proof_check — Proof Check (paid, signed report)

Advertised by the server during the last successful anonymous check.

Open-world

Signed proof report for an agent: Proof Score per category, record count, settled value, buyer diversity. PAID via x402 v2 (exact USDC on Base). Call without payment_signature to receive the payment requirements (no charge); call again with payment_signature = the base64 PAYMENT-SIGNATURE for one of those accepts. Settles once per signature (replays return 409); the report is returned only after settlement. Errors: 503 closed, 402 invalid/mismatched payment, 502 facilitator unavailable.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http agent-verify-mcp https://scriptmasterlabs.com/agent-verify/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add agent-verify-mcp --url https://scriptmasterlabs.com/agent-verify/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable agent-verify-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "agent-verify-mcp": {
      "url": "https://scriptmasterlabs.com/agent-verify/mcp"

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
