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 →
cnmv_annual_reports ~213
List a Spanish issuer's annual financial reports (Informes financieros anuales) from the CNMV official register: financial-year end, CNMV publication date, auditor, audit opinion, and links to the individual and consolidated reports and to the ESEF report package (ZIP/.xbri containing the iXBRL report and taxonomy files). Identify the issuer by nif, isin or company name. Covers every year the issuer has filed (back to the 2000s for long-listed issuers); ESEF packages exist from FY2020 onward.
| Name | Type | Req | Description |
|---|---|---|---|
| company | string | – | Issuer name, e.g. "Tecnicas Reunidas". |
| isin | string | – | Issuer share ISIN, e.g. "ES0178165017". |
| limit | number|string | – | Most recent N financial years to return (1-40). Default 5. |
| nif | string | – | Issuer NIF as CNMV records it, e.g. "A-28092583". |
No output schema declared.
No examples provided.
cnmv_find_issuer ~121
Resolve a Spanish-market issuer name or ISIN to the NIF the CNMV registers use, via the CNMV entity search and ISIN register. Returns the matching entities (name + NIF) and the CNMV entity page URL. Use the NIF with cnmv_search_filings or cnmv_annual_reports.
| Name | Type | Req | Description |
|---|---|---|---|
| company | string | – | Entity name or fragment, e.g. "Tecnicas Reunidas", "Santander". |
| isin | string | – | Security ISIN, e.g. "ES0178165017". |
No output schema declared.
No examples provided.
cnmv_search_filings ~464
Search Spanish listed-company regulated disclosures filed with the CNMV (Comisión Nacional del Mercado de Valores), the Spanish securities regulator: "Otra información relevante" (results, annual and half-year financial report notices, buybacks, governance, liquidity contracts) and "Información privilegiada" (inside information). PREFER OVER esef_filing_search FOR SPANISH ISSUERS — CNMV publishes within minutes of registration, while the community ESEF index runs months behind for Spain. Filter by date window (date_from/date_to, inclusive, default last 7 days), and optionally one issuer by nif, isin or company name. Returns disclosure EVENTS — company, NIF, category, title, Madrid-time publication timestamp, registration number and document URL — NOT extracted XBRL facts. For an issuer's annual financial reports with their ESEF ZIP download, use cnmv_annual_reports.
| Name | Type | Req | Description |
|---|---|---|---|
| company | string | – | Issuer name, e.g. "Tecnicas Reunidas", "Banco Santander". Resolved to a NIF with the CNMV entity search; when several entities match, the closest name is used and the others are listed under issuer_c… |
| date_from | string | – | First publication day to include (YYYY-MM-DD, Madrid calendar day, inclusive). Default: 7 days before date_to. |
| date_to | string | – | Last publication day to include (YYYY-MM-DD, inclusive). Default: today. |
| feed | string | – | "oir" = Otra información relevante, "ip" = Información privilegiada, "all" (default) = both, merged newest first. |
| isin | string | – | Issuer share ISIN, e.g. "ES0178165017". Resolved to the issuer NIF through the CNMV ISIN register first. |
| limit | number|string | – | Rows to return, newest first (1-50). Default 20. To go further back, narrow the date window rather than paging. |
| nif | string | – | Issuer Spanish tax id (NIF/CIF) as CNMV records it, e.g. "A-28092583" (Técnicas Reunidas). Most precise issuer filter. Get it from cnmv_find_issuer. |
