Set up Sell to State for me: government tenders and contract awards from official sources in 73 countries, as MCP tools. Agent docs: https://docs.selltostate.com/llms.txt
1. Sign me in yourself. Try this first: you need me only for one approval click.
- If you can send HTTP requests: POST https://staging-app.selltostate.com/api/v1/agent/signup with JSON {"client_name": "<your app name>"}. Open verification_uri_complete from the reply in my browser if you can, else show it to me as a link. I 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://staging-app.selltostate.com/api/mcp.
- If you cannot send HTTP requests: tell me to add the MCP server https://staging-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.
3. Call whoami. If it has onboarding_required, fill its questions with what you know about my company, ask me the rest, show me all the answers and ask me for product files. Then call submit_onboarding: show me its rows with their links and offer me its next_options. Without onboarding_required: ask me what my company sells and in which countries, call plan_search, then search with its scope, q and filters, show me the 10 best open tenders, and give me app_url.
