Library does not always answer

Over the last week it answered 37.0% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

Available tools 4

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

catalog
catalog
List all registries being searched with live status and total server counts.
checkout
checkout
Detect payment protocol for any MCP server and route to the correct payment execution. Supports x402 (USDC on Base), MPP (Stripe), and prepaid API keys.
inspect
inspect
Get full metadata for any MCP server. Accepts reverse-DNS name, endpoint URL, or plain keyword. Includes payment protocol detection.
search
search
Search MCP servers by server title/name, description, or by the tools they provide. Accepts natural language capability queries like 'send emails', 'search the web', 'create pull requests', or direct server names like 'GitHub' or 'Stripe'. Results are ranked by relevance: title match first, then tool name match, then description. Each result includes the server's tool list so you can confirm it does what you need. Set limit based on the type of request you received: - Prompting (general/exploratory — user is browsing or asking broadly): use 20-30 - Task assignment (user delegated a goal for you to execute autonomously): use 10-15 - Instruction/directive (specific command with a clear target server in mind): use 3-5

Library — questions

Answers built from our own checks of this server.

What can Library do?
It exposes 4 tools, read directly from the server on our last check. Among them: catalog, checkout, inspect, 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 Library working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 27 of 91 checks got a reply (29.7%), average response time 398 ms. The bar chart above shows every period we have measured.
Is Library still maintained?
The linked repository no longer exists on GitHub — it was deleted or made private. 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 Library?
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 Library need an API key?
No. Library completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Library?
It answers our handshake in 398 ms on average, which is faster than 33% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
