Used to look up account info by public key (32 byte base58 encoded address)
AI agents call getAccountInfo to retrieve information from Solana Model Context Protocol (MCP) Demo without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves account information from the Solana blockchain using a public key as input. This is a read-only operation that has no side effects, does not modify state, and does not execute code or trigger external operations. The public key is not sensitive—it is by definition public on the blockchain. Severity is low because misuse would only expose information that is already publicly available on the ledger.
From the tool's definition Tool name is 'getAccountInfo' and description states it is 'Used to look up account info by public key'. This is a query/retrieval operation with no modification or execution capabilities.
Documented attack patterns abuse exactly the kind of access getAccountInfo gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Solana Model Context Protocol (MCP) Demo, and nothing reaches the server without passing your rules. This is the rule we recommend for getAccountInfo:
{
"version": "1",
"default": "deny",
"tools": {
"getAccountInfo": {}
}
}getAccountInfo is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Used to look up account info by public key (32 byte base58 encoded address). It is categorised as a Read tool in the Solana Model Context Protocol (MCP) Demo MCP Server, which means it retrieves data without modifying state.
Register the Solana Model Context Protocol (MCP) Demo MCP server in PolicyLayer and add a rule for getAccountInfo: 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 Model Context Protocol (MCP) Demo. Nothing to install.
getAccountInfo 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 getAccountInfo 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 getAccountInfo. 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.
getAccountInfo is provided by the Solana Model Context Protocol (MCP) Demo MCP server (solana-foundation/solana-dev-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
