Which MCP Server Should You Choose?
C
Choose Catalog when:
You need dedicated capabilities in the Developer Tools domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
All MFOs in the catalog with borrower rating and canonical card URLs. `rating: null` means *no reviews yet*, not a low score.
get_mfo
Full MFO card: terms for new and repeat clients (amount, term, rate), effective annual rate (ГЭСВ), requirements, fees, legal data (legal entity, BIN, ARDFM license number and a direct link to the company's record in the regulator's license register), 4-criteria rating, record update date.
search_offers
Matching first-loan offers with terms and `first_loan_zero_percent: true/false/null` (null = unconfirmed). Calling without filters returns the whole catalog — prefer passing `amount`/`term_days`.
list_categories
Catalog selections grouped by section (popular, by payout method, by amount and term, by borrower category), each with its selection criterion.
