"National Rail" matching MCP servers:

UK rail freight compliance MCP server enabling checks on ORR licensing, ROGS safety certificates, RIR 2011 interoperability, TSI standards, RID dangerous goods, and Network Rail capacity access. It also prepares ORR inspection packs against the 14 Major Issues.

Budget, approval, and receipt layer that agents call when they buy on a human's behalf. MCP server with dry-run by default.

Policy-gated agent spend with signed receipts and rail-extract audit: a fail-closed gate issues a COSE receipt for every allowed payment, and the audit reconciles those receipts against a rail extract so a settlement with no receipt is named rather than assumed. It settles on a mock rail, holding no wallet and signing no transaction.

MCP server for the SOCseal sovereign rail — verify atomic SOC⇄BTC settlement proofs, read oracle/venue state, walk the no-KYC trade door. Live: socseal.xyz/proof

Provides MCP-callable workflow rails for agents, enabling bounded work execution, movement-fee quotes, payment authority references, paid rail runs, and signed receipts.

Enables evaluation of transaction geography, card BIN networks, authorization probabilities, and basis-point rail costs to select Pareto-optimal settlement paths across ACH, FedNow, and card rails. Returns the chosen rail, processing fee, effective fee percentage, and estimated savings versus standard card processing.

A machine-facing licensing and settlement rail for AI agent content access. search_pockets and list_pockets work with no key. pull_content needs a funded key and returns HTTP 402 with a registration URL when it has none. Every access, paid or refused, writes its own row with a receipt on both sides. $0.0025 default per pull, owners set their own. 85% to the creator.
