List known famous contracts with their names and script hashes for the active network(s)
AI agents call list_famous_contracts to retrieve information from Neo N3 MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays information about pre-existing smart contracts (their names and script hashes) from the blockchain. It performs a read-only operation with no side effects—it does not create, modify, delete, execute, or transfer assets. The action is purely informational, making it a Read category tool with low severity.

Attacks that exploit this kind of access
List known famous contracts with their names and script hashes for the active network(s). It is categorised as a Read tool in the Neo N3 MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Neo N3 MCP Server MCP server in PolicyLayer and add a rule for list_famous_contracts: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Neo N3 MCP Server. Nothing to install.
list_famous_contracts is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_famous_contracts rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for list_famous_contracts. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
list_famous_contracts is provided by the Neo N3 MCP Server MCP server (r3e-network/neo-n3-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
