Nothing serious here today

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

Available tools 2

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

inspect

inspect_endpoint

Connects to a remote MCP endpoint (Streamable HTTP, then legacy SSE), lists its tools, and classifies each tool's side effects from its MCP hints. Never calls a tool on the target. agent_readiness lists what is wrong with the tool definitions and protocol compliance of the target, each with a fix, and a grade A-F. A target problem is status=failed with a stable failure code (e.g. TARGET_UNAVAILABLE, TARGET_AUTH_FAILED, MCP_PROTOCOL_ERROR). Private and loopback addresses are rejected.

pricing

get_pricing

MCP Canary plans, monthly prices (in cents), and limits, plus the free trial. The trial needs no payment and starts on the first monitor write.

MCP Canary — questions

Answers built from our own checks of this server.

What can MCP Canary do?

It exposes 2 tools, read directly from the server on our last check. Among them: get_pricing, inspect_endpoint. 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 MCP Canary 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 564 ms. The bar chart above shows every period we have measured.

How do I connect MCP Canary?

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 MCP Canary need an API key?

No. MCP Canary 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 MCP Canary?

It answers our handshake in 564 ms on average, which is faster than 20% 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.
