Enabling or Disabling Built-in Features

You can selectively enable or disable built-in tools, resources, and prompts; all features are enabled by default. When a feature is disabled:

- It is not advertised to the LLM in list operations
- Attempts to use it return an error message

Within the builtins section of the configuration file, you can indicate if you would like the feature to be enabled (true) or disabled (false):

builtins:
  tools:
    query_database: true        # Execute SQL queries
    get_schema_info: true       # Get schema information
    similarity_search: false    # Disable vector similarity search
    execute_explain: true       # Execute EXPLAIN queries
    generate_embedding: false   # Disable embedding generation
    search_knowledgebase: true  # Search documentation knowledgebase
  resources:
    system_info: true           # pg://system_info
  prompts:
    explore_database: true      # explore-database prompt
    setup_semantic_search: true # setup-semantic-search prompt
    diagnose_query_issue: true  # diagnose-query-issue prompt
    design_schema: true         # design-schema prompt

Notes

The read_resource tool is always enabled as it is required for listing resources.
Features can also be disabled by other configuration settings (e.g., search_knowledgebase requires knowledgebase.enabled: true).
