Default value for `limit` changed from 5 to 4 in description

The description of the limit field was updated to reflect a new default value of 4 (previously documented as 5). This is a documentation change, but if clients rely on the stated default to predict result counts without explicitly setting limit, they may see one fewer result than expected.

    aws___list_regions description added

    The aws___list_regions tool description was updated from an empty string to "Retrieve a list of all AWS regions." This is a documentation improvement that clarifies the tool's purpose without changing any functional behavior.

  • Informational

    Simplify tool descriptions and parameter docs

    Tool descriptions and parameter documentation for aws___get_regional_availability and search_documentation were significantly condensed and refactored to be more concise. The changes clarify usage guidance and parameter behavior but do not alter the underlying API contract, request/response structure, or functional behavior. Parameter resource_type is now explicitly documented as required for aws___get_regional_availability.

  • Breaking

    Remove aws___recommend tool from AWS Knowledge MCP

    The aws___recommend tool has been entirely removed from the AWS Knowledge MCP API. Any integration or agent workflow that calls aws___recommend to fetch related documentation page recommendations (Highly Rated, New, Similar, Journey categories) will now fail — the tool no longer exists in the spec.

  • Additive

    Add openWorldHint and destructiveHint annotations to tools

    Three MCP tools (aws___get_regional_availability, aws___list_regions, aws___read_documentation) now include two new annotation fields: openWorldHint: false and destructiveHint: false. These additions clarify tool behavior characteristics and are backward-compatible.

  • Informational

    Documentation updates to tool descriptions

    Updated descriptions for aws___get_regional_availability and aws___list_regions tools with expanded guidance on when NOT to use each tool and clarified best practices. These are documentation-only changes that improve tool discoverability and reduce misuse, but do not alter API behavior or parameters.
