Cross-Rail Settlement Binder missed one check this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

Cross-Rail Settlement Binder — questions

Answers built from our own checks of this server.

What can Cross-Rail Settlement Binder do?
It exposes 4 tools, read directly from the server on our last check. Among them: binder_append, binder_seal, binder_verify, health. 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 Cross-Rail Settlement Binder working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 90 of 91 checks got a reply (98.9%), average response time 442 ms. The bar chart above shows every period we have measured.
How do I connect Cross-Rail Settlement Binder?
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 Cross-Rail Settlement Binder need an API key?
No. Cross-Rail Settlement Binder completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Cross-Rail Settlement Binder?
It answers our handshake in 442 ms on average, which is faster than 29% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
