Get information about a coin
AI agents call get_coin_info to retrieve information from Pump Fun Data 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 a coin from the Pump.fun platform. It performs no modifications, deletions, or external operations—purely a data read operation. Even if an AI agent misuses it by querying many coins, the blast radius is minimal (rate limiting or service degradation at worst). Severity is low because data retrieval alone poses minimal risk.
From the tool's definition Tool name 'get_coin_info' and description 'Get information about a coin' indicate a retrieval operation with no side effects.
Attacks that exploit this kind of access
Get information about a coin. It is categorised as a Read tool in the Pump Fun Data MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Pump Fun Data MCP Server MCP server in PolicyLayer and add a rule for get_coin_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 Pump Fun Data MCP Server. Nothing to install.
get_coin_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_coin_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_coin_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_coin_info is provided by the Pump Fun Data MCP Server MCP server (jun85664396/pump-fun-data-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
