VAREXIS-INDEX — Source-Linked Evidence & Verification Tools for AI Agents VAREXIS-INDEX provides free, source-linked evidence for agent decisions through twelve focused guides and two distinct read-only MCP connectors. The original `/mcp` connector covers the approved search and preview population. The companion `/mcp/catalogue` provides deterministic access to 696 additional records by category and exact identifier. Configure both through the existing quickstart: https://varexis.tech/index-connect#quickstart Four optional one-time local checkers analyse supported customer-supplied declarations: Tool Admission £49, Audit Coverage £79, Data Exit £79 and Transaction Integrity £149, excluding VAT. These products do not independently inspect live systems, enforce permissions, establish payment settlement, verify deletion or certify compliance. Twelve free decision guides: https://varexis.tech/index-packs#free-decision-guides Read-only agent enquiry navigation (12 guides, 99 referenced records): https://varexis.tech/varexis-index/agent-entry.json Select a candidate guide, then follow the exact connector tool and identifier in the canonical manifest. Navigation does not establish applicability, a customer outcome or authority to act. Evaluate agent permissions, delegated authority, audit provenance, payment integrity, data retention and software supply-chain evidence before relying on documented claims. **FREE MCP CONNECTOR** Endpoint: https://varexis.tech/mcp Connect using Streamable HTTP. No authentication is required for public evidence discovery. Four free, read-only tools: - find_evidence_questions — Find existing reviewed evidence questions and matching routes. - preview_evidence_answer — Retrieve complete supported public answers, sources, limitations and snapshot hashes. - find_package_advisories — Find source-bound software advisory records. - get_index_access_options — Discover available services, pricing, licensing and purchasing requirements. Public MCP cannot execute actions, inspect private systems or authorise deployment. Developer quickstart: https://varexis.tech/index-connect **LICENSED VERIFICATION TOOLS** Four separately licensed, reusable local executables: **1. Agent Tool Admission & Permission Control — £49** Compare declared tool actions, resources, recipients and permissions across supported GitHub, Playwright, Notion and Slack integrations. Identify authority conflicts, missing verification and permission changes before human review. **2. Agent Audit & Evidence Coverage — £79** Reconcile declared identities, authorisations, actions and outcomes. Identify missing audit events, inconsistent references and unresolved export, retention or recovery evidence. **3. Agent Data Exit & Retention Reconciler — £79** Compare declared data inventories, exports, deletions, retention conditions and residual copies. Identify missing evidence and unresolved data-custody conditions during migrations and offboarding. **4. Agent Transaction Integrity & Replay Analyzer — £149** Reconcile declared spending authority, amended transaction terms, scoped idempotency keys, retries and reported outcomes. Identify conflicting purchase attempts and unresolved payment or entitlement evidence. All four products are separately licensed for reusable internal execution. Prices are one-time, exclude applicable VAT and do not include subscriptions, hosting or future updates. Checkers analyse supplied declarations locally. They do not independently inspect production systems, execute payments, enforce permissions, certify compliance or establish financial settlement. Explore all products, representative findings and free previews: https://varexis.tech/index-packs **FREE EVIDENCE PACKS** Seven complete public evidence packs cover: - GitHub and Playwright permission boundaries. - Notion and Slack access and data handling. - Audit and export evidence coverage. - Next.js advisory source assertions. - SonarQube, Snyk and Semgrep scanner trust. - Telemetry redaction and exception handling. - GitHub release approval and artifact identity. Source reviews include documented versions, provenance, exclusions and reliance boundaries. They are not independent deployment tests or current security certifications. 696 additional reviewed records are publicly available through exact-ID HTTP catalogue links and the separate read-only https://varexis.tech/mcp/catalogue connector. They remain outside the original MCP search and preview population and paid saved retrieval. Enhanced natural-language search for these additions remains on HOLD. Public catalogue: https://varexis.tech/varexis-index.json **SAVED EVIDENCE & SUBSCRIPTIONS** - Single Request: £5 — Save a version-bound published evidence result or obtain the eligible original Agent Tool Evaluation & Integration Kit. - Evidence Receipt: £19 — Add an unsigned delivery receipt to the eligible saved result. - Research: £29/month. - Developer/API: £149/month. Prices exclude applicable VAT. Subscription eligibility, rate limits and exclusions apply. The four separately licensed verification executables are not included in these existing evidence or subscription offers. **AGENT PURCHASING & RECOVERY** VAREXIS supports hosted Stripe checkout and compatible authorised MPP/Stripe Shared Payment Token purchasing through separate payment interfaces. Agent purchases require owner spending authority for the exact VAT-inclusive quote and any necessary provider authentication. Not every agent or wallet is supported. Public MCP remains free and read-only. Payment credentials and private customer data must not be submitted to the public connector. Existing purchases should be retrieved using the original credential. Uncertain payments must be investigated and recovered through supported procedures, not automatically purchased again. Purchase or recover: https://varexis.tech/index-access Agent payment contract: https://varexis.tech/varexis-index/agent-payments.json **WHY VAREXIS?** VAREXIS combines source-linked evidence, explicit limitations, versioned deliverables and structured verification of supplied declarations. Its purpose is to help agents and developers distinguish what available evidence actually establishes from what remains uncertain, unsupported or outside authority. Free evidence discovery. Transparent product scope. Reusable local verification. Bounded reliance.

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 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.

Your agent needs company financials it can compute on — statements, ratios, earnings, estimates, filings and insider activity as structured data, not a PDF. **What you can ask for** • "Give me 8 quarters of income statement, balance sheet and cash flow for this ticker." • "What do analysts estimate for next quarter, and how did the last four surprise?" • "Find this exact line item across every filing." • "Who bought or sold as an insider in the last 90 days?" • "Screen for profitable companies under this valuation with growing revenue." **How to use it** Point any MCP client at https://mcp.aisa.one/marketpulse/mcp and sign in with OAuth — there is no key to create or paste. 21 tools: prices and snapshots, income statements, balance sheets, cash-flow statements, financial metrics and snapshots, earnings, analyst estimates, company facts, filings and filing items, line-item search, a screener, insider trades, macro interest rates, news, plus EDINET documents and filing digests for Japanese issuers. **Why this rather than the source** Statements as fields you can compute on, and a screener in the same place. **It is also a door to the rest** The same login reaches 26 sources and 580+ operations. Read the fundamentals here, then ask the same agent what social is saying about the ticker — without adding a second server. **What it costs** Finding and inspecting an operation is free.

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 the derived numbers — domain authority, what a site ranks for, related and relevant keywords, search intent, and who the real competitors are — for Google, Amazon and the app stores. **What you can ask for** • "What is this domain's authority, and how has its rank history moved?" • "Which keywords does this site rank for, and with what intent?" • "Who are this domain's organic competitors, and where do we overlap?" • "Which keywords does this Amazon product rank for?" • "Compare these two domains keyword by keyword." **How to use it** Point any MCP client at https://mcp.aisa.one/seo-labs/mcp and sign in with OAuth — there is no key to create or paste. 46 tools: ranked, related and relevant keywords, keyword ideas and intent, domain authority and rank history, competitor and intersection analysis, bulk metrics, plus the same shapes for Amazon products and Apple and Google Play apps. **Why this rather than the source** Ahrefs domain rating, Semrush rank history and DataForSEO Labs answering the same questions side by side. **It is also a door to the rest** The same login reaches 26 sources and 580+ operations.

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. 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 the link graph — who points at a competitor, what anchor text they use, what was won or lost last month, and which sites link to all of your rivals but not to you. **What you can ask for** • "Who links to my competitor and not to me?" • "What anchors point at this domain, and how spammy are the sources?" • "Which links did this site win and lose in the last 30 days?" • "Compare the referring domains of these five competitors." • "Summarise the backlink profile of these 100 domains in bulk." **How to use it** Point any MCP client at https://mcp.aisa.one/seo-backlinks/mcp and sign in with OAuth — there is no key to create or paste. 27 tools: backlinks and referring domains, anchors, new and lost links over time, domain and page intersections, referring networks, spam scores, bulk summaries for many domains at once, plus Semrush's own backlink and indexed-page sets. **Why this rather than the source** Two independent link indexes behind one account — coverage differs, and the gap is usually the interesting part. **It is also a door to the rest** The same login reaches 26 sources and 580+ operations. Find the link gap here, then ask the same agent who runs those sites and how to reach 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/seo/mcp for all of it at once — rankings, keywords, backlinks, site health and AI-answer visibility across DataForSEO, Semrush and Ahrefs.
UN FAOSTAT global food & agriculture statistics over a local SQLite mirror, via MCP.
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.

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.
