Schema Quality & AI Usability70
  • AI-judged instruction clarity (good).Pass
  • Context-footprint check failed: tool/resource definitions use about 659 tokens (~164/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail

MCP tools · 4 exposed · ~562 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
compute_codice_fiscale ~215

Compute the Italian codice fiscale (tax code) of a person from surname, name, sex, birth date and birth place, with the D.M. 23/12/1976 rules. The place can be a comune ('Roma', 'Castro (LE)'), a foreign state ('Francia') or a codice catastale ('H501'); the code valid on the birth date is used. Returns the 16 characters and why each group has its value. The Agenzia delle Entrate may assign an omocodic variant: only it confirms a code.

NameTypeReqDescription
birth_datestringyesBirth date, YYYY-MM-DD (DD/MM/YYYY accepted).
birth_placestringyesComune (with province if ambiguous), foreign state, or codice catastale / Z-code.
namestringyesGiven name(s) (nome), all of them.
sexstringyesM or F.
surnamestringyesSurname (cognome), as on the document.

No output schema declared.

No examples provided.

decode_codice_fiscale ~97

Read back a codice fiscale: sex, birth date (one or two possible centuries), birth comune or foreign state valid on that date, the consonant codes of surname and name, and omocodia. The full name cannot be recovered from a code. Fails with the reason when the format or the check character is wrong.

NameTypeReqDescription
codestringyesCodice fiscale, 16 characters (spaces and lowercase accepted).

No output schema declared.

No examples provided.

lookup_place ~119

Search the 15,000 comuni of every era and the foreign states of the ANPR archive by name or by code (codice catastale like H501, Z-code like Z110). Returns up to 20 places with their province and the dates their code was valid. Give a date to keep only the places valid on it.

NameTypeReqDescription
datestring–Optional date YYYY-MM-DD: only places valid on that day.
qstringyesName ('Roma', 'Sant Angelo') or code ('H501', 'Z110').

No output schema declared.

No examples provided.

verify_codice_fiscale ~131

Check that a codice fiscale is well formed, layer by layer: format, check character, a real birth date, a place code valid on that date, and optionally the surname and name letters. It says whether the code is written correctly, not whether the Agenzia delle Entrate has assigned it (only its own service does).

NameTypeReqDescription
codestringyesCodice fiscale, 16 characters (spaces and lowercase accepted).
namestring–Optional name to match against characters 4-6.
surnamestring–Optional surname to match against characters 1-3.

No output schema declared.

No examples provided.
