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 three distinct read-only MCP connectors. The original `/mcp` connector covers the approved search and preview population. The companion `/mcp/catalogue` provides deterministic access to 724 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, 129 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. 724 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. Website: https://varexis.tech Developer integration: https://varexis.tech/index-connect MCP endpoint: https://varexis.tech/mcp Additional optional connector: https://varexis.tech/mcp/guidance/v1. Configure it explicitly for get_decision_guide (exact published guide IDs) and check_tool_admission_fit (bounded, source-bound declaration-review suitability). Tool schemas and setup: https://varexis.tech/varexis-index/guidance-mcp-v1.json and https://varexis.tech/index-connect#bounded-guidance. The original /mcp four-tool connector and /mcp/catalogue two-tool connector remain distinct and unchanged. The additional tools are free and read-only; they do not execute actions, verify live permissions, grant entitlements or purchase anything. Missing or unbound applicability returns evidence-required. The existing Tool Admission price and licence remain unchanged.

NordicContacts provides read-only company and decision-maker data for Finland, Sweden and Estonia through a hosted MCP server. Identify companies, count matching segments and retrieve company or contact records for B2B prospecting. Connect to https://nordiccontacts.eu/mcp using Streamable HTTP. You need a NordicContacts account with an active trial or subscription. Sign in and approve access through OAuth. For clients without OAuth support, create an API token in your NordicContacts account and configure Bearer authentication; do not share the token in a chat or public listing. Eligible new accounts receive a one-month trial with 50 shared usage units and no credit card requirement. Starter costs €49/month with 500 included units; Pro costs €79/month with 1,000 included units. Paid prices exclude VAT; applicable VAT is calculated at checkout. The trial is not a recurring free allowance. Service information, taxonomy discovery and segment-count tools do not consume balance. Record-retrieval tools, including company identification, consume the same balance as REST API retrieval and subscribed Excel exports: included units first, then prepaid top-ups. Completed retrieval calls have a one-unit minimum, including calls with no match. Exact charging is documented per tool; do not treat every MCP call as one contact. The MCP server does not create Excel files, send outreach or update CRM records. Excel downloads and Pro's HubSpot/Pipedrive integrations are separate web-application workflows. A one-time Excel purchase alone does not grant MCP access. Setup and tool reference: https://nordiccontacts.eu/agents/docs

Independent UK business software reviews, rankings and real pricing as read-only MCP tools.
Know what business software really costs before you buy it. Independent reviews of the tools UK businesses run on: phone systems, email, cloud, SEO, social media, content creation, domain names and VPNs. Both prices shown, every score explained, and a clear label on which products we use ourselves.
Find the TikTok, YouTube and Instagram creators and the blogs, review sites and roundups already promoting your competitors, with the proof, then recruit them: 32 tools for competitor rosters, graded creators, roundup placements, verified contact reveals, outreach from your own inbox, pipeline and Autopilot. OAuth 2.1 (dynamic client registration) or API key; free quick scan and sandbox keys for building agents.
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.
Source-attributed person, company, contact and entity enrichment with explicit limitations and signed evidence.
Turns text into a word cloud and a word frequency table.
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.
