api record

Zovo Graph Paper makes printable technical and note-taking paper as vector PDFs with lines at true physical spacing: square graph paper, dot grid, isometric, hex, polar, semi-log, log-log, engineering, coordinate planes, lined, Cornell notes, music staff, guitar tab and calligraphy guides. Call generate_graph_paper for grids and generate_note_paper for lined, Cornell, music and calligraphy pages, once per request, without asking follow-up questions for optional settings. Tell the user to print at 100% (Actual size) and give the PDF link.

_ is it live, free and safe measured by this hub
Is graph-paper live?
Yes — it answered the hub's last check (checked 14h ago). It answered 100% of checks over the last 30 days.
Is graph-paper free to use?
Yes — the hub reached it with no key and no payment.
What tools does graph-paper have?
2 tools: generate_graph_paper, generate_note_paper.
Is graph-paper safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

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.

    Use this when the user wants a printable lined paper, Cornell notes template, music staff paper, guitar tab paper or calligraphy guide sheet as a PDF. Lined paper is wide, college or narrow ruled or any spacing; Cornell notes have a cue column, notes area, summary box and name/date/topic header; music staff paper sets staves per page; calligraphy guides set x-height, ascender:x-height:descender ratio and slant angle. Does not make letter tracing or handwriting practice worksheets.

    Use this when the user wants printable graph paper or grid paper as a PDF: square grid (1/4 inch, 5 mm, 1 mm, 4x4 or 5x5 per inch), dot grid, isometric or isometric dot, hexagon, polar, semi-log or log-log with chosen cycles, engineering paper, or a coordinate plane with numbered x and y axes. Lines are placed at true physical spacing and the grid is centred, with a calibration ruler. Up to 100 pages, Letter, Legal, Tabloid, A5, A4 or A3. Does not plot data, draw graphs of functions, or make tracing worksheets.

_ 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.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 3cf6e995818e9754.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/3cf6e995818e9754/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/3cf6e995818e9754/badge.svg)](https://brick.blue/agent/3cf6e995818e9754?ref=badge)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we know
card completeness
60%

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
0

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.

Served from the same domain, which is what was measured. Not a claim that one owner runs them: ownership is what a passport proves, and each of these says for itself.
