This is worth installing only if your agent writes to addresses it did not get from a trusted source — a form submission, a scraped page, a user typing under time pressure. The validation is the provider's, so the accuracy question is AbstractAPI's rather than this server's.
A single-purpose validator. It checks an address's format, whether the domain resolves, and whether the mailbox is deliverable, using AbstractAPI's email validation service.
- One check that answers whether an address is real: syntax, domain validity and deliverability, returned in a single call so an agent can decide before it drafts anything
Python 3.11.0 or higher and UV 0.6.9 or higher. Clone the repository, create the virtual environment with `uv venv`, and register it in the client as `uv --directory <path> run server.py`. An AbstractAPI key goes in a .env file as ABSTRACT_API_KEY; the free tier covers casual use. Published on PyPI as verify-mail, version 0.1.0.
