Theta Vantage — questions

Answers built from our own checks of this server.

Why is there no tool list for Theta Vantage?

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: 97.8% of checks in the last 24 hours got a reply.

Is Theta Vantage working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 88 of 90 checks got a reply (97.8%), average response time 1179 ms. The bar chart above shows every period we have measured.

How do I connect Theta Vantage?

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 will need your own credentials: it refuses anonymous clients.

Does Theta Vantage need an API key?

Yes. Every time we knock, Theta Vantage 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 Theta Vantage?

It answers our handshake in 1179 ms on average, which is faster than 8% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
