Paw to paw. Shelter pets, one question away. Ask in plain words, in any of ten languages ("Use Petnecto to find me a calm older dog near Seattle that is good with cats") and get real adoptable pets near the place you name, with photos, ages, sizes, what each rescue says about them, and exactly how to reach the rescue. Listings come from open public data that shelters and governments publish (Taiwan's national adoption listings, King County WA and Montgomery County MD in the US, Zaragoza and Vienna in Europe), credited in every answer. Adoption always happens through the rescue: Petnecto takes no payments, applications or personal details, and needs no account.

Your agent needs a mailbox of its own — to receive, thread, draft and send, with attachments, without borrowing your personal inbox or your company's SMTP. **What you can ask for** • "Create an inbox for this agent and tell me its address." • "Read the new messages in this thread and draft a reply." • "Send this message with the attachment and wait for the response." • "Search this inbox for everything from that domain." • "Show delivery metrics and the events on this inbox." **How to use it** Point any MCP client at https://mcp.aisa.one/mail/mcp and sign in with OAuth — there is no key to create or paste. 49 tools: create and delete inboxes, list and read messages, raw message bodies, attachments, threads, drafts and draft attachments, send and reply, message search, inbox events, metrics, and list entries — reads and writes. **Why this rather than the source** A real inbox an agent owns, rather than an SMTP credential it borrows from a human. **It is also a door to the rest** The same login reaches 26 sources and 580+ operations. Find the contact elsewhere in the catalogue, then write to them from here — without adding a second server. **What it costs** Finding and inspecting an operation is free. Running one is billed per call at API prices, with no seat and no monthly minimum, and every call takes max_price_usd so an agent cannot overspend by accident. **Where else it reaches** https://mcp.aisa.one/sales/mcp finds the person to write to.
