# Tango — AI Connector Tango publishes 4 MCP tools to Claude. Marketplace availability, tool surface, verification tier, and what Node8 measured against the live endpoint. Source: https://node8.ai/ai-connectors/data-analytics/tango/ --- [AI Connectors](https://node8.ai/ai-connectors/) · [Data & Analytics](https://node8.ai/ai-connectors/data-analytics/) # Tango US federal procurement data for contracting research Listed in Claude · 4 published tools · Verified partner [Claude connector docs](https://tango.makegov.com/docs/mcp/) [makegov.com](https://makegov.com/) Overview ## What Tango does Tango, published by MakeGov, exposes United States government contracting data through an MCP endpoint. The listing describes it as competitive intelligence on federal procurement, structured for language models rather than for a reporting tool, and names procurement professionals as the intended reader rather than analysts of the market at large. The record is otherwise brief: four claimed tools, partner tier, documentation published, and credentials needed before anything responds. What the four tools divide the dataset into is not stated anywhere in the entry. ### Who it is for Capture and proposal teams pursuing federal contracts. ### Tool surface Four tools for a procurement dataset would be worth inspecting, except the endpoint returns 401 before naming any of them. Availability ## Where Tango is listed Tango is listed in the Claude connectors directory only. MakeGov Inc 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 Tango publishes 4 tools to Claude, a deliberately narrow surface; only 17.2% of the 1,253 Claude-listed connectors expose fewer. The median Claude-listed connector filed under Data & Analytics publishes 12, so this one sits 8 tools below its bucket's median, 163rd of 198. It falls in the 4-6 tools band, which holds 16.2% of the Claude directory. Tango 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 MakeGov Inc Verification Verified partner (37.8% of the Claude directory) Filed under Data & Analytics Endpoint `https://govcon.dev/mcp` Documentation [Publisher setup docs](https://tango.makegov.com/docs/mcp/) Published tools 4 · 4-6 tools band Depth rank in Data & Analytics 163 of 198 Snapshot August 2026 Tango 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 MakeGov Inc describes it > The Tango server gives AI agents access to reliable, LLM-friendly federal procurement competitive intelligence so that procurement professionals can focus on delivering on mission. Quoted from the connector's own Claude directory listing as captured in August 2026. Node8 did not write it and does not vouch for it.
