Common questions

Is LeadMagic safe?

It passed 1 of 1 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?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (2.23.5) reached the registry 22 days 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?

LeadMagic for ChatGPT

The public LeadMagic package for ChatGPT and Codex, published by LeadMagic Corporation. It contains directory metadata, the hosted MCP connection at https://mcp.leadmagic.io/mcp, declared listing images, and the LeadMagic Tables skill. Authentication is configured in the OpenAI submission portal.

LeadMagic supports B2B account research, contact enrichment, table inspection and scoped cleanup, and connected CRM inspection. Available tools depend on the connected workspace's permissions. Paid table runs require a scope and credit quote followed by human approval. Outbound CRM and sequencer delivery is handled in the LeadMagic app.

Build

Requires Node.js 24.18+ and zip. Authored tooling uses TypeScript with Node's native type stripping; validation also runs the strict TypeScript compiler and package boundary tests.

npm ci

npm run validate npm run package -- --out=/tmp/leadmagic-openai-plugin.zip

Support: LeadMagic Support · Privacy · Terms

The validator requires the public author name and developer name to be exactly LeadMagic Corporation. It checks the stable plugin identity, listing limits, review tool names, and one hosted HTTPS MCP without embedded credentials, headers, or an authentication override. It rejects app references, lifecycle hooks, unsafe paths, symlinked package files, and obsolete paid-run instructions. This package uses noninterlaced PNG images, decoded with pinned pngjs after checking file size and dimensions. Declared screenshots must be distinct PNG assets, one per starter prompt, each 706 pixels wide and 400–860 pixels tall, at most 5 MiB.

The upload ZIP contains only the plugin manifest, MCP connection metadata, declared images, and the Tables skill. Packaging creates a fresh archive, so previous ZIP contents cannot survive. Registry metadata, build tools, repository files, and undeclared assets are excluded. Write the ZIP outside this repository. Keep reviewer credentials and sign-in instructions in the secure OpenAI review form; OpenAI rejects them in ZIP metadata.

To check review tool names against a saved MCP tools/list response or catalog:

npm run validate -- --tools=/absolute/path/tools-list.json

A local catalog verifies tool names only. It is not a fresh authenticated production scan.

Submit an update

Use the existing LeadMagic entry in the OpenAI submission portal and the With MCP flow. Preserve the package identity and existing authentication configuration, verify domain ownership, and scan the production endpoint. Screenshots require custom UI reported by that scan.

Run all five positive and three negative review cases using the review account and provide an accessible demo recording that demonstrates the current package. Local validation does not verify live tool behavior or complete directory review.

The demo recording is managed in the existing submission's Review information → Supporting content field. Set it to the current review recording and save the details. The manifest deliberately omits review.demo_recording_url so the dashboard value remains editable and can be verified before submission. Keep this public HTTPS recording accessible without sign-in, including byte-range requests from automated clients.

Official MCP Registry

server.json publishes LeadMagic's hosted MCP endpoint to the Official MCP Registry. It uses the io.leadmagic domain namespace and a Streamable HTTP connection; clients authenticate through the service's OAuth flow. This repository contains public connection and listing metadata only, not the hosted server implementation.

Validate the listing before publishing with mcp-publisher validate server.json.
