Supabase 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.

Endpoint below is the one we actually reach during checks — not the one copied from a README. Last verified 4 min ago.

run in your terminal
claude mcp add mcp --transport http https://mcp.supabase.com/mcp
~/Library/Application Support/Claude/claude_desktop_config.json
{
  "mcpServers": {
    "mcp": {
      "url": "https://mcp.supabase.com/mcp"

}

This one needs environment variables set before it will start: SUPABASE_ACCESS_TOKEN (Personal access token for Supabase API). The author declared them in the registry entry; get the values from the project itself.

This endpoint answered with an authorization challenge. The server is running, and it signs you in through your browser: there is no API key to paste.

Supabase — questions

Answers built from our own checks of this server.

Why is there no tool list for Supabase?
The server answered our handshake with an authorization challenge, so it is running — but it will not describe its tools to an anonymous client. To see them you need to connect with your own credentials. We record it as alive, not as broken: 100.0% of checks in the last 24 hours got a reply.
Is Supabase working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 87 ms. The bar chart above shows every period we have measured.
How do I connect Supabase?
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. You sign in through your browser once and the client keeps the session: no key to copy, and it refuses anonymous clients.
How do you sign in to Supabase?
No API key is involved. Supabase answers our knock with an OAuth challenge, so you authorise it once in your browser and the client keeps the session. That is also why we see no tool list: it will not describe itself to an anonymous client, and that is the server working as intended, not a fault.
How fast is Supabase?
It answers our handshake in 87 ms on average, which is faster than 85% 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.
How many people use Supabase?
The npm package @supabase/mcp-server-supabase was installed 76 349 times in the last week. Week over week that is -16%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Supabase open source?
Yes — it is published under the Apache-2.0 licence, written in TypeScript, 2 913 stars on GitHub and 73 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
