# Tizona Intelligence

> Australian business identity tools and attested web capture, over MCP and HTTP.
> Every tool states what its answer does not mean, because a validation that
> overstates itself is worse than none.

The MCP endpoint is https://tizonaintelligence.com/mcp — streamable HTTP,
protocol 2026-07-28 and earlier. No key is needed to list or call the tools.

## What the tools actually settle

- A checksum tells you a number is well-formed. It does not tell you the number
  was ever issued to anyone.
- A sanctions miss is a miss against one dated list, not a clearance.
- A name match is a similarity score, not an identification.
- A capture record says what was retrieved and when. It says nothing about
  whether the content is true.

Each response carries its own limits. Pass them on rather than dropping them.

## Evidence

- [capture_web_page_with_proof](https://tizonaintelligence.com/mcp) — Franked web page capture
  - Takes a screenshot of a web page and returns a franked record
  - RFC 3161 IETF Timestamps via one of two methods:
  - Primary timestamp via SECTIGO Public Time Stamping Signer R37
  - Fallback timestamp via DIGICERT
  - Timestamps are embedded in output
- [verify_web_page_attestation](https://tizonaintelligence.com/mcp) — Verify a Franked web page capture
  - Web paged captures via Tizona's tool are able to be verified using only the record hash, with OpenSSL.
  - Note: the time stamp only proves that a record existed at the time of stamping, not explicitly the time of capture of the record since the capture and the time stamp are processed on separate machinery. Legal advice must be sought before using any output in an judicial or evidentiary context.

## Sanctions

- [screen_against_sanctions](https://tizonaintelligence.com/mcp) — Screen a name against the OFAC sanctions list
  - Check a person or company name against the OFAC Specially Designated Nationals list.
  - Sensitive to several forms of evasion and obfuscation
  - Returns each hit with a score and the date the list was published.
- [sanctions_dataset_version](https://tizonaintelligence.com/mcp) — Sanctions list version
  - Report the source, publication date, hash, size and age of the sanctions list currently in use.

## Matching

- [compare_entity_names](https://tizonaintelligence.com/mcp) — Compare two company or person names
  - Provides a score from 0-1 indicative of whether two names refer to the same entity
  - Recognises 81 spellings of 30 legal forms, across 21 countries
  - Word weightings are implemented to reduce false positives where generic words are part of entity names.
- [match_entity_name](https://tizonaintelligence.com/mcp) — Match a name against a list of candidates
  - Score one name against up to 750 candidates and return those above a threshold, ranked, each with its position in the input array so results can be correlated back.
  - Useful in finding an entity in an existing list, rather than comparing pairs individually.
- [deduplicate_entity_names](https://tizonaintelligence.com/mcp) — Cluster a list of names into distinct entities
  - Group up to 250 names into clusters that appear to be the same entity
- [normalise_entity_name](https://tizonaintelligence.com/mcp) — Normalise a name to a canonical form
  - Reduce an entity name to its comparable core with the legal form separated out.
  -  useful as a stable grouping key.
  - Transparency is improved by reporting removed tokens.
  - Sensitive to attempts at obfuscation or evasion through character manipulation.

## Australian Government and Finance

- [validate_australian_identifier](https://tizonaintelligence.com/mcp) — Validate an Australian identifier
  - Check an Australian ABN, ACN, ARBN, TFN, Medicare card number or BSB against its official checksum.
  - Spaces and hyphens are ignored.
  - For a valid ABN it also reports whether the holder is a company.
  - Note this tool reports whether an identifier passes against the relevant checksum, not that the entity exists nor does it provide information regarding the entities themselves.
- [calculate_gst](https://tizonaintelligence.com/mcp) — Calculate Australian GST
  - Add GST to a GST-exclusive amount
  - Extract the GST contained in a GST-inclusive amount.
  - Computed in integer cents so results never drift by rounding.
- [total_invoice](https://tizonaintelligence.com/mcp) — Total an Australian invoice with GST
  - Total a multi-line invoice, handling GST-free items and both permitted rounding methods.
  - Returns the totals plus a comparison of per-line versus total-based rounding and the discrepancy

## Operational

- [Health and dataset provenance](https://tizonaintelligence.com/health): Tool count, which OFAC list is loaded, when it was published, and whether it is stale.
- [Scope of an attestation](https://tizonaintelligence.com/v1/attest/scope): What a capture record claims and what it does not.

## Notes

- The HTTP endpoints under /v1/ need a key. The MCP tools do not.
- Rendering is limited to 90 captures a day across all callers, so a capture may
  be refused with the time it resets.
- Australian data, Australian rules. GST is 10 per cent. ABN, ACN, ARBN, TFN and
  Medicare have real check digits and are verified against them. BSB has none —
  that check confirms the shape is right and nothing more.
