A tool that vanishes takes a piece of your agent with it, and the change arrives silently. Watch this server and every such change lands in your inbox.

inbox

inbox_clearance_buy

Inbox Clearance license: $222.00 once, use it forever — no subscription, no contract. Your own agent runs the clearance pass on your own Gmail; we never hold your credentials and never see your mail.

Open an Inbox Clearance pass under your perpetual license (inbox_clearance_buy, $222 once).

Free — the license key is the gate; we never hold your credentials and never see your mail.

inbox_clearance_record_pass

Record element and setting states into an open Inbox Clearance pass: before/after values your agent read live, each confirmed, unverified with its reason, or failed with its reason. Unknown ids are refused — password, 2FA, passkey and recovery changes are excluded by construction. Free under the perpetual license.

inbox_clearance_report

Close an Inbox Clearance pass and mint its signed before/after report: per-element states and hashes in a signed Outcome Receipt ($0.00 charged under the perpetual license).

Agent Embassy — questions

Answers built from our own checks of this server.

What can Agent Embassy do?

It exposes 33 tools, read directly from the server on our last check. Among them: agentid_issue, agentid_renew, agentid_revoke, agentid_verify, attest_document, attest_work and 27 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is Agent Embassy mostly used for?

Its tools cluster around agentid, compute and inbox. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is Agent Embassy working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 367 ms. The bar chart above shows every period we have measured.

Did Agent Embassy ever remove tools?

Yes. notarize, contribute, verified_check, assurance_check and 7 more are no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.

Is Agent Embassy still maintained?

The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.

How do I connect Agent Embassy?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Agent Embassy need an API key?

No. Agent Embassy completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 33 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Agent Embassy?

It answers our handshake in 367 ms on average, which is faster than 36% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
