Nothing serious here today

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

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

server

check_server

Probe a remote MCP server URL once, credential-free and without calling its tools, and get its quality checks and its readiness for the Claude and OpenAI directories. Pass `url` to start a check (waits up to 25 s for the result), or `id` to read one. Quota: a few checks per hour anonymously, more with an API key.

get_server

Official server.json plus connectability (class, remotes with auth/health, packages), current tools, trust breakdown and identity for one server name.

connection

get_connection

Minimal connection block for the preferred remote (or package) with ${SECRET} placeholders, formatted for a target client. Secrets are never accepted or returned.

search

Hybrid (keyword + semantic) search over servers and their tools. Filter by connection class to keep only what you can reach autonomously (R0, R1).

tools

list_tools

Every current tool of a server with full input/output schemas, paginated by tool name.

protogrid — questions

Answers built from our own checks of this server.

What can protogrid do?

It exposes 5 tools, read directly from the server on our last check. Among them: check_server, get_connection, get_server, list_tools, search. 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 protogrid 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 369 ms. The bar chart above shows every period we have measured.

How do I connect protogrid?

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 protogrid need an API key?

No. protogrid completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is protogrid?

It answers our handshake in 369 ms on average, which is faster than 35% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
