Description, as the server wrote it
Native ETH balance of a Base mainnet address, incl. balance_usd (ETH price cross-call — no price oracle on ETH-only competitors), via multi-provider JSON-RPC. Cost: $0.005 USDC per call via x402.

Description, as the server wrote it
Token security check (honeypot detector + rug-pull risk score) for a Base ERC-20 in one call, decision-grade trade-safety verdict: SAFE | CAUTION | AVOID plus risk_score (0-100) and reasons, bundling honeypot/sellability simulation, owner-renounced + mint/pause/blacklist/fee-setter/upgradeable-proxy checks, token symbol/name/decimals, and Uniswap v3 WETH-pool liquidity (USD). Replaces many RPC calls and prevents a bad trade. Cost: $0.005 USDC per call via the shared MCP payment gate (the direct HTTP endpoint GET /chain/token-report is $0.01 — MCP tools/call is gated at a flat $0.005 per request).

Description, as the server wrote it
Security-audit a target MCP server for prompt-injection / tool-poisoning.

Description, as the server wrote it
FREE preview scan of a target MCP server for tool-poisoning / prompt-injection. Returns issue count, severity breakdown, risk score, and verdict (clear/review/block) — but NOT which tools or the evidence. Use this to check any MCP server (including your own) at no cost; if issues are found, call the paid scan_mcp_server for the itemized findings + remediation. No payment required.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
