What data it sees

Do you need an account

No: the server works without sign-in

Doorman keeps sales pitches, bots, fake sign-ups and card testers out of website forms, with no captcha. Each submission is judged in about 100 ms and every drop comes with the sentence that gave it away, rescuable in one click.

This server lets a coding agent do the whole setup: create the account, create a form endpoint per form on the site, fetch the install snippet for the stack (HTML, React, Next.js, Express, Python, Ruby, Elixir, Webflow, Framer), send test submissions, check delivery to email, Slack or a webhook, and review or relabel held submissions later.

No key needed to start: doorman_signup creates an account and returns an API key; pass it as api_key to the other tools. Already have one? Get it from https://withdoorman.com/app#/settings.

doorman_docs	Read how Doorman works and how to integrate it (the same text as /llms.txt). Call this first if you haven't used Doorman before.
doorman_signup	Create a Doorman account for the user with a first form and an API key. Ask the user for their email first. They'll get an email to set a dashboard password. Creates the account's first form too and returns its id and action URL, plus the api_key (store it as DOORMAN_KEY in the project's local secrets file, never commit it). Only for new users: if they already have an account, ask for a key instead. Until the user clicks the confirmation link in that email, nothing is emailed to them (100 checks; Slack and webhooks work).
doorman_whoami	Account, plan and this month's usage.
doorman_list_forms	List the account's forms with their action URLs and settings.
doorman_create_form	Create another form endpoint (one per distinct form on the site: contact, demo request, checkout, comments).
doorman_update_form	Change a form's settings: context, destinations, thresholds, watch mode, allow/block lists.
doorman_get_install_snippet	Get ready-to-paste integration code for a form on a given platform. Use 'html' for static sites, 'react' for SPA client components, and 'fetch' (plain fetch with timeout and fallback: Workers, Node, Next, Deno), 'nextjs', 'express', 'python', 'ruby' or 'elixir' when the form already posts to the project's own backend.
doorman_test_submission	Judge a sample message against a form's settings. Free, not forwarded, not counted. Use it to show the user Doorman working after setup (try one genuine enquiry and one sales pitch).
doorman_send_test_delivery	Send a sample delivery to the form's email/Slack/webhook destinations and report whether each one worked.
doorman_list_submissions	Recent submissions with their verdicts. Use review=true for held ones waiting for a human.
doorman_label_submission	Mark a submission real (delivers it if it was held or dropped) or spam.
doorman_contact_support	Stuck, or something isn't working? Send the problem straight to Doorman's founder, with the error you hit. Your account context (plan, forms, recent errors, never keys) is attached, and the reply goes to the account email. Use it instead of guessing at a fix.
