Get essential blockchain information (block height, version)
AI agents call get_blockchain_info 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 merely queries and returns blockchain metadata without any side effects, state changes, code execution, or financial implications. It is a straightforward information retrieval operation, consistent with the Read category for tools that retrieve or query data.
From the tool's definition Tool retrieves blockchain information (block height, version) with no modification or execution capability. Description uses 'Get' which indicates a read-only query operation.
Attacks that exploit this kind of access
Get essential blockchain information (block height, version). 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 get_blockchain_info: 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.
get_blockchain_info 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 get_blockchain_info 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 get_blockchain_info. 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.
get_blockchain_info 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.
