Agent View of the PolicyLayer registry record for `transfer_nft`. HTML page: https://policylayer.com/tools/chulanpro5-evm-mcp-server/transfer-nft ## Facts - Tool: `transfer_nft` - Server: EVM MCP Server (`chulanpro5/evm-mcp-server`) — https://policylayer.com/tools/chulanpro5-evm-mcp-server.md - Homepage: https://github.com/chulanpro5/evm-mcp-server - Risk category: Financial (Critical risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Approval-gated ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "transfer_nft", "arguments": {} } } ``` ## Why transfer_nft is rated Critical Transferring an NFT is a financial operation as it moves a potentially valuable digital asset (NFT) between addresses on the blockchain. This is irreversible once confirmed on-chain, and misuse could result in permanent loss of valuable assets. The requirement for a private key signing makes this a real, committed blockchain transaction with financial consequences. From the tool's own definition: "Transfer an NFT (ERC721 token) from one address to another. Requires the private key of the current owner for signing the transaction." ## Use case AI agents use transfer_nft to commit financial operations through EVM MCP Server, usually the final step of a payment, billing, or trading workflow. A call moves real money. ## Recommended policy (PolicyLayer) Verdict: **Approval-gated**.
