This endpoint answered with an authorization challenge — the server is running, but you need an API key or OAuth to use it.

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 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 91 of 91 checks got a reply (100.0%), average response time 196 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 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 key or an OAuth login: it refuses anonymous clients.

Does Library need an API key?

Yes. Every time we knock, Library 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 Library?

It answers our handshake in 196 ms on average, which is faster than 64% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
