Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

stats
get_stats
The list in numbers: five aggregates of the listed companies (category, funding stage, headquarters, founded year, minimum disclosed funding), each with n, coverage, caveat, method, as-of date, CSV and chart URL. CC BY 4.0 with attribution.
get_stats_history
Quarterly snapshots of the same aggregates and one series per chart across snapshots. Never interpolated: one snapshot is one point. CC BY 4.0 with attribution.
categories
list_categories
List every security-company category with its slug, description, company count and page URL.
listed
check_if_listed
Check whether a company appears in the directory (name or slug contains the text). When it does not, the result says how a person can get it listed.
startup
get_startup
Get one listed company by slug (or exact name): every public field plus its page URL.
startups
search_startups
Search the Security Startups directory of young security companies. Filters combine with AND. Returns public fields and each company's page URL, alphabetical by name (not a ranking).

Security Startups — questions

Answers built from our own checks of this server.

What can Security Startups do?
It exposes 6 tools, read directly from the server on our last check. Among them: check_if_listed, get_startup, get_stats, get_stats_history, list_categories, search_startups. 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 →
Is Security Startups working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 859 ms. The bar chart above shows every period we have measured.
How do I connect Security Startups?
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.
Does Security Startups need an API key?
No. Security Startups completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 6 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Security Startups?
It answers our handshake in 859 ms on average, which is faster than 7% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
