The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

fillout_remove_webhook unknown never probed

Stop a webhook from receiving submissions. Recoverable: create it again with fillout_create_webhook (it gets a new id). Fillout: POST /webhook/delete.

fillout_get_form unknown never probed

Fetch one form's metadata: every question (id, name, type), calculations, URL parameters, scheduling and payment fields, and quiz settings. Use the question ids to read answers or to create submissions. Fillout: GET /forms/{formId}.

fillout_list_submissions unknown never probed

List one page of a form's submissions (answers to every question, calculations, URL parameters, scheduling, payments, quiz score, login email), filtered by date range, status or free-text search. Offset pagination: the response carries totalResponses and pageCount. Fillout: GET /forms/{formId}/submissions.

fillout_count_submissions unknown never probed

Count a form's submissions matching the same filters as fillout_list_submissions (date range, status, search) without pulling the answers — e.g. 'how many responses this week?' or 'how many partial submissions?'. Reads totalResponses from GET /forms/{formId}/submissions with limit=1.

fillout_export_submissions unknown never probed

Fetch many submissions in one call by walking the offset pagination (150 per page, paced under Fillout's 5 requests/second limit), up to max_submissions. Same filters as fillout_list_submissions. Use this for analysis across a whole response set; the result says whether it was truncated. Fillout: GET /forms/{formId}/submissions (repeated).

fillout_create_submissions unknown never probed

Create up to 10 new submissions on a form, as if respondents had filled it in — e.g. to import responses collected elsewhere. Each submission needs its question answers (question ids from fillout_get_form); URL parameters, scheduling, payments, login email and timestamps are optional. Creates real records that trigger the form's integrations. Fillout: POST /forms/{formId}/submissions.

fillout_create_webhook unknown never probed

Subscribe a URL to a form's new submissions: Fillout will POST each submission (same shape as a fillout_list_submissions entry) to it. Returns the webhook id — keep it, it is the only handle for removing the webhook later. Fillout: POST /webhook/create.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/d4dcd71f20ad9421/badge.svg)](https://brick.blue/agent/d4dcd71f20ad9421)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know

card completeness

100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
