One OAuth login adds Zephex's ten developer tools to Claude.ai — works on web, Desktop, mobile, and Cowork. No API key. No terminal. No manual config.
1. Open Claude
On Claude.ai web and Claude Desktop: click the gear icon → Settings → Connectors.
On mobile: open the side menu → Settings → Connectors.
2. Click "Add custom connector"
You'll see a dialog asking for the server URL.
3. Enter the URL
https://zephex.dev/mcp
4. Click "Connect"
Claude opens a browser to zephex.us.auth0.com for sign-in. Use your Zephex account credentials, or sign up if you don't have one yet.
5. Approve the consent screen
You'll be asked to approve the scopes mcp:read and mcp:write. Click Approve.
6. Done
You're returned to Claude with the connector active. Try it: ask Claude "Use audit_headers on https://example.com" or "Use check_package to verify the npm package 'react'".
See /docs/reviewer for step-by-step test instructions, including the pre-provisioned reviewer test account and what to expect from each tool.
For Cursor, Claude Code, VS Code, Windsurf, JetBrains, and 14 other MCP-compatible editors, use the one-command installer:
npx zephex setup
See /install for full instructions.
Free tier includes 300 requests/month — enough to evaluate every tool. Pro is $7/mo (3,500 requests), Max is $19/mo (10,000 requests). See /pricing.
Make sure the URL is exactly https://zephex.dev/mcp (no trailing slash). If your network blocks Auth0, the OAuth flow won't complete — try from a different network.
Refresh the page and try again. If it persists, sign out of Zephex in another tab and try the connection again — fresh sessions usually fix transient OAuth state issues.
For tools that need a project (get_project_context, scope_task, read_code, find_code, explain_architecture), pass either a GitHub URL like github:owner/repo or paste relevant files via Claude's file upload. Cloud-runnable tools (audit_headers, check_package, audit_package, keep_thinking, Zephex_dev_info) don't need any setup.
