AI agents call list-accounts to retrieve information from Pump Fun 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 accounts stored locally without altering, creating, or deleting any data. It performs a simple directory listing operation, which is a read-only action. Given the context of a trading platform, exposure of account information could be sensitive, but the tool itself performs no destructive, executable, or financial operations.
From the tool's definition Tool name 'list-accounts' and description 'List all accounts in the keys folder' indicates a query/enumeration operation with no modifications or side effects.
Documented attack patterns abuse exactly the kind of access list-accounts gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Pump Fun MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list-accounts:
{
"version": "1",
"default": "deny",
"tools": {
"list-accounts": {}
}
}list-accounts is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all accounts in the keys folder. It is categorised as a Read tool in the Pump Fun MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Pump Fun MCP Server MCP server in PolicyLayer and add a rule for list-accounts: 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 Pump Fun MCP Server. Nothing to install.
list-accounts 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-accounts 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-accounts. 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-accounts is provided by the Pump Fun MCP Server MCP server (noahgsolomon/pumpfun-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Pump Fun MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
