## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-08-03.

- **Endpoint Security**: 57/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 5 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 59/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 2246 tokens (~449/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 13/100
  - Stability observed for 4 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (5)

### `company_lookup` (~345 tokens)

Look up a Brazilian company in the official government registry by CNPJ or company name.

Returns the full registration record from the Receita Federal (Brazil's federal tax authority) CNPJ database: registration status (active, suspended, closed), legal name (razão social), trade name (nome fantasia), head office or branch, opening date, legal nature, company size, share capital, main and secondary economic activities (CNAE codes with descriptions), full address with IBGE city code, tax regime (Simples Nacional / MEI), and the partners and shareholders board (QSA) as registered.

Input: a CNPJ — the 14-digit Brazilian company tax ID, punctuation optional — or a company name, resolved via full-text search over legal and trade names. A CNPJ that does not exist returns result_status "not_found". Useful for KYB (know your business), due diligence, supplier and vendor verification, credit analysis, B2B prospecting, and compliance checks on companies in Brazil. Registry data is refreshed monthly from official open data; the response carries its source reference date.

The response also carries has_corporate_group: true when the company has corporate (PJ) shareholders or subsidiaries, i.e. when company_group would return an actual graph. Use this cheap call to qualify before spending on the more expensive one — only ~0.7% of Brazilian companies have a corporate shareholder (27-39% among those with share capital above R$ 1M). Null means the ownership graph is not loaded, never assume false.

Input parameters:

- `query` (string, required): A CNPJ (14-digit Brazilian company tax ID, punctuation optional) or a company name

### `company_sanctions` (~228 tokens)

Screen a Brazilian company for sanctions and debarment by CNPJ (the 14-digit Brazilian company tax ID, punctuation optional).

One call checks 5 federal sanction lists: CEIS (companies debarred from public contracting), CNEP (penalties under the anti-corruption law), CEPIM (non-profits barred from federal agreements), Acordos de Leniência (leniency agreements with enforcement status) and the MTE forced-labor employers register ("Lista Suja" do trabalho escravo). Returns each matching entry with list, sanction type, sanctioning body and validity dates, plus an is_currently_sanctioned verdict, the lists checked and any list that was unavailable — sources and reference dates declared.

The Brazilian complement that global OFAC/EU/UK/UN and PEP screens miss. Useful for KYB (know your business), AML/compliance screening, supplier and vendor onboarding, procurement eligibility checks and counterparty risk on companies in Brazil.

Input parameters:

- `query` (string, required): A CNPJ (14-digit Brazilian company tax ID, punctuation optional)

### `company_group` (~271 tokens)

Map the corporate group (economic group) of a Brazilian company by CNPJ (the 14-digit Brazilian company tax ID, punctuation optional).

Answers what a standard registry lookup cannot: not just who the corporate shareholders of this company are, but its subsidiaries (the companies it holds), the parent companies above those shareholders, the sibling companies under the same parent, and the ultimate parent at the top of the ownership chain. Returns exact counts plus the nodes themselves — each with legal name, registration status, company size and state — so no follow-up lookups are needed. Consortium relationships ("Sociedade Consorciada", an alliance for a single contract) are reported separately and never counted as control.

Built from the Receita Federal partner registry (QSA), rebuilt monthly. Company-to-company shareholding only: natural-person partners are never used to link companies and never appear in the response. Ownership percentages are not published by the source. Useful for KYB (know your business), AML and sanctions exposure through affiliates, counterparty and concentration risk, M&A research and supplier due diligence in Brazil. Companies with no corporate shareholder return result_status "no_group" — common for micro companies, expected for mid-size and large ones.

Input parameters:

- `query` (string, required): A CNPJ (14-digit Brazilian company tax ID, punctuation optional)

### `company_debts` (~288 tokens)

Check a Brazilian company for federal tax debt by CNPJ (the 14-digit Brazilian company tax ID, punctuation optional).

Returns the company's registered federal debt (Dívida Ativa da União) as published quarterly by the PGFN, Brazil's federal treasury attorney general: number of inscriptions, consolidated amount in BRL, how many are under judicial enforcement, how many are in installment plans or renegotiated, the oldest and newest inscription dates, and a breakdown by type — non-social-security, social security contributions and FGTS (severance fund). Debt is aggregated across every establishment of the company, so querying a branch still surfaces debt registered against headquarters.

Tax delinquency is the first question in Brazilian due diligence and is not part of the company registry: it is a separate federal dataset. Useful for KYB, credit and counterparty risk, supplier onboarding and financial health checks. Consolidated amounts are the registered stock and include suspended, renegotiated and installment-plan inscriptions — the response carries counters and a disclaimer so the number is never read as immediately enforceable debt. Federal scope only: state (ICMS) and municipal (ISS) debts are not covered. A CNPJ with no debt returns result_status "no_debt"; one absent from the registry returns "not_found".

Input parameters:

- `query` (string, required): A CNPJ (14-digit Brazilian company tax ID, punctuation optional)

### `company_dossier` (~267 tokens)

Build an aggregated due-diligence dossier on a Brazilian company by CNPJ (the 14-digit Brazilian company tax ID, punctuation optional).

One call aggregates multiple official government sources into a single structured report: full registry record from Receita Federal (status, legal name, activities, address, partners/QSA); public procurement contracts from PNCP (Brazil's national procurement portal); the corporate group ownership graph (company-to-company shareholders and subsidiaries); registered federal tax debt from the PGFN Dívida Ativa da União, including social security and FGTS, aggregated across every establishment of the company; sanctions screening across 5 federal lists (CEIS, CNEP, CEPIM, leniency agreements and the MTE forced-labor register); and derived compliance risk flags (inactive company, active sanction, federal tax debt, recently opened). Sections are independent and degrade gracefully: if a source is down its section is marked unavailable, never a total error.

Replaces an analyst-hour of manual checks across Brazilian government portals. Useful for KYB (know your business), vendor and supplier due diligence, counterparty risk, credit analysis, AML/compliance screening, and M&A research on companies in Brazil.

Input parameters:

- `query` (string, required): A CNPJ (14-digit Brazilian company tax ID, punctuation optional)
