@Smithery

MCP server for USDC micropayments on Base. Pay for x402-gated content, APIs, or services — when a URL returns HTTP 402, check the payment gate, execute an on-chain USDC payment through a verified splitter contract, and receive a time-limited Bearer access token to unlock the resource. No API keys, no signup, fully non-custodial. Auto-generates a wallet on first run — zero config to start. Works with Claude Desktop, Cursor, Windsurf, and any Model Context Protocol client.

Risk Summary

Needs Approval

Excessive Permissions plus Missing Rate Limits raises enough risk that this tool should not be auto-trusted.

Potential impact: The agent may gain overly broad access to files, network, databases, or execution capabilities.

Recommended action: Keep this tool behind manual approval and avoid unattended runs until the risky capabilities are narrowed or removed.

Suggested policy: keep this tool behind manual approval, do not allow unattended runs, and re-scan after narrowing risky permissions.

Security Findings (10)

  • HighAS-002

    ⚠️Excessive Permissions ×4

    tool declares network permission

    xenarch_check_gatexenarch_payxenarch_get_history

    tool declares exec permission

    xenarch_pay

    Fix: Tool requests broad permissions (exec/fs/network). Validate input parameters using Enums where possible, and restrict file system operations to explicit allowed directories.

  • LowAS-011

    ℹ️Missing Rate-Limit / Timeout ×3

    tool performs network or execution operations but declares no rate-limit, timeout, or retry configuration

    xenarch_check_gatexenarch_payxenarch_get_history

    Fix: Declare explicit rate-limit, timeout, and retry configuration for all network and execution tools. Implement exponential back-off and surface resource state to the calling agent.

  • InfoAS-014

    ℹ️Dependency Inventory Unavailable ×3

    Tool did not expose metadata.dependencies or repo_url, so supply-chain coverage is limited.

    xenarch_check_gatexenarch_payxenarch_get_history

    Fix: Review and remediate the identified issue.

Scan this tool yourself

Reproduce this audit locally, integrate into CI, or let your agent audit its own tools.

Install once, then scan any MCP server:

$ curl -sfL https://raw.githubusercontent.com/AgentSafe-AI/tooltrust-scanner/main/install.sh | bash
$ tooltrust-scanner scan --server "npx -y xenarch-xenarch-mcp"

Adjust the package name if your npm registry name differs from the tool ID. View source
