Common questions

Is MCPLookup safe?

It passed 4 of 4 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed 3 months ago, and the latest version (0.1.6) reached the registry 3 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

MCPLookup MCP

The official stdio compatibility wrapper for the MCPLookup remote MCP server—the independent trust layer for MCP.

The canonical server is https://mcplookup.com/mcp. It provides three anonymous, read-only tools:

resolve_server resolves a title, package, endpoint, or name to a canonical server.
find_servers finds up to five servers using MCPLookup's normalized taxonomy.
trust_lookup returns the current Trust Index, verdict, evidence, and citation.

This package exists for MCP clients that require a local stdio command. It forwards MCP messages to the canonical hosted server without implementing scoring, storing evidence, adding authentication, or changing tool results.

Connect

Connect directly when your client supports remote Streamable HTTP:

https://mcplookup.com/mcp

Use this package when your client requires a local stdio command:

Node.js 20 or newer is required. No API key or environment variable is needed.

npx -y @mcplookup/mcp

Generic MCP client configuration:

"mcpServers": { "mcplookup": { "command": "npx", "args": ["-y", "@mcplookup/mcp"] } } }

Prefer a direct Streamable HTTP connection to https://mcplookup.com/mcp when your client supports remote MCP servers. The package is a transport adapter, not a separate service.

MCP Registry

MCPLookup is listed in the official MCP Registry as com.mcplookup/mcp. The name is verified through DNS control of mcplookup.com.

One entry covers both connection paths, so a client installing from the Registry can use whichever it supports:

Path	Declaration
Canonical remote	`streamable-http` → `https://mcplookup.com/mcp`
Compatibility package	npm `@mcplookup/mcp`, `stdio` transport

The entry declares no environment variables, headers, or credentials, matching the anonymous public interface. server.json in this repository is the source of that metadata.

What stays remote

The wrapper contains no trust scores, evidence database, taxonomy, authentication system, or scoring logic. MCPLookup evaluates public evidence at the canonical service and returns the same bounded, current-state response whether a client connects directly or through this stdio adapter.

The MIT license covers the plugin and wrapper software in this repository only. It does not license MCPLookup's hosted evidence database, assessments, verdicts, scores, classifications, taxonomy, historical record, or scoring framework. Use of service data remains governed by the MCPLookup terms.

Data and security

The wrapper has no credentials and writes no local data. Requests are sent to MCPLookup's hosted endpoint, where bounded security and product telemetry are processed under the MCPLookup privacy policy. See the MCP documentation for the public interface contract.

Report security issues according to SECURITY.md. For product support, email hello@mcplookup.com.

Bug reports and narrowly scoped compatibility improvements are welcome. See CONTRIBUTING.md before opening a pull request.

Development

npm test

npm pack --dry-run

The package intentionally has zero runtime dependencies.

Marketplace package

This repository also contains the shared MCPLookup marketplace package:

.claude-plugin/plugin.json and .mcp.json package the remote server for Claude.
.codex-plugin/plugin.json packages the same remote server for ChatGPT and Codex.
skills/verify-mcp-server/SKILL.md adds the proactive pre-connect verification workflow.
review/marketplace-cases.md defines the positive, negative, and direct-connect release cases.

The skill improves orchestration but is not required for correct tool selection. Direct MCP, Registry, npm-wrapper, and VS Code clients receive independently useful tool descriptions and server instructions from the canonical hosted service.
