This endpoint answered with an authorization challenge. The server is running, but it did not say what kind of credentials it expects.

Available tools 5

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

categories
list_categories
List industry and function categories and how many servers are in each.
server
get_server
Return one server's metadata, status, latency, checks, and tool list. check_cadence is the median gap between probes over 7 days ('checked about every 6 hr'), or null when fewer than 3 probes were stored. next_check_at is omitted when that sample is missing or the server is overdue.
servers
search_servers
Search the server directory. Results include measured timestamps and the server page URL. Ranked by checks passed. These are automated measurements, not a rating.
status
check_status
Return the latest probe outcome, the observed check cadence from the last 7 days, and the server page URL. The cadence is null until 3 probes are stored. An overdue server has no promised next check.
tools
find_tools
Find servers whose measured tools match a capability. Results are grouped by server and include page URLs.

MCP Heartbeat — questions

Answers built from our own checks of this server.

What can MCP Heartbeat do?
It exposes 5 tools, read directly from the server on our last check. Among them: check_status, find_tools, get_server, list_categories, search_servers. 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 MCP Heartbeat 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 142 ms. The bar chart above shows every period we have measured.
How do I connect MCP Heartbeat?
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 MCP Heartbeat need an API key?
Yes. Every time we knock, MCP Heartbeat 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 MCP Heartbeat?
It answers our handshake in 142 ms on average, which is faster than 88% 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.
