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.

Zoopla MCP server for ChatGPT, Claude and any AI agent: list my listings, update listing, reply to lead and get listing stats in your own Zoopla account. Cotlet works in the account through your Cloud Browser, a real Chrome where you sign in to Zoopla yourself; Cotlet does not store your password and you need no Zoopla API key. About the official Zoopla API: Zoopla has no public API (checked 11 Oct 2026): its developer docs say the listings API is no longer publicly available.

Setup and FAQ: https://cotlet.dev/integrations/zoopla-api-mcp-server
Property Finder MCP server for ChatGPT, Claude and any AI agent: publish listing, unpublish listing, list leads, update agent and get listing stats in your own Property Finder account.

About the official Property Finder API: Property Finder has an API, but only for software partners it approves through the PF Developer Network, not for brokers directly (checked 11 Oct 2026). Partners pass a business review and a security and compliance audit, and each PF Expert client then chooses to authorize them. Setup and FAQ: https://cotlet.dev/integrations/property-finder-api-mcp-server

About the official EstimateOne API: EstimateOne has an External API, but it is not self-service and it is read-only (checked 6 Nov 2026). E1 gives it to partner software per customer, and today it returns one thing: Speci-finder matches for a supplier account. Setup and FAQ: https://cotlet.dev/integrations/estimateone-api-mcp-server

About the official Yardi API: Yardi has no self-serve API for Breeze (checked 27 Oct 2026). Data access goes through the Yardi Interfaces Program, a paid, per-interface license for approved software vendors, and Yardi's own MCP connector for Claude is part of Virtuoso Enterprise, which needs Yardi Voyager rather than Breeze. Setup and FAQ: https://cotlet.dev/integrations/yardi-api-mcp-server

About the official SnelStart API: Yes, but it is gated (checked 14 Oct 2026).

Setup and FAQ: https://cotlet.dev/integrations/snelstart-api-mcp-server

Products, orders, customers and subscribers have no endpoints; new sales, refunds and subscription changes only arrive as 4 webhook events. Setup and FAQ: https://cotlet.dev/integrations/payhip-api-mcp-server

About the official Immobiliare.it API: Immobiliare.it has no public API for listings, messages or visit requests (checked 11 Oct 2026).

About the official Dentrix Ascend API: Dentrix Ascend has an API, but only for software vendors approved into the Henry Schein One API Exchange, not for a practice that wants to connect its own AI agent (checked 27 Oct 2026). Henry Schein One announced an MCP layer inside Dentrix Ascend on 28 Apr 2026: an Ask preview for questions in plain language, pre-built agents for select customers and a Build layer with no published date or developer docs. Setup and FAQ: https://cotlet.dev/integrations/dentrix-ascend-api-mcp-server
