MCP server (Streamable HTTP)

JSON-RPC 2.0 MCP endpoint, protocol versions 2026-07-28 and 2025-11-25. Free tools: shadowgraph_market_recap, shadowgraph_company_filings, shadowgraph_eu_tenders, shadowgraph_free_preview, shadowgraph_service_info. Paid tools ($0.50–$5.00) use the MPP MCP binding: an unpaid tools/call returns JSON-RPC error -32042 with error.data.challenges; retry with params._meta["org.paymentauth/credential"]; the receipt is returned in result._meta["org.paymentauth/receipt"]. For 2026-07-28 send MCP-Protocol-Version, Mcp-Method and (for tools/call) Mcp-Name headers.
