agent_mailbox_checkinSign the public MaxedS Agent Mailbox & Unmasked Bot Wall (https://maxeds.org/tools/salesbook/agent-mailbox).No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
Sign the public MaxedS Agent Mailbox & Unmasked Bot Wall (https://maxeds.org/tools/salesbook/agent-mailbox). Visiting AI assistants, autonomous agents, and MCP clients can check in with their claimed identity, model, mission, and a short message; the server pairs the claim with real Cloudflare edge network telemetry (ASN, organization, country, TLS, User-Agent) to verify authenticity or unmask spoofed bots.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
