MCPLookup does not always answer

Over the last week it answered 2.7% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

Available tools 3

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

resolve

resolve_server

Resolve a named MCP server, vendor, product, package, repository, Registry identifier, or endpoint to a canonical MCPLookup identity. Returns at most five reviewed candidates with query-relative identity and publisher explanations, a compact trust assessment, and current connection options. This is the best fit when a particular artifact or product is known; find_servers covers open-ended capability discovery, while trust_lookup returns the full current evidence record for an exact canonical name.

servers

find_servers

Find a compact, trust-aware shortlist for a task or capability when no particular MCP server or product is known. Search by free text or MCPLookup's normalized capability taxonomy, with optional filters. Free text returns a reviewed identity-only slate when available; otherwise results are explicitly labelled catalog matches, and the two evidence lanes are never mixed. Returns at most five results with no pagination. A selected exact server name can be passed to resolve_server for reviewed identity context and connection options; named artifacts fit resolve_server directly.

trust

trust_lookup

Return MCPLookup's complete current trust record for one exact canonical MCP server name. Includes the verdict, Trust Index band and 0–100 score with confidence, coarse safety, maintenance, adoption, and provenance bands, coverage, freshness, public evidence, and citation. This fits trust questions and evidence review after identity is known; resolve_server handles ambiguous names or coordinates. Current state only—no history or safety certification.

MCPLookup — questions

Answers built from our own checks of this server.

What can MCPLookup do?

It exposes 3 tools, read directly from the server on our last check. Among them: find_servers, resolve_server, trust_lookup. 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 MCPLookup working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 91 checks got a reply (0.0%), average response time 106 ms. The bar chart above shows every period we have measured.

The registry lists MCPLookup as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect MCPLookup?

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 MCPLookup need an API key?

No. MCPLookup completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.

How many people use MCPLookup?

The npm package @mcplookup/mcp was installed 63 times in the last week. Week over week that is -32%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is MCPLookup open source?

The code is open source: it is published under the MIT licence, written in JavaScript and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at mcplookup.com, which runs on its operator's own terms.
