🪟 Windows Users: Additional MCP Server Configuration

If you're using Windows, you may need to configure MCP servers manually in mcp_agent.config.yaml:

# 1. Install MCP servers globally
npm i -g @modelcontextprotocol/server-brave-search
npm i -g @modelcontextprotocol/server-filesystem

# 2. Find your global node_modules path
npm -g root

Then update your mcp_agent.config.yaml to use absolute paths:

mcp:
  servers:
    brave:
      command: "node"
      args: ["C:/Program Files/nodejs/node_modules/@modelcontextprotocol/server-brave-search/dist/index.js"]
    filesystem:
      command: "node"
      args: ["C:/Program Files/nodejs/node_modules/@modelcontextprotocol/server-filesystem/dist/index.js", "."]

Note: Replace the path with your actual global node_modules path from step 2.

🔍 Search Server Configuration (Optional)

DeepCode supports multiple search servers for web search functionality. You can configure your preferred option in mcp_agent.config.yaml:

# Default search server configuration
# Options: "brave" or "bocha-mcp"
default_search_server: "brave"

Available Options:

• 🔍 Brave Search ("brave"):

  • Default option with high-quality search results
  • Requires BRAVE_API_KEY configuration
  • Recommended for most users

• 🌐 Bocha-MCP ("bocha-mcp"):

  • Alternative search server option
  • Requires BOCHA_API_KEY configuration
  • Uses local Python server implementation

API Key Configuration in mcp_agent.config.yaml:

# For Brave Search (default) - around line 28
brave:
  command: "npx"
  args: ["-y", "@modelcontextprotocol/server-brave-search"]
  env:
    BRAVE_API_KEY: "your_brave_api_key_here"

# For Bocha-MCP (alternative) - around line 74
bocha-mcp:
  command: "python"
  args: ["tools/bocha_search_server.py"]
  env:
    PYTHONPATH: "."
    BOCHA_API_KEY: "your_bocha_api_key_here"

💡 Tip: Both search servers require API key configuration. Choose the one that best fits your API access and requirements.
