MCP Registry Validator — Check Endpoints Actually Resolve
io.github.operatorsheets/mcp-uptime · 0.2.1
Check an MCP endpoint resolves: liveness, live tool list, schema drift. Free.
Nobody here has read this server's code, because it publishes none. The description above is the maker's own, from the registry. A connection test shows whether it answers and what tools it says it has; it never calls a tool, so it cannot show what one does with your data.
Where it sits in the directory's order
What can be seen from outside, weighed as the directory publishes.
Observable signals: 35 of 100 points (at most 60 here)
| Input | Points | What was seen |
|---|---|---|
| Source published | held at 0 | No entry here publishes source: that is what puts it in this directory. |
| Licence stated | held at 0 | With no files, there is nothing for a licence to be stated in or held against. |
| Advisory state | held at 0 | Advisory databases index packages, and these entries publish none, so there is nothing to look up. |
| Auth declared | 0 of 15 | The registry entry declares no key. That is what it declares, not a finding that it has no protection. |
| Latest connection test reached it | 20 of 20 |

Connection test
The MCP handshake, then a request for the tool list, with no key and no data of yours. Run nightly, and by anyone, at most once every ten minutes per server.
It completed the handshake and listed 4 tools.

The tools it lists (4, as of 8 days ago)
The tool-description rules found nothing in these descriptions. They look for instructions aimed at a model and for hidden characters; they cannot see what a tool does when it runs.
check_mcp_endpointProbe an MCP endpoint right now: is it alive, which transport it speaks, how many tools it exposes, and whether its tool schema changed since the last check. Use before depending on a third-party MCP server.
get_uptimeUptime history for an MCP endpoint over the last N days (max 30), with incident windows. Reads stored history; does not probe.
get_known_toolsThe tool list last observed at an MCP endpoint, with the timestamp of the most recent schema change. Reads stored history; does not probe.
check_schema_driftProbe an MCP endpoint and diff its tool schema against the last stored snapshot: tools added, removed, or whose description/inputSchema changed. Schema drift fails quietly mid-run, which is why it is worth checking.
How this entry becomes a listing
For the maker. The catalogue lists what it can read, and this server publishes nothing to read yet. There are two routes, and only the first is open today.
Publish the source Open today
- Put the server's source in a public repository on github.com, with a licence.
- Keep a server.json in that repository naming this server,
io.github.operatorsheets/mcp-uptime, and declare the repository in it:"repository": { "url": "https://github.com/owner/repo", "source": "github" }, adding"subfolder"when the server lives in a folder. - Publish that version to the official MCP registry.
- The nightly registry sweep records the declaration. This page stays, dated, and says the source is declared but not yet read.
- The catalogue reads declared repositories at a pinned commit, in batches run by hand, and lists the servers that meet the batch's rules (among them a server.json at that commit naming the server, an https endpoint and a licence). When it lists this server, this page links to the listing. There is no schedule, so no date can be promised.
