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

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