What your AI can do with Assinafy
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “assinafy_check_fields”: Prepare template values or collect field placements. list finds reusable definitions; get inspects one field; validate checks values without.”
“Use “assinafy_delete_document”: Delete a document only when the user's instruction explicitly authorizes deletion. Inspect its current state first; Assinafy enforces which.”
“Use “assinafy_download_document”: Retrieve bytes only when needed. artifact downloads original (default), certificated, certificate-page, pades or bundle; wait for certificat.”
“Use “assinafy_find_documents”: Find a document or check signing progress. Use list to search; get to inspect status, assignment, signer IDs and artifacts; activities for t.”
How secure is the Assinafy MCP server?

Official endpoint
Operated by Assinafy (com.br) at its documented MCP endpoint — not a third-party mirror or community re-host.
No sign-in needed
This server only exposes public data — no account and no credentials are involved when you connect.
Scanned before it goes live
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
Watched for drift
If Assinafy adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.

The Assinafy MCP server at a glance
https://mcp.assinafy.com.br/mcpQuestions, answered
Is there an official Assinafy MCP server?
Yes — Assinafy operates its own remote MCP server at mcp.assinafy.com.br. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.
How do I connect Assinafy to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick Assinafy in the directory. No account or sign-in is needed. From then on, Assinafy's tools are available in every client you've connected to gate.
Do I need to host anything?
No. Assinafy runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the Assinafy MCP server safe to connect?
It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
Is it free?
Yes — you can get started with gate for free and connect Assinafy in minutes. No credit card required.
