Add to your claude_desktop_config.json:

`json
{
"mcpServers": {
"maybethisone": {
"command": "npx",
"args": ["maybethisone-mcp"]
}
}
}
`

Or if installed locally:

`json
{
"mcpServers": {
"maybethisone": {
"command": "node",
"args": ["/path/to/maybethisone/dist/mcp.js"]
}
}
}
`

Limitations

- npm package names: npm normalizes package names (e.g., my-pkg and my_pkg` are considered the same) and private packages are not visible, so even if the exact name appears available, publishing may still fail
- Domain checks: Uses DNS lookup which may show false positives for registered domains without DNS records
- Rate limiting: Some platforms may rate limit requests if checking many names
- Bot protection: Twitter/X, LinkedIn, and npm org checks use Playwright to bypass Cloudflare/bot protection
