It scans every MCP tool call in real time and blocks prompt injection, credential theft, and other threats. ## Preços e planos Free and open source (AGPL-3.0 licensed). No paid tier is listed; the project has been acquired by Docker Inc. ## Principais recursos e capacidades - **AI firewall:** Silently scans and protects all MCP tool calls flowing between your AI apps and their servers, without slowing your apps down. - **Layered threat detection:** Combines advanced LLM analysis with deterministic signatures to catch prompt injection, tool poisoning, credential theft, and command injection. - **Configurable scanning:** Bring your own LLM provider and API keys, and choose which signatures are used during scanning. - **Open source and free:** Free to download under the AGPL-3.0 license and now part of Docker Inc., with the source available on GitHub. ## Principais casos de uso - **Guard AI coding assistants (Developers):** Run MCP Defender as a background proxy while using Cursor or Claude, so any malicious tool call is flagged before it can cause harm. - **Protect credentials from agent misuse (Security engineers):** Rely on signature-based and LLM-based scanning to protect credentials and sensitive data that agents might otherwise expose. - **Monitor MCP communications (IT and platform teams):** Audit active MCP traffic and verification activity to understand which tools your AI apps are calling. - **Add a self-controlled defense layer (Privacy-conscious users):** Use an open-source, locally run proxy to add a security layer to agentic workflows without sending data to a third-party SaaS. ## Pontos fortes - Free and open source (AGPL-3.0) with source on GitHub - Real-time protection across multiple AI apps including Cursor, Claude, VS Code, and Windsurf - Layered detection combining LLM analysis and deterministic signatures - Bring your own LLM and API keys for full control ## Limitações - Requires you to supply your own LLM API keys for the LLM-based analysis layer - Runs as a local proxy, so it only protects AI apps on the machine where it is installed - As a young open-source project its signature and threat coverage continues to grow - Some threat data shown in the dashboard loads over the network rather than fully offline ## Perguntas frequentes ### What does MCP Defender do?
