--- title: MCP Client Tool node documentation description: Learn how to use the MCP Client Tool node in n8n. Follow technical documentation to integrate MCP Client Tool node into your workflows. contentType: [integration, reference] --- # MCP Client Tool node The MCP Client Tool node is a [Model Context Protocol (MCP)](https://modelcontextprotocol.io/introduction) client, allowing you to use the tools exposed by an external MCP server. You can connect the MCP Client Tool node to your models to call external tools with n8n agents. ```{note} Credentials The MCP Client Tool node supports [Bearer](/08-0-0-Workflow/integrations/builtin/credentials/httprequest.md#using-bearer-auth), generic [header](/08-0-0-Workflow/integrations/builtin/credentials/httprequest.md#using-header-auth), and [OAuth2](/08-0-0-Workflow/integrations/builtin/credentials/httprequest.md#using-oauth2) authentication methods. ``` ## Node parameters Configure the node with the following parameters. * **SSE Endpoint**: The SSE endpoint for the MCP server you want to connect to. * **Authentication**: The authentication method for authentication to your MCP server. The MCP tool supports [bearer](/08-0-0-Workflow/integrations/builtin/credentials/httprequest.md#using-bearer-auth), generic [header](/08-0-0-Workflow/integrations/builtin/credentials/httprequest.md#using-header-auth), and [OAuth2](/08-0-0-Workflow/integrations/builtin/credentials/httprequest.md#using-oauth2) authentication. Select **None** to attempt to connect without authentication. * **Tools to Include**: Choose which tools you want to expose to the AI Agent: * **All**: Expose all the tools given by the MCP server. * **Selected**: Activates a **Tools to Include** parameter where you can select the tools you want to expose to the AI Agent. * **All Except**: Activates a **Tools to Exclude** parameter where you can select the tools you want to avoid sharing with the AI Agent. The AI Agent will have access to all MCP server's tools that aren't selected. ## Templates and examples ## Related resources n8n also has an [MCP Server Trigger](/08-0-0-Workflow/integrations/builtin/core-nodes/n8n-nodes-langchain.mcptrigger.md) node that allows you to expose n8n tools to external AI Agents. Refer to the [MCP documentation](https://modelcontextprotocol.io/introduction) and [MCP specification](https://modelcontextprotocol.io/specification/) for more details about the protocol, servers, and clients. ```{include} ../../../../../_snippets/integrations/builtin/cluster-nodes/tools-link.md ``` ```{include} ../../../../../_snippets/integrations/builtin/cluster-nodes/langchain-overview-link.md ```
