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 access to your Zephex account (standard sign-in scopes). 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 555 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, check_test, 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, project_memory, keep_thinking, Zephex_dev_info) don't need any setup.
