Solana Agent Audit MCP

An autonomous security audit MCP server and CLI utility designed for Solana programs, Anchor frameworks, and AI Agent Wallets.

Supports automated x402 payment headers and micropayments in USDC for pay-per-audit AI workflows.

Features

  • Program Vulnerability Scanner: Static analysis detecting missing Signer checks on authority accounts, unconstrained PDA derivations in invoke_signed, unverified external CPI program targets, and unsafe account closure resurrect vectors.

  • x402 Micropayment Protocol: Built-in paywall invoice generator that creates standardized x402 payment memos for automated agent-to-agent transactions.

  • Standard MCP Protocol: Implements Model Context Protocol tools (audit_solana_code and get_payment_invoice) compatible with Claude Code, Cursor, Codex, and OpenClaw.

Payout Recipient Configuration

All generated audit invoices route payments directly to the designated Solana recipient address:

Quickstart

1. Install & Build

npm install
npm run build
npm test

2. Configure with MCP Client (Claude Code / Cursor / Codex)

Add to your MCP configuration:

{
  "mcpServers": {
    "solana-auditor": {
      "command": "node",
      "args": ["dist/index.js"]
    }
  }
}

3. Available Tools

  • audit_solana_code({ sourceCode, programName }): Performs static security audit returning structured findings, severity, recommendations, and security score (0-100).

  • get_payment_invoice({ serviceName, amountUsdc }): Generates an x402 payment request invoice with recipient address and unique transaction memo.

    A3.7/5.0

    Scored across 2 tools

    Disambiguation5/5

    The two tools have completely distinct purposes: one audits Solana code, the other generates payment invoices. There is no overlap or ambiguity between them.

    Naming Consistency5/5

    Both tools follow a consistent verb_noun pattern (audit_solana_code, get_payment_invoice), making the naming predictable and clear.

    Tool Count3/5

    With only two tools, the server feels thin. The payment invoice tool is tangential to the core auditing purpose, making the tool count borderline for the stated domain.

    Completeness3/5

    The audit surface is minimal with only a single audit operation, lacking supporting features like audit history or status retrieval. The inclusion of payment invoicing is odd and doesn't fill functional gaps in the auditing workflow.

      Enables agents to run pre-signature security checks: identifying who can replace a Solana program's code or control an EVM contract's upgrades, surfacing dependency advisories for lockfiles, scanning public repos before release, and setting 30-day signed-webhook alerts on changes. Calls are paid per use in USDC over x402 from a wallet with per-call caps and a session budget.
