Regulatory Filings MCP — questions

Answers built from our own checks of this server.

What can Regulatory Filings MCP do?

It exposes 17 tools, read directly from the server on our last check. Among them: detect_insider_cluster, get_13f_delta, get_analyst_targets, get_dividend_aristocrats, get_earnings_calendar, get_earnings_estimates and 11 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 Regulatory Filings MCP mostly used for?

Its tools cluster around form and earnings. 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 Regulatory Filings MCP 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 114 ms. The bar chart above shows every period we have measured.

How do I connect Regulatory Filings MCP?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address. You will need your own credentials: it refuses anonymous clients.

Does Regulatory Filings MCP need an API key?

Yes. Every time we knock, Regulatory Filings MCP answers with an authorization challenge instead of its tool list — that is how we know it is running and gated rather than broken. Bring your own credentials and it will talk.

How fast is Regulatory Filings MCP?

It answers our handshake in 114 ms on average, which is faster than 91% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
