"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.

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.

The company registry MCP: company data for AI agents, any country. One MCP server and REST API over national business registries — Norway (Brønnøysundregistrene / Enhetsregisteret, lookup by organisasjonsnummer/orgnr, VAT status) and the United Kingdom (Companies House, lookup by company number, accounts and confirmation-statement deadlines). Five tools: lookup_company, search_company, company_dea

Enables querying the Polish National Health Fund (NFZ) public API for medical waiting lists and service dictionary, allowing AI to compare wait times and find providers.

Provides Japanese business day calculations: add or subtract business days, count between dates, check whether a date is a business day, and reverse-calculate deadlines. Handles national holidays and year-end periods fully offline with no API keys required.

Provides Japanese national holidays, wareki (era) conversion, and date information. Works fully offline with no API keys required.

Default-deny action registry, append-only spend ledger, and human sign-off audit trail (MCP tools).

7M+ real estate transactions from Poland's RCN registry. Search, compare, and analyze prices

Agent Security & Hallucination Gate (x402)

Professional Proton Mail management with 20+ tools, advanced analytics, and seamless Proton Bridge integration.

Local MCP server for the Polish National Bank (NBP) public API enabling exchange rates, gold prices, and currency conversion without authentication.

MCP server for ENAHO (Peru's national household survey) microdata. Enables discovery, download, merging, and complex-survey statistical estimation of official poverty and income indicators, with report generation.

Read and write email through the Atomic Mail from an AI agent. Handles proof-of-work authentication and JMAP so the agent thinks in JMAP method calls. Use when the user asks to register an email inbox, list mailboxes, fetch or send email.

PII sanitization layer for autonomous AI agent pipelines. Detects and redacts emails, phone numbers, national IDs, private keys, and financial data before text reaches LLMs. Supports EN, ES (LATAM), PT (BR/PT), DE, JA.

Retrieve Mail from icloud

Enables read-only search and retrieval of your email across multiple IMAP accounts through a local notmuch index, served over authenticated HTTP for MCP clients like Claude or Codex.

Full-stack email MCP server in Rust: IMAP, SMTP, Exchange Web Services, and Microsoft Graph in one binary, with OAuth2 and multi-account support. Read, search, send, reply, forward, bulk operations, and attachment download to disk.

Deterministic AST vulnerability remediation and formal verification for AI coding assistants using Microsoft Z3 SMT logic.

A TypeScript MCP server that enables LLMs to send outbound emails via SMTP with support for attachments and HTML content. It includes outcome-oriented tools for account validation and enforces strict security policies like recipient allowlists and size limits.

Privacy-first, read-only repo intelligence for AI coding agents: scans local codebases and recommends MCP servers, repos, and research without sending data to the cloud.
