+# Using the Model Context Protocol (MCP) in Jan
+
+Jan now supports the **Model Context Protocol (MCP)**, an open standard designed to allow language models to
+interact with external tools and data sources.
+
+MCP acts as a common interface, standardizing the way an AI model requests to perform an action and how it
+receives data from a tool. This enables a model to connect to any MCP-compliant tool without requiring custom integration work.
+
+This document outlines the benefits, risks, and implementation of MCP within Jan.
+
+## Core Benefits of MCP
+
+Integrating MCP provides a structured way to extend the capabilities of the models you use in Jan. Here are the three
+
+
+* **Standardization:** MCP aims to solve the "M x N" integration problem, where every model (M) needs a
+unique connector for every tool (N). By adapting to a single standard, any compliant model can interface with any compliant tool.
+* **Extensibility:** This allows you to augment your models with new abilities. For instance, an AI can be granted
+access to search your local codebase, query a database, or interact with web APIs, all through the same protocol.
+* **Flexibility:** Because the interface is standardized, you can swap out models or tools with minimal friction,
+making your workflows more modular and adaptable over time.
+
+<Callout type="warning">
+    Please note that not all models that you can download and use, whether in Jan or other tools, may be good at
+    tool calling or compatible with MCP. Make sure that the model you choose is MCP-compliant before integrating
+    it into your workflows. This might be available in the model card or you may need to implement it yourself to
+    test the capabilities of the model.
+</Callout>
+
+## Considerations and Risks
+
+While powerful, MCP is an evolving standard, and its use requires careful consideration of the following points:
+
+* **Security:** Granting a model access to external tools is a significant security consideration. A compromised
+tool or a malicious prompt could potentially lead to unintended actions or data exposure. Jan's implementation
+focuses on user-managed permissions to mitigate this risk, meaning, you have to turn on the permission for each
+tool individually.
+* **Standard Maturity:** As a relatively new protocol, best practices or sensible defaults are still being
+established. Users should be aware of potential issues like prompt injection, where an input could be crafted to
+misuse a tool's capabilities.
+* **Resource Management:** Active MCP connections may consume a portion of a model's context window, which could
+affect performance (i.e., the more tools the model and the larger the context of the conversationhas the longer
+you will need to wait for a response). Efficient management of tools and their outputs is important.
+
+
+## Configure and Use MCPs in Jan
+
+We have integrated an MCP client into Jan to help users in connecting tools to their workflows.
+
+### 0. Pre Setup
+
+You will need to have `node` and/or `python` installed on your machine. If you don't have them installed, you can
+download them from the official websites:
+- [Node.js](https://nodejs.org/)
+- [Python](https://www.python.org/)
+
+### 1. Initial Setup
+
+Before connecting to a tool, you must first enable Jan's MCP host. Navigate to `Settings` > `MCP Servers` and toggle
+the `Enable MCP Host` switch.
+
+![Turn on the MCP Host](./_assets/mcp-on.png)
+
+### 2. Adding an MCP Server
+
+Once the host is enabled, you can connect Jan to one or more MCP tool servers.
+
+- Click on the `+` sign on the upper right-hand corner of the MCP box.
+
+![Add New Server](./_assets/mcp-setup-1.png)
+
+- Enter the following details to configure the BrowserMCP:
+  - **Server Name**: `browsermcp`
+  - **Command**: `npx`
+  - **Arguments**: `@browsermcp/mcp`
+  - **Environment Variables**: You can leave this field empty.
+
+![Configure BrowserMCP](./_assets/mcp-setup-2.png)
+
+- Check that the server has been activated successfully.
+
+![Server Confirmation](./_assets/mcp-setup-3.png)
+
+
+### 3. Using an MCP Tool in a Chat
+
+With a server connected, models that support tool use can now request access to your configured MCP. As of now,
+the best models to use MCP are Claude 4 Sonnet, 4 Opus
+
+#### 3.1 Local Models
+
+- Start a chat with a model capable of tool use and enable tool calling via the UI.
+
+
+#### 3.2 Cloud-based Models
+
+- Go to **Model Providers > Anthropic** and, after you have entered your API key, enable tool
+calling via the UI.
+
+![Enable Tool Calling](./_assets/mcp-setup-4.png)
+
+- Open up a new chat with, say, Claude 4 Sonnet, and send a request that requires the model to use the browser.
+
+![Start Chatting](./_assets/mcp-setup-5.png)
+
+
+## Troubleshooting
+
+[This is a place for you to add solutions to common problems. For example:]
+
+* **Problem:** The MCP server appears as "Disconnected."
+    * **Solution:** [Your troubleshooting steps here. e.g., "Verify the server address is correct and that the server is running on your machine. Check for firewall rules that may be blocking the connection..."]
+* **Problem:** A model is not attempting to use any tools.
+    * **Solution:** [Your troubleshooting steps here. e.g., "Ensure the model you are using supports tool-use. Not all models have this capability..."]
+
+
+## Future Potential
+
+This integration is the foundation for creating more capable and context-aware AI assistants within Jan. The long-term
+goal is to enable complex workflows that leverage your local environment securely.
+
+For example, an AI could cross-reference information between a local document and a remote API, or use a local script to
+analyze data and then summarize the findings, all orchestrated through Jan's interface. As the MCP ecosystem grows, so
+will the potential applications within Jan.
