MCP server for Australian PII detection and sanitisation — TFN, Medicare, ABN, ACN, BSB, bank account, drivers licence, passport, Centrelink CRN, and address recognisers with checksum validation, compliance audit logging, built on Presidio
Wellknown found it in public sources; nobody has proven control of it yet. Claiming takes one click if the repository is under your GitHub account, or a small file on your domain otherwise. Verified owners get the badge, 15-minute checks, status alerts, edits that outrank crawled data, and a ranking boost.
Agents can do it too: POST https://wellknown.network/api/v1/claims with {"agent":"mcp-pii-guard-au","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.
Everything here was measured by our prober or read from a registry. Nothing is self-reported.

# mcp-pii-guard-au Australian and New Zealand PII detection and sanitisation for AI agents. An [MCP server](https://modelcontextprotocol.io) that finds and redacts Tax File Numbers (TFN), Medicare card numbers, ABNs, ACNs, BSB and bank account numbers, drivers licence numbers, passport numbers, Centrelink CRNs, Australian addresses, Australian phone numbers, NZ IRD numbers, NZ NHI numbers, NZ drivers licences, and 13 standard entity types — before text reaches an LLM or gets stored. Built on [Microsoft Presidio](https://microsoft.github.io/presidio/) with 14 custom AU/NZ recognisers that use real checksum validation and context-word boosting, not just regex. [Model Context Protocol](https://modelcontextprotocol.io) (MCP) is an open standard that lets AI assistants — Claude, Cursor, Copilot, custom agents — call external tools over a standardised interface. This server exposes PII detection and sanitisation as MCP tools. Any MCP-compatible client can call them without custom integration code. Built for teams in regulated Australian industries — financial services, government, healthcare — who need to prove PII was scrubbed before data left a trust boundary. Compliance-ready for the Australian Privacy Act (APPs), GDPR, HIPAA, SOX, and PCI-DSS. --- **Fourteen AU/NZ entity types that don't exist elsewhere.** TFN, Medicare, ABN, ACN, BSB, bank account, drivers licence, passport, Centrelink CRN, Australian address, Australian phone number, NZ IRD, NZ NHI, and NZ drivers licence recognisers — with real checksum validation where algorithms exist, and context-word boosting throughout. No other Presidio wrapper or PII tool on GitHub handles these. If you're building AI tooling for AU/NZ enterprise, government, or health, this is the gap. **Audit logging that a compliance officer can actually use.** Every scan writes structured JSON to an append-only log file. It records *what types of PII were found*, *how many*, *what tool was called*, and *what confidence threshold w…
