Quiet is not dead — but it is worth knowing when it wakes up, or when someone else takes it over. We watch the repository and tell you either way.

Simsima Connectivity — questions

Answers built from our own checks of this server.

What can Simsima Connectivity do?

It exposes 7 tools, read directly from the server on our last check. Among them: check_coverage, create_checkout_link, get_destination_info, get_plan, list_destinations, recommend_plan and 1 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 →

Is Simsima Connectivity 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 284 ms. The bar chart above shows every period we have measured.

Is Simsima Connectivity still maintained?

The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.

How do I connect Simsima Connectivity?

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 Simsima Connectivity need an API key?

No. Simsima Connectivity completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 7 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Simsima Connectivity?

It answers our handshake in 284 ms on average, which is faster than 52% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
