❗Breaking Changes

  1. API JSON Response Format: Standardized JSON property names to camelCase (#114)

    • Health API:
      • last_checked → lastChecked
      • last_successful → lastSuccessful
    • Configuration Fields:
      • required_env → requiredEnv
      • required_args → requiredArgs
      • required_args_bool → requiredArgsBool
      • display_name → displayName
      • is_official → isOfficial
    • Tool Schema Fields:
      • input_schema → inputSchema
      • output_schema → outputSchema
      • read_only_hint → readOnlyHint
      • destructive_hint → destructiveHint
      • idempotent_hint → idempotentHint
      • open_world_hint → openWorldHint
    • Runtime Usage Fields:
      • actual_name → actualName
    • HTTP API clients will need to update field mappings

  2. Configuration Structure: Split required_args into required_args (value arguments) and required_args_bool (boolean flags) for more granular argument validation (#105)

    • Existing .mcpd.toml files using required_args may need to be updated if they contained boolean required arguments
    • Boolean flags (like --verbose) should now be specified under required_args_bool
    • Value arguments (like --config=value) remain under required_args

  3. Export Template Variables: Simplified template variable naming by removing ARG suffix from command-line arguments.

    • Both environment variables and arguments now use the unified format MCPD__{SERVER_NAME}__{VARIABLE_NAME}.
    • Users with existing CI/CD pipelines may need to rename their environment variables (e.g., MCPD__SERVER__ARG__TOKEN → MCPD__SERVER__TOKEN) if they recreate files from export

New Features

  • Complete Config Export: Fully implemented mcpd config export command (#106)

    • Now processes both config and runtime files (was runtime-only before)
    • Generates portable execution context (e.g. secrets.prod.toml) with templated variables
    • Creates environment contract (e.g. .env) with placeholder mappings for CI/CD systems
    • Supports consistent placeholder naming: MCPD__{SERVER_NAME}__{VAR_NAME}
    • Handles server names with hyphens (converts to underscores in placeholders)

  • Format Support for Add Command: Added --format flag support to mcpd add (#102)

    • Consistent output formatting across commands (text, JSON, YAML)
    • Improved package addition workflow with structured output options

  • Enhanced Runtime Support: Refactored runtime specifications with security fixes for NPX(#104)

  • Homebrew Distribution: Added Homebrew tap support for easy installation (#115)

    • Users can now install via: brew tap mozilla-ai/mcpd && brew install mcpd
    • Includes automatic shell completion installation (bash, zsh)

Improvements

  • Development Experience: Include log file path in development banner when configured (#109)
  • Code Quality: Added comprehensive golangci-lint configuration with automated formatting (#114)
  • Documentation: Updated README and contributing guidelines (#99)
  • License: Fixed copyright attribution (#100)
  • CI/CD: Improved documentation deployment process (#95)

Technical Details

  • Enhanced argument validation with separate handling for value and boolean arguments
  • Comprehensive test coverage for export functionality
  • Improved error handling and validation across commands
  • Better placeholder name consistency in configuration exports
