Get the SOL and token balances for an account
AI agents call get-account-balance 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 queries and retrieves balance information without side effects. It is a straightforward read operation that poses minimal risk—the account holder's balance data is already public on the blockchain. An AI agent misusing this would at worst retrieve balances it shouldn't see, but cannot move funds or execute irreversible actions.
From the tool's definition Tool name is 'get-account-balance' and description states it retrieves ('Get') account balances. No creation, modification, deletion, or execution of transactions occurs.

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 get-account-balance:
{
"version": "1",
"default": "deny",
"tools": {
"get-account-balance": {}
}
}get-account-balance is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the Pump Fun MCP Server MCP server in PolicyLayer and add a rule for get-account-balance: 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.
get-account-balance 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-account-balance 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-account-balance. 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-account-balance 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.
