SignSimple is a free, unlimited e-signature service. Use send_for_signature to email a PDF to recipients for legally binding electronic signature, get_document_status to track progress, list_documents for recent sends, and list_templates for free ready-to-send legal templates. Account tools need an API key header (create one at https://signsimple.app/profile).

- Is signsimple live?
- Yes — it answered the hub's last check (checked 1h ago). It answered 99% of checks over the last 30 days.
- Is signsimple free to use?
- Partly — some of its tools are open, others need a key or payment.
- What tools does signsimple have?
- 4 tools: send_for_signature, list_templates, get_document_status, list_documents.
- Is signsimple 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.

what callers paid
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.
list_templates reads open 6h ago
List SignSimple's free, professionally drafted document templates (NDA, lease, contractor agreement, liability waiver, bill of sale, promissory note). Returns each template's info page and direct PDF URL — pass the PDF URL to send_for_signature as document_url to send one. No API key needed.
{ "type": "object", "properties": {} }arguments 4 linesget_document_status reads auth-required 6h ago
Check the status of a document previously sent for signature: overall state (sent/completed/declined/expired/voided), per-recipient progress (pending/viewed/signed), and the signed PDF download URL once complete. Requires a SignSimple API key.

List the 25 most recent documents sent from the connected SignSimple account, with status and signed-PDF URLs where complete. Requires a SignSimple API key.
{ "type": "object", "properties": {} }arguments 4 linessend_for_signature sends messages unknown never probed
Send a PDF document for legally binding electronic signature via SignSimple (free, unlimited). Provide the PDF as a fetchable URL or base64, plus recipient name(s) and email(s). Each recipient is emailed a secure signing link; signature and date fields are placed automatically unless custom fields are given. Works with the free templates from list_templates (pass their pdf URL as document_url). Requires a SignSimple API key (create one at https://signsimple.app/profile).

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.
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.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - 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. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's ide304a4a701aed79a.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/e304a4a701aed79a/claim.
Over MCP: the claim_endpoint tool.

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.
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.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
