Claude Tango connectorWhat Claude can do in your Tango account.
The Claude Tango connector exposes 4 tools: 4 read, 0 write. None is left undocumented, and none sends anything. Below: what Claude can dig out of US federal contracting data, where the numbers mislead, and who controls access.

What changes for a capture or bid team
Tango, published by MakeGov, packages US federal procurement data (awards, vehicles, bid protests, open opportunities on SAM.gov, agency forecasts) so an assistant can query it. With the connector plugged in, you ask Claude a question in plain English and it runs the searches itself, then reads the records back to you instead of making you click through filters.
Size up a competitor before a bid. You type a vendor name. resolve turns that string into the identifier Tango uses, and get_details pulls the full record, enriched with related data when Claude asks for it.
Build this week's pipeline list. search_opportunities filters open notices and agency forecasts by agency, NAICS code, set-aside type or response deadline, so a BD lead gets a shortlist without opening SAM.gov.
Scan who wins what. search covers 13 record types, filtered by vendor, agency or dates among other criteria, and can attach a quick statistical profile of the matches.
Now the part the directory sheet leaves out. That profile is computed on 250 records at most, so its total is a sample, never a market size. Tango's own docs announce a fifth tool that the directory sheet does not list. And nothing runs on its own: no tool fires when a new notice is posted. Watching for new bids in the background is a job for an automation tool, which is a different trade. The Integrations hub gathers that side of things.
The vocabulary, in one minute
Five words you will run into while plugging Tango in.
- Connector
- The link you set up once between Claude and an account you already have, so Claude can work in it while it answers you.
- Tool
- One named thing a connector lets Claude do. Claude picks the ones it needs mid-answer, and the directory sheet lists them by name.
- Authorization
- The sign-in screen of the service itself, where you hand Claude the access it will use. Granted once per person, and revocable.
- Approval
- The confirmation Claude waits for before going ahead with something that changes an account, shown in the chat when it matters.
- MCP
- The shared standard connectors are built on: it is what lets an assistant like Claude talk to an outside service such as Tango.
Plug Tango into Claude in three steps
- 01
Find Tango in Claude
In Claude's settings, open Customize, then Connectors, and look for Tango in the list. On a Team or Enterprise workspace, an Owner or Primary Owner has to switch the connector on before any member can sign in.
- 02
Start the connection
Click Connect on its row, then sign in to Tango in the window Tango opens itself. If the link breaks later, hit Disconnect, then plug the connector back in from the same row.
- 03
Read the authorization screen
Go through the authorization screen before you accept. It belongs to Tango, not to Claude, and it sets what the access covers. You can also pull that access back later from your account at tango.dev.
The 4 tools, sorted by what they do
Tango gives Claude 4 tools: 4 that read your account, 0 that change something in it.
All four consult data. Tool names stay exactly as Claude shows them, in English.

What Claude reads (4)
4 toolsFour tools that look up federal contracting records without changing anything.
resolve
Turns a loose string, like a company name, an agency or a NAICS code, into the matching Tango identifiers with a short preview of each. It is the entry point the other tools build on.
search
Queries 13 record types, filtered by vendor, agency, NAICS, PSC, dates or keyword. On request it adds a statistical profile of the matches.
search_opportunities
Looks through open opportunities and agency forecasts, narrowed by agency, NAICS, PSC, set-aside type, response deadline, notice type or keyword. You get a list to triage, not a single record.
get_details
Fetches the full detail of one item, by ID and type, once a search or a resolve has surfaced it. An optional switch enriches the answer with related data.
What Claude asks before it acts
By default, Claude stops and asks for your go-ahead before each action it takes on an account in your place. The request shows up in the conversation, right when it matters.
With Tango, the directory sheet only exposes reading, so that prompt rarely comes into play. The rest still counts. On a Team or Enterprise workspace, owners decide whether a member can let some actions through without being asked every time. They can also cap what a connector may do for the whole organization, keeping reads and closing writes for instance, and nobody overrides that from their own account. Finally, Claude works with your rights and nothing more: data your Tango account cannot reach stays out of reach.
Which plans it works on
Out of 819 sheets in the official directory, not one displays plan-by-plan availability. The answer, connector by connector, is published nowhere. That gap is real.
The general rule is published: remote connectors are open to all users on Claude, Cowork, Claude Desktop and mobile. On Team and Enterprise, an Owner or Primary Owner switches the connector on for the organization before each member can connect. For the up-to-date state of this one, check Tango's own sheet in the official directory.
Where this connector stops
A connector is not an automation. Claude calls these tools while it answers you: nothing starts when a new notice goes live or a deadline gets close.
By default the sheet only exposes reading, and that is an observed floor, not a promise: an admin can open actions no public sheet shows. The partner badge is not a security audit either, and Anthropic says so on every sheet: it does not choose the tools a publisher exposes and does not vouch for how they behave. Everything on this page comes from MakeGov's own documentation, since neither Claude's help center nor Anthropic's developer docs cover Tango. For other sheets built the same way, see the Claude airtable connector.
