Your agent needs one go-to-market picture — the market, the companies in it, the people who decide, and what is being said about them — in a single set of tools. **What you can ask for** • "Size this market: who ranks, who gets the traffic, who advertises." • "Find the companies that fit and the people to email inside them." • "What is being said about these brands on X, Reddit and Instagram?" • "Which of these prospects is hiring for roles that imply budget?" • "Give me a competitor's keywords, backlinks and traffic mix in one pass." **How to use it** Point any MCP client at https://mcp.aisa.one/gtm/mcp and sign in with OAuth — there is no key to create or paste. 43 tools drawn from Apollo, Similarweb, Semrush, Ahrefs, X/Twitter, Instagram, Reddit and Pinterest — company enrichment and job postings, traffic and audience, keywords, backlinks and domain rating, and social search. **Why this rather than the source** The cross-source questions that usually need four tabs, answered in one conversation. **It is also a door to the rest** The same login reaches 26 sources and 580+ operations. Start anywhere here, then keep going — 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 for the pipeline side, https://mcp.aisa.one/seo/mcp for the search side, https://mcp.aisa.one/social/mcp for the conversation side.
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.
