Your agent needs what people are posting — across X, Instagram, Reddit, Pinterest and YouTube at once, not five accounts and five rate limits. **What you can ask for** • "What is being said about our brand this week on X and Reddit?" • "Find the creators posting about this category on Instagram and YouTube." • "Pull the replies and quotes on this tweet and the comments on that reel." • "What is trending in this country right now?" • "Which subreddits and hashtags keep coming up for this topic?" **How to use it** Point any MCP client at https://mcp.aisa.one/social/mcp and sign in with OAuth — there is no key to create or paste. 56 read tools across five platforms: X/Twitter (users, tweets, communities, lists, Spaces, trends), Instagram (profiles, posts, reels, highlights, transcripts), Reddit (search, subreddits, comment trees), Pinterest (pins, boards, search) and YouTube search. **Why this rather than the source** One login instead of five developer programmes, and no app review on any of them. **It is also a door to the rest** The same login reaches 26 sources and 580+ operations. Measure the conversation here, then ask the same agent for the site traffic behind it 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/twitter-api/mcp · /instagram/mcp · /reddit/mcp · /pinterest/mcp · /youtube-search/mcp for one platform at a time; https://mcp.aisa.one/gtm/mcp adds Similarweb and Apollo.

Results carry entry URLs and name the outlet each quote came fr

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 to know where a brand or a phrase is being talked about across the web — with the trend line, the sentiment and the ratings attached. **What you can ask for** • "Where is our brand cited across the web this quarter, and is that rising?" • "What is the sentiment around this phrase?" • "How do ratings for this product distribute?" • "Which categories is this topic trending in?" • "Summarise everything published about this term." **How to use it** Point any MCP client at https://mcp.aisa.one/seo-content/mcp and sign in with OAuth — there is no key to create or paste. 10 tools: content search, summary, phrase and category trends, sentiment analysis, rating distribution, plus the filters, categories, languages and locations behind them. **It is also a door to the rest** The same login reaches 26 sources and 580+ operations. Find where you are mentioned here, then ask the same agent who links to those pages — 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/seo/mcp for all of it at once — rankings, keywords, backlinks, site health and AI-answer visibility across DataForSEO, Semrush and Ahrefs.
Your agent needs a pipeline, not a list — the companies worth calling, the people who decide inside them, a way to reach those people, and the market evidence that the account is worth the call. **What you can ask for** • "Find Series-B fintech companies in Germany and the heads of marketing there, with emails." • "Enrich these 200 domains with headcount, funding and tech stack." • "Which of these accounts is hiring for roles that imply they need us?" • "How much traffic does this prospect get, and where does it come from?" • "Create the account and contact records and move this opportunity to the next stage." **How to use it** Point any MCP client at https://mcp.aisa.one/sales/mcp and sign in with OAuth — there is no key to create or paste. 79 tools: Apollo people and company search, enrichment, accounts, contacts, opportunities and stages, job postings, sequences and call activity; Similarweb traffic, audience, referrals, ad spend and competitors; plus creator discovery. **Why this rather than the source** Prospecting, enrichment, market sizing and the CRM writes behind one login instead of three. **It is also a door to the rest** The same login reaches 26 sources and 580+ operations. Build the list here, then ask the same agent what those companies rank for or what is being said about them — 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/apollo/mcp or https://mcp.aisa.one/similarweb/mcp for one of them alone; https://mcp.aisa.one/gtm/mcp adds the social side.
Your agent needs to know how big a website really is — traffic, where it comes from, who else the audience visits, what they pay for ads, and which rivals take the same demand. **What you can ask for** • "How much traffic does this domain get, and how has it trended?" • "Where does that traffic come from — search, referral, social, paid?" • "Who else does this audience visit, and where do we overlap?" • "What keywords send them traffic, and which landing pages receive it?" • "What do they spend on ads, and on which networks?" **How to use it** Point any MCP client at https://mcp.aisa.one/similarweb/mcp and sign in with OAuth — there is no key to create or paste. 23 tools: traffic snapshot, trend and engagement, ranking and top sites, marketing channels and referrals, keywords and landing pages, popular pages and subdomains, demographics, audience interest and overlap, deduplicated audience, ad networks, PPC spend, technologies, similar sites and SERP players. **Why this rather than the source** A competitor's numbers without asking them, and without a seat in an enterprise dashboard. **It is also a door to the rest** The same login reaches 26 sources and 580+ operations. Size the competitor here, then ask the same agent who links to them or who to contact there — 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 to turn the finding into contacts; https://mcp.aisa.one/seo/mcp for the ranking side.

Your agent needs to know what people actually search — volume, ideas, how hard the term is, and whether interest is rising or was a spike last March. **What you can ask for** • "What is the monthly volume and difficulty for these 200 keywords?" • "Give me keyword ideas around this seed, with questions people ask." • "Which keywords does this competitor rank for that we do not?" • "Is interest in this term growing, and where?" • "What does this page already rank for?" **How to use it** Point any MCP client at https://mcp.aisa.one/seo-keywords/mcp and sign in with OAuth — there is no key to create or paste. 49 tools: Google and Bing volume and suggestions, keywords for a site or a URL, clickstream volumes, Google Trends and Ads traffic estimates, plus Semrush difficulty, question keywords, broad match and paid keywords, and Similarweb's keyword and landing page sets. **Why this rather than the source** Three sources for the same number, so a suspicious volume can be checked rather than believed. **It is also a door to the rest** The same login reaches 26 sources and 580+ operations. Size the demand here, then ask the same agent who ranks for it and who links to them — without adding a second server. **What it costs** Finding and inspecting an operation is free.
