THE RISK

Low Risk

Why searchTokens needs a policy

searchTokens is a pure information retrieval tool. It searches for tokens and returns data about them (market data, bonding curve status, social links). This is a read-only query operation with no side effects, matching the 'Read' category definition. The severity is low because misuse would only expose publicly available token information, with no blast radius for destructive or financial harm.

From the tool's definition Tool performs a search query that 'returns matching tokens with market data, bonding curve status, and social links'—it retrieves and queries data without modifying any state.

POLICY

How to control searchTokens

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 searchTokens:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "searchTokens": {}
  }
}

searchTokens is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Pump Fun MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

How do I block searchTokens completely? +

Set action: deny in the PolicyLayer policy for searchTokens. 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.

What MCP server provides searchTokens? +
