking_fine | Add a UK PCN. Untap runs the appeal-grounds engine and suggests the strongest grounds. |
list_savings | Read claimable / pending / historic refund opportunities. |
delete_my_data | Two-step destructive tool to wipe every booking and statement from the user's account. |
Untap never files claims itself. Every claimable verdict carries a
claim_url deeplink to the operator's site for the user to confirm and
submit.
Privacy
The MCP server cannot see passwords, payment details, or bank information. Per-tool rate limits, per-user audit log, and per-(user, client) revoke from untap.money/settings/connections.

The MCP server source is in the main Untap repository (private). This repo is the public directory metadata only.
