Email marketing: campaigns, audiences, contacts, segments, templates and reports.
Your agent needs creators who actually fit — starting from one profile you already like, or from a brief — and then a way to reach them. **What you can ask for** • "Find creators similar to this profile, in this country." • "Who else makes content like this account, with a comparable audience?" • "Look up the contact email for this creator." • "Build a shortlist for this brief and give me the emails." **How to use it** Point any MCP client at https://mcp.aisa.one/creator-discovery/mcp and sign in with OAuth — there is no key to create or paste. 2 tools: similar-creator lookup from a seed profile or a brief, and an email lookup for a creator. **Why this rather than the source** Similarity from a profile you already trust, rather than a filter over a follower-count database. **It is also a door to the rest** The same login reaches 26 sources and 580+ operations. Shortlist the creators here, then ask the same agent for their posting history on Instagram or X — 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 what those creators actually post; https://mcp.aisa.one/sales/mcp for the rest of the outreach.

Your agent needs B2B contacts and the pipeline objects around them — find the company, find the person, get the email, then write it back where your team works. **What you can ask for** • "Find heads of engineering at Series-B SaaS companies in the Nordics, with emails." • "Enrich these companies with headcount, industry and funding." • "What roles is this company hiring for right now?" • "Create an account and a contact, then log this opportunity." • "Search our sequences for messages sent to this domain." **How to use it** Point any MCP client at https://mcp.aisa.one/apollo/mcp and sign in with OAuth — there is no key to create or paste. 54 tools: people and organisation search and enrichment, job postings, accounts, contacts, opportunities and their stages, custom fields, labels, notes, users, email accounts, sequence messages and phone-call search — reads and writes. **Why this rather than the source** The full object model, not just a search endpoint, so an agent can finish the job rather than hand you a CSV. **It is also a door to the rest** The same login reaches 26 sources and 580+ operations. Find the person here, then ask the same agent what their company's traffic looks like or what they rank for — 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 adds Similarweb and creator discovery around it.
Your agent needs the whole search picture — what you rank for, who outranks you, who links to them, what is broken on the site, and whether ChatGPT names you at all. Normally that is three SEO vendors and three subscriptions. **What you can ask for** • "What does this domain rank for, and which competitors take the same keywords?" • "Who links to my competitor and not to me?" • "Crawl this site and list the pages with broken tags or duplicate content." • "Does Perplexity cite us when asked about this category?" • "How hard is this keyword, and what does the SERP look like today?" **How to use it** Point any MCP client at https://mcp.aisa.one/seo/mcp and sign in with OAuth — there is no key to create or paste. 60 tools spanning DataForSEO, Semrush and Ahrefs: SERPs, keywords and difficulty, backlinks and referring domains, on-page crawling, domain authority, and answers from ChatGPT, Claude, Gemini and Perplexity. **Why this rather than the source** Three indexes behind one account, so you can cross-check a number instead of trusting one vendor's version of it. **It is also a door to the rest** The same login reaches 26 sources and 580+ operations. Check the ranking here, then ask the same agent for that competitor's traffic mix, its ad spend, or the person to email — 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** Narrower endpoints: https://mcp.aisa.one/seo-serp/mcp · /seo-keywords/mcp · /seo-backlinks/mcp · /seo-onpage/mcp · /seo-labs/mcp · /seo-ai-visibility/mcp · /seo-content/mcp · /seo-domains/mcp · /seo-business/mcp · /seo-merchant/mcp · /seo-apps/mcp · /seo-serp-other-engines/mcp
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.
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.
