Who it is for
Capture and proposal teams pursuing federal contracts.
Overview
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.
Capture and proposal teams pursuing federal contracts.
Four tools for a procurement dataset would be worth inspecting, except the endpoint returns 401 before naming any of them.
Availability
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
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.
https://govcon.dev/mcp 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
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.

This is an independent catalogue entry compiled by Node8 from Tango's public marketplace listing as it stood in August 2026. Listing facts come from the marketplaces; the comparisons against the rest of the directory and any live-endpoint measurements are Node8's. Node8 is not affiliated with MakeGov Inc, and inclusion here is not an endorsement.
Node8 builds MCP servers end to end: deciding which tools are worth exposing, the authentication and permission model, the review submissions, and the onboarding that gets them used. One server serves ChatGPT, Claude, and Microsoft Copilot.
