Stack Overflow Model Context Protocol (MCP)

The Stack Overflow Model Context Protocol (MCP) enables AI tools and agents to access trusted developer knowledge from Stack Overflow. It standardizes how knowledge is exposed, discovered, and retrieved for use in agent workflows and developer environments.

Access

Access to the Stack Overflow MCP server is limited to 100 calls per day per Stack Exchange user. If you have use cases that exceed this amount, please contact our sales department.

Setup an MCP Client

To connect to the Stack Overflow MCP Server, you will configure your client to use the remote server. This allows you to continue your tasks across devices with a single login after authentication, without needing to install and run the server locally. Use your preferred MCP client for this procedure.

Prerequisites

  • An MCP-compatible client or agent runtime.
  • A Stack Overflow account for authentication.

Setup

  1. Open the configuration file for your MCP client in a text editor, and replace the configuration with the following configuration.
{  
    "mcpServers": {  
        "stack-mcp-server": {  
            "command": "npx",  
            "args": [  
                "mcp-remote",  
                "mcp.stackoverflow.com"  
            ]  
        }  
    }  
}
  1. Save the file, and restart your MCP client. The MCP client will send you to the Stack Exchange login page.
  2. Provide your consent for the client to work with the MCP server:
    1. Log into Stack Exchange when the login page appears.
    2. Authorize the client to work with the MCP server.
      1. Read and accept the terms and conditions
  3. Quit and reopen your MCP client.
  4. To test your integration, ask the MCP client to perform one of the supported tasks.

Available tools

The following tools are supported for integration with Stack Overflow knowledge resources:

  • so_search: Performs lexical search over questions
  • get_content: Allows content including questions, answers, comments to be retrieved by ID

Additional tools may be added in future phases.

Use Case: Powering community and AI projects

For individual developers, small teams, or startups looking to prototype new ideas, Stack Overflow’s vast knowledge base is now easier to integrate than ever. If you are creating specialized, open-source, or other community-focused AI tools, you can leverage Stack Overflow's trusted data without the need for complex, custom integrations.

How it works:

  • Effortless connection: With minimal setup, you can connect your AI agent or application directly to Stack Overflow's MCP.
  • Access rich knowledge: Your tool can retrieve relevant questions and answers, delivering trusted Stack Overflow content directly to your end-users.
  • Simple authentication: Users simply authenticate with their existing Stack Overflow account to get started.
  • Built-in attribution: Attribution to Stack Overflow is consistently included with the retrieved content, ensuring the source is always clear.

To support prototyping and community projects, authenticated users can make up to 100 API calls per day.

What you can build

Stack Overflow’s data can support a wide range of lightweight, exploratory tools — especially those that enhance developer workflows through real-time context. Here are some examples of what you might build:

  • AI assistants that surface relevant Stack Overflow answers at runtime
  • RAG-powered tools that ground LLM outputs in trusted community content
  • Developer extensions that offer contextual help while coding or debugging
  • Chatbots that fetch solutions from Stack Overflow when users get stuck
  • Learning tools that supplement tutorials with real-world examples
  • Dashboards or research tools that explore developer trends over time
  • Experimental interfaces that reimagine how developers engage with technical knowledge
