重要提示： 服务器发送事件（SSE）传输被弃用，并由新的HTTP Streamable传输取代。SSE仍可兼容遗留，但HTTP Streamable现为所有新实现的推荐方法。

这是一个n8n社区节点，允许你在n8n工作流中与模型上下文协议（MCP）服务器交互。

MCP 是一种协议，使 AI 模型能够以标准化方式与外部工具和数据源交互。该节点允许您连接到 MCP 服务器、访问资源、执行工具并使用提示。

N8N 是一个公平代码许可的工作流程自动化平台。

Important Note: The Server-Sent Events (SSE) transport is deprecated and replaced by the new HTTP Streamable transport. SSE remains available for legacy compatibility, but HTTP Streamable is now the recommended method for all new implementations.

This is an n8n community node that lets you interact with Model Context Protocol (MCP) servers in your n8n workflows.

MCP is a protocol that enables AI models to interact with external tools and data sources in a standardized way. This node allows you to connect to MCP servers, access resources, execute tools, and use prompts.

n8n is a fair-code licensed workflow automation platform.

Installation

Follow the installation guide in the n8n community nodes documentation.

Also pay attention to Environment Variables for using tools in AI Agents. It’s mandatory to set the N8N_COMMUNITY_PACKAGES_ALLOW_TOOL_USAGE environment variable to true if you want to use the MCP Client node as a tool in AI Agents.

Credentials

The MCP Client node supports three types of credentials to connect to an MCP server:
