Perplexity

Verify single sign-ups on the fly with Claude Desktop

Stop wasting credits on bad data. This MCP Server lets your Claude Desktop client run instant checks using the `check_email` tool against the NeverBounce API. You get real-time validation without leaving your conversation. It checks syntax, DNS records, and mail server responses instantly. Your agent tells you right away if an address is safe, disposable, or dead, so you don't send emails to a black hole.

Manage bulk verification jobs directly in chat

Handling thousands of leads used to mean manual CSV uploads. Now, you can point your AI client to a remote file with `create_job_from_url` or dump raw text using `create_job_from_input`. Once the job starts with `start_job`, you can monitor its progress using `get_job_status`. This MCP Server lets you run massive list cleaning operations directly through simple chat commands.

Fetch results and audit lists without the dashboard

Skip logging into the web portal to retrieve your clean lists. Have your agent run `get_job_results` to bring verified data straight into your workspace. You can also run `list_jobs` to see past runs or `delete_job` to purge old data. It keeps your workspace tidy while letting you inspect your credit balance with `get_account_info` whenever you need.
