Catalog

What catalog does

The catalog MCP server exposes public, read-only information about Russian microfinance organizations listed in the Bank of Russia state registry. Its data comes from ZaimHub, a Russian microloan comparison marketplace. Responses include a canonical_url for the corresponding page on zaimhub.com, which should be cited when using the data.

The service is intended for research, comparison, and information retrieval. It does not submit loan applications, modify records, or provide account access. ZaimHub notes that displayed terms can change, so the linked page is the place to verify final conditions. The catalog is not financial advice.

How it works

The catalog MCP server uses a public, stateless Streamable HTTP endpoint:

https://zaimhub.com/api/mcp

Clients send MCP requests over HTTP and do not need an API key or OAuth flow. The server language is Russian. A standard MCP client can connect by registering the endpoint as a remote Streamable HTTP server. The service allows up to 60 requests per minute per IP; additional requests may receive HTTP 429.

Search results distinguish confirmed, negative, and unknown first-loan zero-interest status with true, false, or null. Offer responses also report the total number of matches and whether the returned set was truncated. Empty fields in full MFO records are omitted.

Tools and capabilities

The catalog MCP server provides these operations:

• list_mfo returns MFOs ordered by borrower-rating position, with quick terms and canonical card URLs. The optional result limit defaults to 50.
• get_mfo retrieves an MFO by slug, including new- and repeat-client terms, loan amounts and durations, rates, total cost of credit, borrower requirements, fees, legal entity data, OGRN, registry number, rating criteria, and update date.
• search_offers finds first-loan offers by optional amount, term in days, and zero-interest preference. Its default limit is 15.
• list_categories returns the site’s category groups and the selection rule for each category.
• get_category retrieves one category by slug, including its criterion, sorting, and per-MFO offer table.
• get_reviews returns recent borrower reviews for an MFO, with ratings, dates, and text. Its maximum limit is 50 and default is 10.
• get_market_rules returns Russian microlending legal context, including rate and total-cost limits, self-ban information, cooling-off periods, debt collection rules, and the date of the latest review.

Setup and configuration

Add the remote endpoint to an MCP client using a configuration such as:

{
  "mcpServers": {
    "zaimhub-catalog": {
      "type": "streamable-http",
      "url": "https://zaimhub.com/api/mcp"
    }
  }
}

Claude users can add a custom connector named ZaimHub catalog with the same URL. No environment variables or credentials are required. MCP Inspector can verify connectivity with its HTTP transport and the tools/list method.
