Migration Guide

Upgrading to 0.2.0

The main change in 0.2.0 is that you no longer need to add hexdocs_mcp as a dependency in your project's mix.exs. Instead, the functionality is now provided through pre-built binaries that are automatically downloaded when using the MCP server.

1. Remove the following from your mix.exs:

{:hexdocs_mcp, "~> 0.1", only: :dev, runtime: false}

2. If you've updated any dependencies to be available in :dev (like :floki), you can revert those changes if they're no longer needed for other purposes.

3. Ensure your MCP client configuration is set up correctly (this should already be the case if you were using version 0.1.x):

{
  "mcpServers": {
    "hexdocs-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "hexdocs-mcp"
      ]
    }
  }
}

That's it! The MCP server will now automatically handle downloading and using the appropriate binary for your platform.
