RISK

Why usdc_x402_payments_intel is rated Critical

This tool directly interfaces with USDC payment flows on the Base blockchain network, aggregating financial transaction data including settlement statistics, payment volumes, and on-chain transfer events. Even if primarily analytical, it connects to live financial infrastructure (Coinbase CDP API, Base mainnet RPC) involving real USDC transfers.

From the tool's definition Real-time analytics on x402 protocol USDC micropayments... facilitator_stats — Coinbase x402 facilitator settlement statistics (volume, count, top payees/payers)... on-chain USDC Transfer events... Coinbase CDP API

RECOMMENDED RULE

The rule that runs usdc_x402_payments_intel safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Mcp Knowledge, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For usdc_x402_payments_intel, this is the rule to start with:

usdc_x402_payments_intel Approval-gated

Any call to usdc_x402_payments_intel is blocked until a human approves it. The rest of the server keeps working.

FAQ

Questions about usdc_x402_payments_intel

What does the usdc_x402_payments_intel tool do? +

Real-time analytics on x402 protocol USDC micropayments for MCP endpoints on Base network. Unique competitive advantage: aggregates internal production telemetry (our own traffic data) with on-chain USDC Transfer events and Bazaar marketplace listings — data no external competitor can access. Four modes: (1) facilitator_stats — Coinbase x402 facilitator settlement statistics (volume, count, top payees/payers). Uses Coinbase CDP API if COINBASE_X402_API_KEY is set; falls back to Base mainnet RPC scan of USDC transfers to known facilitator addresses. (2) endpoint_intel — Per-MCP-endpoint analytics: tx count, USDC volume, unique callers, success rate, catalog size. For gapup-mcp.io endpoints: reads internal JSONL telemetry (richest data source, unique). (3) agent_caller_profile — Anonymous profile of a calling agent wallet: tx count, USDC spent, top endpoints, inferred persona (depth-seeker / bulk-scanner / generalist / researcher / explorer). Wallet anonymised via SHA-256. (4) price_radar — USDC price distribution by tool category (data_lookup / synthesis / compliance / competitive) from Bazaar + internal catalog. Returns median, P25, P75. Network: Base mainnet. USDC contract: 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913. Cache: 30 min LRU. Timeout per source: 8s. Optional env: COINBASE_X402_API_KEY (higher-fidelity facilitator stats). It is categorised as a Financial tool in the Mcp Knowledge MCP Server, which means it involves financial transactions. Block by default and require explicit approval.
