Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Runs an external command src/index.ts:159
                    execSync(`start "" "${wayStationPath}"`, { shell: 'cmd.exe' });
Builds a file path from a variable src/index.ts:19
    return fileName ? path.join(basePath, fileName) : basePath;

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Connect this server

Endpoint below is the one we actually reach during checks — not the one copied from a README. Last verified 5 min ago.

run in your terminal
claude mcp add postgres --transport http https://waystation.ai/postgres/mcp
Settings → Connectors → Add custom connector, then paste this address
https://waystation.ai/postgres/mcp

This endpoint answered with an authorization challenge. The server is running, but you need an API key from its owner to call it.

This server publishes 1 more address. The block above uses the one we reach during checks; the full list is under Endpoints below, and the author may intend a particular one for your client.

Postgres — questions

Answers built from our own checks of this server.

Why is there no tool list for Postgres?
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 Postgres working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 184 of 184 checks got a reply (100.0%), average response time 142 ms. The bar chart above shows every period we have measured.
Is Postgres still maintained?
No commits for 13 months. 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 Postgres?
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. You will need your own key: it refuses anonymous clients.
Does Postgres need an API key?
Yes. Every time we knock, Postgres answers with an authorization challenge instead of its tool list — that is how we know it is running and gated rather than broken. Bring your own credentials and it will talk.
How fast is Postgres?
It answers our handshake in 142 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.
Is Postgres open source?
We cannot say either way: written in JavaScript, 65 stars on GitHub and 2 open issues, but we could not determine the licence, and without one the code is not open source by default.
