# viaNexus vAST — AI Connector viaNexus vAST publishes 6 MCP tools to Claude. Marketplace availability, tool surface, verification tier, and what Node8 measured against the live endpoint. Source: https://node8.ai/ai-connectors/finance/vianexus-vast/ --- [AI Connectors](https://node8.ai/ai-connectors/) · [Finance](https://node8.ai/ai-connectors/finance/) # viaNexus vAST Licensed institutional market data through the viaNexus marketplace Listed in Claude · 6 published tools · Verified partner [Claude connector docs](https://console.blueskyapi.com/docs/vAST#mcp) [vianexus.com](https://vianexus.com/) Overview ## What viaNexus vAST does viaNexus operates a marketplace for licensed financial data, reselling both its own datasets and those of partner providers under one contract and one interface. The material spans real time and delayed pricing, global news, fundamentals, regulatory filings, reference data and alternative datasets, normalised into consistent shapes before it is returned. The pitch is aimed at professional finance teams: entitlements are enforced per agent, so what a given connection can reach is set by the licence rather than by instructions in a prompt. Six tools are declared, a compact number next to the breadth of the catalogue, and credentials are required at the endpoint. ### Who it is for Professional finance teams and data engineers working under a viaNexus licence. ### Tool surface viaNexus gates tools/list behind authentication, consistent with entitlement checks that differ by subscriber, and the six published tools go undescribed here as a result. Availability ## Where viaNexus vAST is listed viaNexus vAST is listed in the Claude connectors directory only. viaNexus has no app under the same domain in the ChatGPT directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them. The MCP server behind a Claude connector is usually the same server a ChatGPT app would need, so the absence is a distribution decision rather than a technical one. Claude listing ## In the Claude connectors directory viaNexus vAST publishes 6 tools to Claude. That is a mid-sized surface: 28.1% of the 1,253 Claude-listed connectors expose fewer. The median Claude-listed connector filed under Finance publishes 12, so this one sits 6 tools below its bucket's median, 120th of 159. It falls in the 4-6 tools band, which holds 16.2% of the Claude directory. viaNexus vAST publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally. Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there. Publisher viaNexus Verification Verified partner (37.8% of the Claude directory) Filed under Financial Services Endpoint `https://vast.blueskyapi.com/vianexus/mcp` Documentation [Publisher setup docs](https://console.blueskyapi.com/docs/vAST#mcp) Published tools 6 · 4-6 tools band Depth rank in Finance 120 of 159 Snapshot August 2026 viaNexus vAST carries partner verification in the Claude directory, which 474 of 1,253 listings do (37.8%). That is a review step past self-publishing, not an Anthropic-built server. In the publisher's words ## How viaNexus describes it > viaNexus MCP connects to the viaNexus marketplace that includes licensed, institutional-grade financial data — including proprietary and premium partner data including real-time and delayed prices, global news, fundamentals, filings, reference data, and alternative datasets.
