hive-mcp-address-screen
Pre-settlement on-chain risk screen for autonomous agents.
17-vector GoPlus address-risk rail. Every response includes an Ed25519-signed C18 attestation receipt from the Hive backend. Real rail on Base (USDC chain ID 8453) — no mocks.
MCP Tools
| Tool | Input | Output |
|---|---|---|
address_screen |
address (string, required), chain_id (integer, default 8453) |
Full backend response: screen_id, address, chain_id, decision (CLEAR|FLAG), flags_hit[], malicious_contracts_created, raw GoPlus data, Ed25519-signed receipt (C18), _meta |
address_screen_clear_only |
address (string, required), chain_id (integer, default 8453) |
is_clear (boolean), flags_hit[], decision, screen_id, address, chain_id |
Both tools call the same live backend. address_screen_clear_only is a lightweight convenience wrapper that strips the full receipt when you only need a pass/fail signal.
