Calculadoras financeiras e dados econômicos do Brasil. 114 tools: salário líquido, rescisão, férias, 13º, FGTS, financiamento, DARF de ações e FIIs, Fator R, pró-labore ótimo, Tesouro Selic com custódia B3, LCI/LCA, CDI, juros compostos, backtest com série histórica oficial desde 2000, e mais. Dados vivos: Selic, CDI, IPCA, IGP-M, INPC, TR, dólar, poupança e salário mínimo do Banco Central; taxas de todos os títulos do Tesouro Direto; projeções do Boletim Focus; tabelas de INSS e IRPF com linha do tempo de vigência desde 2006; salários por profissão e custo de vida em 15 cidades. Cada número vem com a norma que o sustenta e a data em que a fonte foi conferida. Cálculo retroativo usa a tabela da competência, não a de hoje, e quando a data está fora da cobertura o motor recusa em vez de responder um número plausível e errado.

MCP readiness

B · 88/100

Readiness is how fully this listing follows its protocol and how it behaved in our probes over 30 days. It is shown for reference and does not move it in search. Search order and leaderboards use the separate quality grade (here C+, 71.2/100), which weighs availability, conformance, p95 speed and descriptor. How the two differ

Valid MCP handshake	10/10	initialize and tools/list both answered.
Live MCP endpoint	25/25	Endpoint answers the MCP initialize handshake (1921 ms).
Protocol revision	8/10	Speaks MCP 2025-11-25, 1 revision(s) behind 2026-07-28.
Signed descriptor	n/a	No MCP standard defines a signed server descriptor.
Uptime (30 days)	15/15	31/31 probes succeeded over 30 days (100%).
Tool declaration	10/10	Lists 60 tool(s) with descriptions.
Verified identity	5/10	Publisher declared (repository, package or homepage); claim this listing to verify domain control.
Freshness + modern flags	4/5	seen in a source within 7 days.
Auth declaration	2/5	Declares credential scheme: smithery_api_key.

Applicable criteria total 90 points, scaled to 100.

Responsiveness: Responsive (1921 ms; bands ≤2.5 s, ≤5 s, ≤8 s, slower; penalty only).

Measured 2026-11-11.

Nine criteria, the same as the A2A readiness score, read from our daily MCP probe (initialize + tools/list) and 30-day probe history. No MCP standard defines a signed server descriptor, so that criterion is n/a and the other 90 points are scaled to 100. Grades: A>=90, B>=75, C>=60, D>=40, F<40. Display only: search order uses the quality grade.

Compared with peers

Against 53,039 reachable MCP servers in our daily snapshot (2026-11-12 06:46 UTC). Display only; it does not change search order.

Readiness: Higher than 95% of peers; This listing 88 · peer median 81
Latency: Faster than 17% of peers; This listing 688 ms · peer median 326 ms

Where it loses the most points, and how to win them back

Verified identity −5 — Claim the listing and prove control of its domain.
Now: Publisher declared (repository, package or homepage); claim this listing to verify domain control.
Auth declaration −3 — State how to authenticate (an auth scheme, or that none is needed).
Now: Declares credential scheme: smithery_api_key.
Protocol revision −2 — Support the current protocol revision.
Now: Speaks MCP 2025-11-25, 1 revision(s) behind 2026-07-28.
