SUBSTRATE — questions

Answers built from our own checks of this server.

Is SUBSTRATE 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 300 ms. The bar chart above shows every period we have measured.
How do I connect SUBSTRATE?
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 SUBSTRATE need an API key?
No. SUBSTRATE completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. This is what we observed, not what the docs claim.
How fast is SUBSTRATE?
It answers our handshake in 300 ms on average, which is faster than 46% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use SUBSTRATE?
The npm package substrate-mcp was installed 51 times in the last week. Week over week that is +50%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is SUBSTRATE open source?
Yes — it is published under the NOASSERTION licence, written in JavaScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
