ai-mail.sh gives your AI agent its own email address for $0.05, paid with x402 (USDC on Base), with no signup.

Receive-only, no tracking, and you delete it, it's gone. Works over HTTP or MCP.

Reminders your agent creates: email, WhatsApp, SMS or call, in steps you set. Stops on acknowledge.
Your agent needs X/Twitter data — who follows a competitor, what a community is posting, who quoted that tweet, what is trending in Japan. Normally that means applying for an X developer account, passing app review, and managing a quota per endpoint. **What you can ask for** • "Who follows @stripe, and which of them are verified?" • "Pull every reply and quote on this tweet and summarise what people object to." • "List this community's moderators and its posts this week." • "What is trending in Japan right now?" • "Give me the full thread context behind this link, including the long-form article." **How to use it** Point any MCP client at https://mcp.aisa.one/twitter-api/mcp and sign in with OAuth — there is no key to create or paste. 29 read tools: users (profile, about, batch lookup by id, search, followers, verified followers, followings, follow check), tweets (timeline, latest, mentions, advanced search, replies, quotes, retweeters, thread context, articles), communities, lists, Spaces and trends. **Why this rather than the source** No developer account to apply for, no app review, no per-endpoint quota to manage. **It is also a door to the rest** The same login reaches 26 sources and 580+ operations. Ask for a handle's followers here, then ask the same agent for that brand's search traffic, its backlinks, or the people to contact — 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/social/mcp for X plus Instagram, Reddit, Pinterest and YouTube; https://mcp.aisa.one/gtm/mcp for those plus Similarweb and Apollo.
Connect your FranklyMail mailbox to AI assistants to read and search email, list folders, and prepare new messages, replies, or forwards for mandatory human review and approval.

Salesbot lets your AI assistant run careful, personal LinkedIn outreach. Find the right people (LinkedIn search, Sales Navigator, company lists, job postings), enrich their profiles and write a personal message for each of them. Nothing is sent until you approve it, or until Salesbot's AI check confirms the name, gender, company and grammar. Campaigns pace invitations and messages within daily and hourly limits that the server enforces, inside your sending hours, so your LinkedIn account stays safe. A built-in CRM keeps the pipeline, notes, tasks and companies, and e-mails go out through Smartlead, Instantly or your own mailbox. Sign in with your Salesbot account (OAuth) or use an API key. Built for a few well-chosen people at a time, not bulk blasting.
