Get info about all nodes in the Solana cluster
AI agents call get_cluster_nodes to retrieve information from Solana 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 information about cluster nodes without side effects. It is a read-only operation that queries chain data, consistent with the 'Read' category for tools that retrieve or query data without side effects. The low severity reflects the minimal risk of misuse—an agent retrieving cluster node information cannot damage systems or cause financial harm.
From the tool's definition Tool name 'get_cluster_nodes' and description 'Get info about all nodes in the Solana cluster' indicate a data retrieval operation with no modification or execution of transactions.
Attacks that exploit this kind of access
Get info about all nodes in the Solana cluster. It is categorised as a Read tool in the Solana MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Solana MCP Server MCP server in PolicyLayer and add a rule for get_cluster_nodes: 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 Solana MCP Server. Nothing to install.
get_cluster_nodes 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_cluster_nodes 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_cluster_nodes. 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_cluster_nodes is provided by the Solana MCP Server MCP server (visioneth/solana-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
