根据 OpenAITools.app 于 2026-11-11 核对的流量数据，MCP Defender（mcpdefender.com）是一个收录在 Large Language Models (LLMs) 下的 AI 平台，月访问量为 0，月度环比流量变化为 +0（0%）。其主要地理市场为全球（— 流量份额），采用免费定价模式。按月流量计算的主要竞争替代方案包括 Ollama（942.2万次访问/月），Mindgard（15.35万次访问/月），ModelScope（308.54万次访问/月）。
用 Cursor 和 Claude 连 MCP 的必备安全护盾，防住了一次恶意的 prompt injection。
开源的 MCP 代理，总算能放心调各种第三方工具了。
Docker 背书就是稳，拦截很及时。
配置起来比想象中简单，对开发者太友好了。
以下短评基于实时网页探查、定价机制与同类产品基准由 AI 综合模拟生成，旨在呈现不同使用场景下的常见槽点与亮点，非实名真实用户评价。
Silently scans and protects all MCP tool calls flowing between your AI apps and their servers, without slowing your apps down.
Combines advanced LLM analysis with deterministic signatures to catch prompt injection, tool poisoning, credential theft, and command injection.
Bring your own LLM provider and API keys, and choose which signatures are used during scanning.
Free to download under the AGPL-3.0 license and now part of Docker Inc., with the source available on GitHub.
MCP Defender is a free, open-source desktop app that acts as a security proxy between AI apps like Cursor and Claude and their MCP servers. It scans every MCP tool call in real time and blocks prompt injection, credential theft, and other threats.
Run MCP Defender as a background proxy while using Cursor or Claude, so any malicious tool call is flagged before it can cause harm.
Rely on signature-based and LLM-based scanning to protect credentials and sensitive data that agents might otherwise expose.
Audit active MCP traffic and verification activity to understand which tools your AI apps are calling.
Use an open-source, locally run proxy to add a security layer to agentic workflows without sending data to a third-party SaaS.
