Saymon RU Data API — questions

Answers built from our own checks of this server.

What can Saymon RU Data API do?

It exposes 20 tools, read directly from the server on our last check. Among them: cbr_rates, company_report, fns_npd_check, inn_lookup, moex_quote, pochta_address and 14 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is Saymon RU Data API mostly used for?

Its tools cluster around pochta and research. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is Saymon RU Data API working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 210 ms. The bar chart above shows every period we have measured.

Did Saymon RU Data API ever remove tools?

Yes. claude_opus_5_chat, gpt_5_6_sol_chat are no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.

How do I connect Saymon RU Data API?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Saymon RU Data API need an API key?

No. Saymon RU Data API completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 20 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Saymon RU Data API?

It answers our handshake in 210 ms on average, which is faster than 68% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
