email-spam-tester
Registry code: 46fff66087538f83
Test an email before sending it. Call get_test_address, have the draft sent to the address it returns (with include_placement, to every recipient it lists, with the marker in the subject), then call wait_for_report with the slug. Fix what it reports, then test again with a fresh address. Scores are comparable between runs.

Calls placed through this hub's router, from its own receipts. Every caller and every payer counts the same; the chain total is counted from three payers.

what callers paid
Access was read off the card rather than seen on the wire: inferred: the handshake, the tool list and a call without arguments went through with no key and no payment asked; no tool was run
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.
get_test_address changes data unknown never probed
Reserve a single-use address to send a draft email to, for a full check. Returns the address and the URL its report will appear at. The address accepts exactly one message and expires after an hour. The email has to be sent by the person, from the platform or mailbox they really send from: half the checks read what that platform adds. The report covers 42 checks (SPF, DKIM, DMARC, reverse DNS, TLS, blocklists, content, links, the Gmail and Yahoo bulk-sender rules) and a plan of what to fix. lang is decided now because the message arrives minutes later over SMTP, which carries no hint of who is waiting for it. What wait_for_report returns quotes check lines in English whatever it is set to; the person following report_url sees their own language.
{ "type": "object", "title": "get_test_addressArguments", "properties": { "lang": { "anyOf": [ { "type": "string" }, { "type": "null" } ], "title": "Lang", "default": null, "description": "ISO code of the language the report and the fix plan are written in for the person who opens the report page, for example \"en\", \"de\" or \"pt-BR\". Defaults to the language of the conversation. Unknown codes fall back to English." }, "include_placement": { "type": "boolean", "title": "Include Placement", "default": false, "description": "Also check which folder (inbox, spam, promotions) the email lands in at different mailbox providers, from the same send. The email then goes to a list of recipients instead of one address and needs a marker in the subject; both come back. Some provider inboxes are public test inboxes: the subject, the sender name and the folder are shown on a public web page, so it suits messages that are not confidential." } } }arguments 25 linesget_message_source reads unknown 5h ago
The message exactly as it was received: headers, both bodies, source. Useful when a finding points at a header and the agent needs to see what it actually sent rather than what it believes it sent. The message is kept for an hour after it arrives and then deleted; within that hour anyone with the slug can read it. After that only the report remains.
{ "type": "object", "title": "get_message_sourceArguments", "required": [ "slug" ], "properties": { "slug": { "type": "string", "title": "Slug", "description": "The slug of a test whose message has already arrived." } } }arguments 14 linesget_report reads unknown 5h ago
Read a report by its slug without waiting, with provider placement so far. The report stays at its link for good and anyone with the link can read it: the checks, the score, the fix plan, and the subject and sender of the email.
{ "type": "object", "title": "get_reportArguments", "required": [ "slug" ], "properties": { "slug": { "type": "string", "title": "Slug", "description": "The slug of a test, the last part of the report URL." } } }arguments 14 lineswait_for_report reads unknown 5h ago
Wait until the message arrives and has been analysed, then summarise it. Call it after the email has been sent to the address from get_test_address. Blocks rather than returning "not ready yet": an agent told to poll writes a sleep loop and usually gives up before the analysis finishes. Provider placement keeps filling in for up to 30 minutes after the report; get_report reads the latest.
{ "type": "object", "title": "wait_for_reportArguments", "required": [ "slug" ], "properties": { "slug": { "type": "string", "title": "Slug", "description": "The slug get_test_address returned, the last part of the report URL." }, "timeout_seconds": { "type": "integer", "title": "Timeout Seconds", "default": 150, "maximum": 600, "minimum": 5, "description": "How long to block waiting for the message and its analysis, in seconds. The checks are ready in well under a minute; the fix plan takes about another one. Past this the tool returns what it has." } } }arguments 22 lines
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 id46fff66087538f83.

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.
