Untap

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

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.
