NeverBounce + Claude
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
curl -fsSL https://raw.githubusercontent.com/HelpCode-ai/anythingmcp/main/docker-compose.quickstart.yml -o docker-compose.yml
printf 'JWT_SECRET=%s\nENCRYPTION_KEY=%s\n' "$(openssl rand -hex 32)" "$(openssl rand -hex 32)" > .env
docker compose up -d
Step 3 — Add the connector in Claude
Your server URL: in AnythingMCP, open MCP Servers → the server this connector is on, and copy its URL (
https://cloud.anythingmcp.com/mcp/…). Use it wherever this guide showsYOUR_SERVER_ID.
Recommended path — works on claude.ai web without editing any config file.
- In Claude, open Customize → Connectors.
- Click +, then Add custom connector.
- Enter a name, e.g.
NeverBounce, and the remote MCP server URLhttps://cloud.anythingmcp.com/mcp/YOUR_SERVER_ID, then click Add. - Click Connect and sign in to AnythingMCP (OAuth) to allow access.
