Pump MCP Server

Security checks for vulnerabilities and agentic risk

Overview

This skill describes Solana wallet MCP operations with sensitive key handling, but the behavior is disclosed and aligned with its stated purpose.

Only use restore_keypair in a trusted local setup, and avoid pasting valuable private keys into agent transcripts or tool calls unless you understand how the MCP process, logs, and session state are handled. Generating a fresh keypair is safer for routine use.

A.I.G

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Finding

The skill exposes a restore_keypair capability but does not prominently warn that using it requires supplying highly sensitive secret key material to the MCP server process. In an AI-agent context, that omission is risky because users may paste private keys into a tool flow without understanding the exposure surface, including agent logs, prompts, transcripts, memory, or local process compromise.
