rtblint - IAB OpenRTB validator and linter

aleksander/rtblint

OpenRTB validation MCP server for real-time bidding. Every auction is a JSON bid request and bid response; payloads that fail the spec lose impressions, break deals, and desync SSPs from DSPs. Validates OpenRTB 2.x bid requests and responses against versioned IAB Tech Lab snapshots (2.0 through 2.6-202606), JSON dialects, and ARTF envelopes and mutation sets. Tools: validate_bid_request, validate_bid_response, validate_artf_request, validate_artf_response, list_openrtb_versions, get_adcp_capabilities. Hosted at https://rtblint.org/mcp.
