An MCP server providing 22 pay-per-call utility tools for AI agents (scrape, validate, embed, store, moderate, notify, convert, prevent loops) without accounts or API keys, using USDC payments via the x402 protocol.
Security gateway that wraps any MCP server with per-tool policies, approval gates, and optional Ed25519-signed decision receipts. Shadow mode logs every tool call without blocking; enforce mode applies block, rate-limit, and minimum-tier rules. Receipts are independently verifiable offline with no accounts needed.
MCP server exposing Verity's trust checks as tools (verify_fact, detect_injection, moderate_content, redact_pii, guard_action) that any MCP-capable agent can discover and call for fail-closed safety verification before spending or sending.
