1. Sign me in yourself. Try this first: you need me only for one approval click.
- If you can send HTTP requests: POST https://app.selltostate.com/api/v1/agent/signup with JSON {"client_name": "<your app name>"}. Show me verification_uri_complete from the reply as a link. I open it, sign up free with Google or email, and approve the code. Every "interval" seconds, POST token_endpoint with {"device_code": "<device_code>"} until the reply has access_token. Send access_token in the x-api-key header to the MCP server https://app.selltostate.com/api/mcp.
- If you cannot send HTTP requests: tell me to add the MCP server https://app.selltostate.com/api/mcp in this app. Its sign-in page also creates the free account.

2. The tools are free to connect. A free account gets plan_search 3 times a day and search for 2 different searches a day: titles, buyers, status and dates. Amounts, winners and notice links need a plan. Call whoami to see my plan. Read the skill at https://www.selltostate.com/skills/selltostate-government-contracts-database/SKILL.md.
3. Using the Sell to State database, give me a brief on <buyer name>: total spend, top suppliers, top sectors, contracts by year and its open tenders.

# Buyers, suppliers and awards database (Sell to State)

## Access

1. MCP: the server https://app.selltostate.com/api/mcp (OAuth, or the x-api-key of the agent sign-in: POST https://app.selltostate.com/api/v1/agent/signup, the user approves one code). Call `whoami`. `active` false is a free account: `plan_search` and `search` only, 1-2 searches a day.
2. REST: https://app.selltostate.com/api/v1 with the header `x-api-key`. Read the key from `STS_API_KEY` and never print it.
3. No plan yet: the user picks a plan at https://app.selltostate.com/plans, or you run the agent signup in "Get access" of https://www.selltostate.com/skills/selltostate/SKILL.md. The user pays in the browser.

## Task

Using the Sell to State database, give me a brief on <buyer name>: total spend, top suppliers, top sectors, contracts by year and its open tenders.

Ask the user for each value in <angle brackets> before the first call.

## Steps

1. Find the buyer: MCP `search` with `scope=buyers` and `q=<buyer name>`. Note its `slug` and `country`.
2. Get the brief: MCP `get_buyer` / `get_buyer_detail`, or `GET https://app.selltostate.com/api/v1/buyers/{slug}?country=<slug>`: spend, top suppliers, sectors, contracts by year.
3. Get its open tenders: MCP `search` with `scope=tenders`, `q=<buyer name>`, `country`, `accepts_bids=true`.
4. For a sector view: MCP `list_sectors` and `get_sector`. For lists: `list_buyers`, `list_suppliers`.
5. Give totals per currency and `source_url` for each award or tender.

## Rules

- Give `source_url` (the official notice) for each tender and award. The user reads the documents and bids on the official portal.
- Amounts are in the source currency. Do not add amounts in different currencies.
- The data shows awards, not bids. Do not say that a company lost a tender.
- On a 402, show the message and the link to the user, then stop. On a 429, wait `Retry-After` seconds.
- Credit the data: "Data: Sell to State (selltostate.com)".
