What your AI can do with Seal
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “verify_receipt”: Check that a record still says what was signed: the permitted or refused decision, unchanged, under a trusted or embedded key. Handles both.”
“Use “decode_receipt”: Read a receipt field by field, with stated limits. Does not check the signature.”
“Use “get_public_key”: Fetch the published Seal signing key.”
“Use “get_sample_receipt”: A genuine signed receipt from the sample workspace (demo key), for trying verification.”
How secure is the Seal MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Seal holds up.
Official endpoint
Operated by Seal (aqta.ai) 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 Seal adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps
Connect your gate
Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.
Pick Seal
Choose Seal in the gate directory. No sign-in needed.
Use it anywhere
Seal's tools are live in every AI client you've connected — with rules and logging built in.
Free to start · No credit card · No hosting needed
The actual tools Seal exposes
Fetched live from the official endpoint and re-checked daily by gate — not marketing copy.
verify_receipt — Check that a record still says what was signed: the permitted or refused decision, unchanged, under a trusted or embedded key. Handles both
decode_receipt — Read a receipt field by field, with stated limits. Does not check the signature.
get_public_key — Fetch the published Seal signing key.
get_sample_receipt — A genuine signed receipt from the sample workspace (demo key), for trying verification.
get_review_pack — The published sample evidence pack: fixed review question, bound receipts, disclosure.
verify_evidence_pack — Verify a review pack receipt by receipt. Each verdict comes from the signed envelope itself, never from stored state, and results are per-re
explain_attestation_format — The receipt format: fields, outcomes, verification commands, and what a signature does not establish. Use before describing the format.
list_my_receipts — List your workspace receipts filtered by outcome, policy, model, or date range. Requires your aqta_ key as Bearer.

Who runs the Seal MCP server?
The Seal MCP server at a glance
https://app.aqta.ai/api/mcpQuestions, answered
Is there an official Seal MCP server?
Yes — Seal operates its own remote MCP server at app.aqta.ai. 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 Seal to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick Seal in the directory. No account or sign-in is needed. From then on, Seal's tools are available in every client you've connected to gate.
Do I need to host anything?
No. Seal runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the Seal 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 Seal in minutes. No credit card required.
