giggal-ai/giggal-mcp

Available on Smithery
Verify catch-all, accept-all, and SEG-protected email addresses without leaving Claude, ChatGPT, Cursor, VS Code, or any other MCP client. This is the official Model Context Protocol server for Giggal.ai, the catch-all email verification tool that confirms the mailboxes other verifiers write off as "risky" or "unknown."
Why Giggal.ai
Most tools give up on the hard addresses. Giggal.ai runs a deep mailbox existence check over SMTP and returns a real deliverability result where others cannot:
- **Catch-all and accept-all domains** that accept every address, even for users who do not exist
- **SEG-protected inboxes** behind Proofpoint, Mimecast, and Barracuda that block the checks most verifiers rely on
- **Risky B2B contacts** that competitors flag and discard, around 30% of a typical list, recovered as deliverable
99% accuracy on standard business lists and bounce rates under 3%, straight from your AI assistant.
Get an API key
Sign up at emailverifier.giggal.ai for **1,000 free verification credits, no card required**, then copy your key from the **Developer API** tab. Claude and ChatGPT connect over OAuth and need no key. The IDE and CLI clients below use the key as a Bearer token.
Connect your AI client
Claude
Add Giggal.ai as a custom connector. No config files, no API key.
1. Open **Settings → Connectors** (web or desktop).
2. Click **Add → Add custom connector**.
3. Name it **Giggal.ai**, paste the MCP URL, then click **Add**.
4. Open the **Giggal.ai** connector and click **Connect**.
5. Click **Allow** to grant verify:read (verify addresses, check credits, look up past verifications).
ChatGPT
Add Giggal.ai as a custom plugin, connected over OAuth.
1. Open **Plugins** from the sidebar, then click the **+** in the top right.
2. Name it **Giggal.ai**, set **Server URL** to the MCP URL, choose **Authentication → OAuth**, tick the confirmation, then click **Create**.
3. Open the plugin, click **Connect**, then **Sign in with Giggal.ai**.
4. Click **Allow** to grant verify:read.
Claude Code
Already have a giggal server? Run claude mcp remove giggal --scope user first, then re-add.
Cursor, Windsurf, and Cline
Add this to your MCP config file:
- Cursor: ~/.cursor/mcp.json (or .cursor/mcp.json per project)
- Windsurf: ~/.codeium/windsurf/mcp_config.json
- Cline: cline_mcp_settings.json (open it from the Cline MCP settings)
VS Code
Add to .vscode/mcp.json. VS Code uses servers instead of mcpServers:
Zed
Add to ~/.config/zed/settings.json:
Codex
Add to ~/.codex/config.toml:
Codex reads the key from an env var. Set it and reload your shell, then fully quit and reopen Codex:

Restart the client after adding, then just ask:
