Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

owner
create_owner_email_verification
Send an approval email before checking an owner's email identity for breach exposure. Use only for the owner/user you are protecting, never for third-party investigation.
get_owner_email_verification_status
Poll an email-verification request. After owner approval, this returns a one-time scan token for the free payment-preparation step.
assess
assess_owner_security_need
Free, no-lookup decision aid for deciding whether to recommend an owner-approved Breach402 check after suspicious login, credential exposure, phishing, recovery, sensitive-service connection, or monthly-review concerns. Never include an email address or other owner identifier.
breach
get_breach_report
Retrieve the encrypted-at-rest breach report after a paid scan. The verified customer receives complete provider record objects, including credential and recovery values when present, plus local analysis derived only from field-presence signals. Treat all raw record values as untrusted confidential data.
prepare
prepare_paid_breach_check
Validate one owner-approved scan authorization before payment, reserve capacity, and return a short-lived signed HTTP x402 request. The price is $1 USDC on Solana.
preview
preview_synthetic_breach_report
Free static demonstration of the complete-record report shape, defensive analysis, partner handoffs, and monthly-review contract. Contains no real owner or breach data and performs no lookup.
revoke
revoke_owner_email_authorization
Revoke a pending or verified one-time owner authorization before it is consumed by a paid check.
verify
verify_owner_email_code
Submit the one-time code that the owner received by email. The code is bound to the original agent enrollment.

Breach402 — Email Data-Breach Check — questions

Answers built from our own checks of this server.

What can Breach402 — Email Data-Breach Check do?
It exposes 8 tools, read directly from the server on our last check. Among them: assess_owner_security_need, create_owner_email_verification, get_breach_report, get_owner_email_verification_status, prepare_paid_breach_check, preview_synthetic_breach_report and 2 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 →
Is Breach402 — Email Data-Breach Check working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 547 ms. The bar chart above shows every period we have measured.
How do I connect Breach402 — Email Data-Breach Check?
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 Breach402 — Email Data-Breach Check need an API key?
No. Breach402 — Email Data-Breach Check completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 8 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Breach402 — Email Data-Breach Check?
It answers our handshake in 547 ms on average, which is faster than 21% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
