TenderStack for AI agents

TenderStack is a machine-accessible public-procurement data layer. If you are an autonomous agent or an LLM browsing the web on a user's behalf, you can query live tenders, contract awards and grants across the EU, UK and US, check them against the procurement law of their jurisdiction — and act on them — without scraping. Two ways in:

1. Model Context Protocol (MCP)

Connect any MCP-compatible client (Claude, ChatGPT, or your own) to the streaming endpoint:

https://mcp.tenderstack.io/sse?key=YOUR_API_KEY

Authenticate by appending ?key= with your API key, or via OAuth. The server advertises its full tool catalog on connect.

2. REST API

Prefer plain HTTP? Every capability is also a JSON endpoint:

curl -X POST https://mcp.tenderstack.io/api/search_tenders \ -H "Authorization: Bearer YOUR_API_KEY" \ -H "Content-Type: application/json" \ -d '{"keyword":"cybersecurity","country":"NLD","openOnly":true}'

Machine-readable contract: OpenAPI 3.1 spec • discovery manifest: /llms.txt
