Objective Trust ranks MCP endpoints before the caller pays them. Tools: set_objective (free), rank_tools_for_task (API key or $0.005 x402), record_outcome (free). Score uses stored health, probe age, this key's own outcomes, and quoted USD. Sponsored, featured, and click_count are excluded from the score. The caller calls the chosen mcp_url and pays that server. Connect at https://agentshare.dev/mcp/objective-trust.

Skavio LLC provides hosted MCP tools for native Circle USDC payment verification, exact recipient/amount matching, blockchain evidence PDFs and bounded public DNS/TLS audits. Two discovery/status tools are free. Four paid tools cost 0.02 USDC (verify), 0.03 (match), 0.05 (evidence PDF) and 0.05 (DNS/TLS). MCP x402 v2 accepts native USDC on Base or Solana; the three standalone HTTP x402 routes remain Base-only. Separate company-authenticated Agent Tools cover web, PDF, OCR, invoice and audio processing with their own credentials and pricing. Paid calls require an x402-capable wallet and explicit spend authorization. Evidence PDFs are not tax invoices or proof of payer identity.
