MCP security checks — WARDEN and HISTOR
Scan MCP tool definitions for poisoning, look up server history, count tool-list tokens. Free.
我該用這個嗎
品質與安全性
根據工具定義與協定合規性的自動化分析。
上下文成本
這是每次將伺服器的工具載入模型上下文時所消耗的約略 token 數量。數量越高，可用於其他工作的注意力就越少。

工具（4）
🟢warden_scan(tools, server)
Scan an MCP server's tools/list with WARDEN, the open-source MCP firewall: static rules and a threat list over every name, description, schema and annotation. Returns allow or block and each finding with its rule and severity. Quoted fragments of the scanned text are left out of the answer.

"server": {

}
},

"tools"
]
}🟢histor_check(endpoint, name)
Look up an MCP server in HISTOR, a public append-only log of MCP tool sets: when its tool set was first pinned, how often it changed, and what the pattern scan found. HISTOR answers from its own observations and never contacts the server.

"description": "https URL of the MCP server"
},
"name": {
"type": "string",
"description": "Or its registry name, e.g. io.github.owner/server"
}
}
}🟢tool_list_cost(tools, server)
How many tokens an MCP server's tool list adds to every model request, what that costs per 1,000 requests, the heaviest tools, and where it sits among 18,204 packages and 16,170 remote servers. Send a tools/list or name a server HISTOR observes.

}🟢x402_check(x_payment, requirements, authorization, signature, network)
Check a signed x402 USDC payment before submitting it: recovers the EIP-712 signer, runs USDC's own checks and the seller's terms, and when the signature fails names the domain it was really made for (e.g. Base Sepolia's 'USDC' used on Base, where USDC is 'USD Coin').
