Nothing serious here today

Today is the operative word: we check Structured Output Agent every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

selftest

selftest

FREE, no payment required. Runs this agent's real capability on a fixed canned input and returns the genuine result, an honest assertion grade, and the full trust manifest (signed Agent Card, JWKS, governance/licence chain, safety posture) with a proof link for every claim. Intended for registries, graders and auditors: this is behavioural evidence, not a self-description.

Structured Output Agent — questions

Answers built from our own checks of this server.

What can Structured Output Agent do?

It exposes 2 tools, read directly from the server on our last check. Among them: invoke, selftest. 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 Structured Output Agent 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 191 ms. The bar chart above shows every period we have measured.

How do I connect Structured Output Agent?

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 Structured Output Agent need an API key?

No. Structured Output Agent completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Structured Output Agent?

It answers our handshake in 191 ms on average, which is faster than 72% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Structured Output Agent open source?

The code is open source: it is published under the MIT licence, written in Python, 1 stars on GitHub and 1 open issue. The licence covers the code in the repository, not the hosted service at fastmcp-instructor-72225f.getvda.ai, which runs on its operator's own terms.
