NeverBounce + Gemini
Validate single emails or run bulk-list verification jobs via NeverBounce. 6 tools, query-string API-key auth.
Prerequisites
See the full setup instructions baked into the connector (visible in the in-app store when you select the connector). The required environment variables for this connector are:
NEVERBOUNCE_API_KEY
Step 1 — Get credentials
2 (developers.neverbounce.com).
Setup:
- Sign in to https://app.neverbounce.com → Apps → New API Key.
- Copy the key. Set
NEVERBOUNCE_API_KEY.
Authentication: query-string ?key=.... NeverBounce also supports a custom Auth header but query-string is the primary.
Single vs Bulk:
neverbounce_single_check: synchronous single-email verification. ~1 credit. Returns result (valid/invalid/disposable/catchall/unknown) + flags + suggested_correction.neverbounce_create_job: async bulk verification of a list (up to 1M emails). Returns job_id; poll status withneverbounce_job_statusuntil status='complete'; thenneverbounce_job_resultsto fetch.
…(continued in the in-app connector instructions)
Step 2 — Install the adapter
git clone https://github.com/HelpCode-ai/anythingmcp.git
cd anythingmcp && docker compose up -d
Step 3 — Add the connector in Gemini
Gemini CLI reads MCP servers from ~/.gemini/settings.json (or %APPDATA%\gemini\settings.json on Windows). Add:
{
"mcpServers": {
"anythingmcp": {
"httpUrl": "https://cloud.anythingmcp.com/mcp",
"headers": { "Authorization": "Bearer YOUR_MCP_API_KEY" }
}
}
}
- Get your MCP API key from AnythingMCP → Profile → MCP API Keys → New Key.
- Save the file and restart
gemini. - Run
/mcpinside the Gemini CLI —NeverBounceshould be listed as available. - Vertex AI Studio: pass
https://cloud.anythingmcp.com/mcpto thetoolsarray of your request with the same Bearer header.
