MCP tools · 17 exposed · ~2,487 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
award_allowances ~150

Allowances for an Australian modern award, from the Fair Work Commission MAPD. "kind"=wage (leading hand, first aid, tool) or expense (meal, travel, vehicle). By award code (e.g. "MA000009") or fixed id. Returns each allowance's amount, all-purpose flag and payment frequency, verbatim (CC BY 4.0). Dollar values only: does NOT determine which allowance applies — read with the award, which prevails. Not legal advice.

NameTypeReqDescription
awardstringyesModern award code (e.g. "MA000009") or numeric award_fixed_id.
kindstring–Which allowance register. Defaults to wage.

No output schema declared.

{"award":"MA000009","kind":"wage"}
award_pay_rate ~193

Minimum pay rates for an Australian modern award, from the Fair Work Commission MAPD. Input an award code (e.g. "MA000009") or fixed id, optionally filtered by classification level or employee-rate-type. Returns each classification's base and calculated rate with operative dates, verbatim from the FWC and stamped with version/published-year (CC BY 4.0). Dollar values only: does NOT say which award or classification applies, or what is payable — read with the award, which prevails. Not legal advice; unknown award throws.

NameTypeReqDescription
awardstringyesModern award code (e.g. "MA000009") or numeric award_fixed_id.
classificationLevelinteger–Narrow to one classification level (1 = lowest).
employeeRateTypestring–Filter by employee_rate_type_code, e.g. "AD" for adult. Comma-delimited for several.

No output schema declared.

{"award":"MA000009","classificationLevel":1}
award_penalties ~185

Penalty rates (weekend, public holiday, overtime, shift) for an Australian modern award, from the Fair Work Commission MAPD. By award code (e.g. "MA000009") or fixed id, optionally by classification level or employee-rate-type. Returns each penalty's multiplier/percentage and the FWC's own calculated dollar value, verbatim (CC BY 4.0). Dollar values only: does NOT determine which penalty applies to a shift — read with the award, which prevails. Not legal advice; unknown award throws.

NameTypeReqDescription
awardstringyesModern award code (e.g. "MA000009") or numeric award_fixed_id.
classificationLevelinteger–Narrow to one classification level.
employeeRateTypestring–Filter by employee_rate_type_code, e.g. "AD". Comma-delimited for several.

No output schema declared.

{"award":"MA000009"}
calculate_gst ~115

Add GST to a GST-exclusive amount, or extract the GST from a GST-inclusive amount, in exact integer cents. GST in an inclusive price is one ELEVENTH, not one tenth. "basis" is required — "exclusive" adds, "inclusive" extracts (synonyms accepted); an unknown basis throws rather than returning a wrong figure.

NameTypeReqDescription
amountstringyesThe money amount, e.g. "110.00". At most two decimal places.
basisstringyesWhether the amount already includes GST.

No output schema declared.

{"amount":"110.00","basis":"inclusive"}
check_ai_crawler_access ~122

FREE. Before fetching a URL, learn whether your crawler identity will be served, refused, or met by a paid tollgate (Cloudflare Pay Per Crawl, TollBit, a bare 402) — from a standing census, with the price where published and whether the site varies by user-agent. Unknown URLs return "unknown" and schedule themselves. Bulk: triage_ai_crawler_access. Observational (a datacenter vantage), not a guarantee.

NameTypeReqDescription
urlstringyesThe page whose crawler-access posture to look up. http or https.

No output schema declared.

{"url":"https://www.nytimes.com/"}
compare_entity_names ~166

Score whether two names are the same entity, 0 to 1, with the reasoning broken out. Knows 81 spellings of 30 legal forms across 21 countries ("Pty. Ltd." = "Proprietary Limited"), ignores word order ("Smith, John" = "John Smith"), and down-weights generic words (so "Woolworths Group" and "Coles Group" stay distinct). Flags obfuscation (homoglyphs, invisible characters, digit substitution) in an "obfuscation" field. Check "distinctiveness": names of only generic words identify weakly however well they match.

NameTypeReqDescription
astringyesFirst name.
bstringyesSecond name.
typestring–Defaults to company.

No output schema declared.

{"a":"ACME Pty Ltd","b":"Acme Proprietary Limited"}
deduplicate_entity_names ~104

Cluster up to 250 names into groups that are the same entity — the work behind a CRM merge or supplier-list cleanup. Grouped by distinctive words, not compared exhaustively; the response reports how many comparisons ran. If one word dominates the list, "truncated" is true (clustering incomplete) — split and retry.

NameTypeReqDescription
namesarrayyes–
thresholdnumber–Defaults to 0.85.
typestring––

No output schema declared.

{"names":["Acme Pty Ltd","ACME Proprietary Ltd","Beta Co"]}
match_entity_name ~125

Score one name against up to 750 candidates; returns those over the threshold, ranked, each tagged with its index in the input array. compare_entity_names applied as a search (legal-form-, word-order- and obfuscation-aware). Over 750 candidates throws rather than truncating.

NameTypeReqDescription
candidatesarrayyesNames to search.
limitinteger–Defaults to 10.
querystringyesThe name to look for.
thresholdnumber–Minimum score to return. Defaults to 0.7.
typestring––

No output schema declared.

{"candidates":["ACME Pty Ltd","Beta Co","Acme Corporation"],"query":"Acme"}
normalise_entity_name ~89

Reduce a name to its comparable core with the legal form split out — a stable, deterministic grouping key. Reports every token removed and flags any obfuscation it strips (homoglyphs, invisible characters, digit-for-letter substitution). The normalisation the matching tools apply, exposed on its own.

NameTypeReqDescription
namestringyesThe name to normalise.
typestring––

No output schema declared.

{"name":"ACME Pty. Ltd."}
pull_ai_crawler_watch ~88

Given a watchId from watch_ai_crawler_access, returns the URLs whose access changed since your last pull (started refusing, a tollgate appeared, a price moved) and nothing for those unchanged. The first pull reports the starting state. Each pull spends one credit whether or not anything changed.

NameTypeReqDescription
watchIdstringyesThe watchId returned by watch_ai_crawler_access.

No output schema declared.

{"watchId":"a4177d3f-b6bb-4bcb-a691-50949dd95f41"}
superannuation_guarantee ~190

Compute the Australian Superannuation Guarantee on a qualifying-earnings amount, exact to the cent. Returns the SG, the rate, the earnings subject to SG after the annual maximum-contributions-base cap, and the financial year used. Computed the CURRENT way — from 1 July 2026 the base is qualifying earnings (not OTE) and the cap is annual, under Payday Super, so old quarterly-OTE code is now wrong. You supply the qualifying-earnings figure; this does NOT define what counts as qualifying earnings. ATO-sourced, not tax advice. Current financial year only; an out-of-range date throws.

NameTypeReqDescription
asAtstring–YYYY-MM-DD — which schedule to use. Defaults to today.
qualifyingEarningsstringyesThe qualifying-earnings amount to compute SG on, e.g. "5000.00".

No output schema declared.

{"qualifyingEarnings":"5000.00"}
total_invoice ~99

Total a multi-line invoice in integer cents, handling GST-free lines and both ATO rounding methods (per-line and total-based), and report the exact discrepancy between them — an invoice must not mix them. A malformed line throws.

NameTypeReqDescription
linesarrayyesInvoice lines.
roundingstring–Round GST per line, or once over the total. Defaults to line.
taxInclusiveboolean–Whether unitPrice values already include GST.

No output schema declared.

{"lines":[{"description":"Consulting","quantity":2,"unitPrice":"100.00"},{"description":"Milk","gstFree":true,"unitPrice":"5.00"}],"taxInclusive":false}
triage_ai_crawler_access ~117

Check up to 200 URLs in one call for AI-crawler access — which your identity can read, which refuse it, and which sit behind a paid tollgate — with a summary to branch on before spending a fetch. Unknown URLs cost nothing and schedule themselves; known URLs are metered. Observational (what a datacenter vantage saw), not a guarantee; a user-agent is a claim, not a credential.

NameTypeReqDescription
urlsarrayyesThe URLs to triage. Up to 200. http or https.

No output schema declared.

{"urls":["https://www.nytimes.com/","https://www.reddit.com/"]}
validate_australian_identifier ~135

Validate an Australian ABN, ACN, ARBN, TFN, Medicare or BSB against its official checksum. Offline and deterministic; whitespace and hyphens ignored; a valid ABN also flags whether the holder is a company. A pass proves the digits are internally consistent (catches typos and fabrications); it does NOT prove the identifier is issued, active, or held by anyone. BSB has no check digit: format only. Unknown scheme throws.

NameTypeReqDescription
typestringyesWhich identifier scheme to check.
valuestringyesThe identifier. Spaces and hyphens are ignored.

No output schema declared.

{"type":"abn","value":"51 824 753 556"}
verify_ai_crawler ~324

FREE. Is a crawler who it claims to be, by the strongest available method. CRYPTOGRAPHIC (best): pass a Web Bot Auth signature (RFC 9421) with its signatureInput, signatureAgent and url — we fetch the operator's published key and verify it (proof of key control, not just network origin). NETWORK: pass a source ip with userAgent/claimed — we check the operator's published IP ranges (OpenAI, Anthropic, Google, Perplexity, Bing, Apple, DuckDuckGo, Common Crawl, Mistral, Kagi, and more). Returns verified, spoofed, unrecognised, or indeterminate; never calls a claim spoofed when it merely cannot be checked.

NameTypeReqDescription
claimedstring–Optional explicit identity key (e.g. "gptbot", "bingbot", "googlebot") instead of a user-agent.
ipstring–The source IP address to verify (IPv4 or IPv6). Used for the network-range check.
signaturestring–The request's Signature header value (Web Bot Auth / RFC 9421).
signatureAgentstring–The request's Signature-Agent header value — the operator key-directory URL.
signatureInputstring–The request's Signature-Input header value.
urlstring–The request URL — required for a Web Bot Auth signature check (rebuilds the signed components).
userAgentstring–The User-Agent string the request presented. Used to infer the claimed identity.

No output schema declared.

{"ip":"203.0.113.10","userAgent":"Mozilla/5.0 (compatible; GPTBot/1.1; +https://openai.com/gptbot)"}
verify_email_address ~149

FREE. Validate an email before spending a send, token, or signup — no mail sent, no SMTP probe. Checks RFC-5322 syntax, live MX over DNS (and names the provider), disposable domains, role mailboxes (info@ — custom domains only, never freemail), and typos (gmial.com to gmail.com). Returns one verdict (deliverable, undeliverable, disposable, role_address, typo_suspected, or invalid), a 0-100 deliverability score, the canonical mailbox for dedup, and a verdict hash. Confirms domain reachability, not that a specific mailbox exists.

NameTypeReqDescription
emailstringyesThe email address to check.

No output schema declared.

{"email":"name@example.com"}
watch_ai_crawler_access ~136

Register a set of URLs and pre-buy pull credits; the census watches them for access changes — a paywall appearing, an identity refused, a tollgate. Returns a watchId (bearer token — keep it secret). Pull changes with pull_ai_crawler_watch. Adds are free, pulls are paid; a watch expires after inactivity.

NameTypeReqDescription
creditsinteger–How many pulls to buy. Defaults to 10.
freshnessstring–Whether this set is checked ahead of the general census. Same price; defaults to standard.
urlsarrayyesThe URLs to watch. Up to 200.

No output schema declared.
