11-11: LGTM!The import addition follows the established pattern and is correctly placed alphabetically within the imports.
38-38: LGTM!The command registration follows the established pattern and correctly adds the new MCP-related CLI functionality to the main CLI interface.
backend/aci/server/security_credentials_manager.py (1)
151-162: LGTM!The parameter reordering correctly aligns with the updated
OAuth2Managerconstructor signature whereclient_secretis now optional and positioned afterrefresh_token_url. The functionality remains unchanged.backend/aci/server/routes/linked_accounts.py (2)
354-363: LGTM!The parameter reordering in the
OAuth2Managerconstructor call correctly aligns with the updated signature whereclient_secretis positioned afterrefresh_token_url.
495-504: LGTM!The parameter reordering in the
OAuth2Managerconstructor call is consistent with the updated signature and maintains the OAuth2 callback flow functionality.backend/aci/common/schemas/security_scheme.py (3)
48-55: LGTM!The change to make
client_secretoptional is well-documented and appropriately supports MCP servers using dynamic client registration. The validation constraints are preserved for when the field is provided.
107-110: Good forward-thinking documentation.The TODO comment appropriately identifies that
OAuth2SchemeOverride.client_secretmay need similar treatment depending on the OAuth2Scheme configuration. This shows good architectural awareness.
187-187: LGTM!Making
client_secretoptional in the credentials model is consistent with the scheme definition and supports the MCP server dynamic registration pattern.backend/aci/server/oauth2_manager.py (3)
17-27: LGTM!The constructor signature change properly makes
client_secretoptional with appropriate typing (str | None) and default value (None). This supports MCP servers with dynamic client registration.
38-38: LGTM!The updated docstring clearly documents when
client_secretis optional, providing valuable context for MCP server-based applications using dynamic client registration.
101-101: Good forward-thinking comment.The TODO about potentially needing the "resource" parameter shows good awareness of MCP specification requirements and suggests this area may need future attention.
backend/aci/cli/commands/mcp.py (3)
1-15: LGTM!The imports are well-organized and appropriate for the CLI functionality. The MCP protocol version constant is clearly defined.
115-157: LGTM!The initialize function is well-implemented with proper JSON-RPC 2.0 structure, appropriate error handling, and clean session ID extraction from response headers.
161-200: LGTM!The tools listing function is well-implemented with proper JSON-RPC structure, comprehensive error handling, and appropriate type safety measures.

30-33: Incomplete implementation for declared security schemes.The help text declares support for "api-key" and "no-auth" security schemes, but only "oauth2" is implemented in the function body.
106-114: Broaden exception handling for initialization check.The function only catches
httpx.HTTPStatusErrorbut other exceptions like connection errors, timeouts, or JSON-RPC errors could occur during the tools listing attempt.
212-221: Intentional double underscore creation triggers unnecessary warning.The code intentionally creates function names with double underscores (
f"{app_name}__{tool['name']}") but then warns about consecutive underscores, creating noise in the output.
51-57: Good error handling but incomplete implementation.The use of
click.BadParameterfor CLI validation is appropriate. However, the function only implements OAuth2 authentication despite advertising "api-key" and "no-auth" in the CLI options.

1-15: LGTM! Clean imports and setup.The imports are well-organized and appropriate for the CLI functionality. The MCP protocol version constant is properly defined.
60-102: LGTM! Well-structured OAuth2 handler with good diagnostics.The function properly orchestrates the MCP workflow with performance timing, error handling, and comprehensive reporting. The fix for the tools[0] access issue is correctly implemented.
117-159: LGTM! Proper JSON-RPC 2.0 implementation.The function correctly implements the MCP initialize protocol with proper JSON-RPC formatting, error handling, and session management.
205-259: LGTM! Comprehensive function generation with good validation.The function creation logic is well-implemented with proper naming conventions, validation warnings, and file organization. The output directory structure and JSON formatting are appropriate.
261-282: LGTM! Proper event-stream handling with clear exception.The function now correctly raises a clear exception for unsupported event-stream responses instead of returning an empty dictionary, which addresses the previous concern about downstream processing issues.

1-15: LGTM!The imports are appropriate for the functionality and follow Python conventions. The MCP protocol version constant is well-defined.
17-40: LGTM!The app name validation is thorough and uses appropriate error handling with
click.BadParameter. The regex pattern and validation rules are clearly implemented.
86-124: LGTM!The OAuth2 handler function is well-structured with clear orchestration of the MCP interaction flow. The timing metrics and summary report provide good visibility into the process.
138-181: LGTM!The MCP initialization function properly implements JSON-RPC 2.0 protocol with appropriate error handling and session ID extraction. The implementation follows the specification correctly.
184-224: LGTM!The tools listing function properly implements JSON-RPC 2.0 protocol with appropriate error handling and response validation. The use of
castfor type safety is appropriate. The TODO for pagination handling is acceptable for initial implementation.
273-293: LGTM!The MCP response parsing function properly handles both JSON and event-stream formats. The event-stream parsing correctly extracts JSON data from SSE format and includes appropriate error handling.

232-232: Inconsistent underscore separator creates unnecessary warnings.The function intentionally uses double underscores (
__) as separator, but this creates consecutive underscores that will trigger warnings in the sanitization function, causing unnecessary noise in the output.Apply this diff to use single underscore:
- function_name = f"{app_name}__{_sanitize_orginal_tool_name(tool['name'])}" + function_name = f"{app_name}_{_sanitize_orginal_tool_name(tool['name'])}"
57-85: Remove unsupported security schemes from CLI choices.The CLI advertises "api-key" and "no-auth" security schemes but only implements "oauth2" authentication. This will cause runtime failures when users select the unsupported options.
Apply this diff to match implementation with advertised choices:

1-16: LGTM!The imports are appropriate for the CLI command functionality, and the MCP protocol version constant is properly defined.
18-41: LGTM!The app name validation is comprehensive, checking for valid characters, consecutive underscores, and leading/trailing underscores with clear error messages.
87-125: LGTM!The OAuth2 handler properly orchestrates the MCP server workflow with good timing metrics and status reporting.
139-182: LGTM!The initialize function properly implements JSON-RPC 2.0 initialize request with appropriate error handling and session ID extraction.

62-65: Fix advertised but unimplemented security schemesThe CLI advertises "api-key" and "no-auth" security schemes but only "oauth2" is implemented, causing runtime failures when users select other options.
Remove unsupported options from the choice list:
- type=click.Choice(["oauth2", "api-key", "no-auth"], case_sensitive=False), + type=click.Choice(["oauth2"], case_sensitive=False),
88-89: Use click.BadParameter for consistent CLI error handlingReplace ValueError with click.BadParameter for consistent CLI error patterns:
- raise click.BadParameter(f"Unsupported security scheme: {security_scheme}") + raise click.BadParameter(f"Unsupported security scheme: {security_scheme}")
139-141: Broaden exception handling for initialization checkThe function only catches
httpx.HTTPStatusErrorbut should handle other connection-related errors:- except httpx.HTTPStatusError: + except (httpx.HTTPStatusError, httpx.RequestError, click.ClickException):
237-237: Intentional double underscore creation triggers validation warningsThe function name construction uses double underscores (
f"{app_name}__{tool_name}") which intentionally creates consecutive underscores, but this conflicts with the app name validation that prohibits consecutive underscores.Use single underscore to avoid validation conflicts:
- function_name = f"{app_name}__{_sanitize_orginal_tool_name(tool['name'])}" + function_name = f"{app_name}_{_sanitize_orginal_tool_name(tool['name'])}"
300-315: Implement proper event-stream parsingThe function now properly parses event-stream responses instead of returning empty dict, which resolves the downstream processing issue.

1-21: LGTM - Clean imports and configuration setupThe imports are well-organized and the OpenAI client initialization follows the expected pattern for accessing configuration.
23-46: LGTM - Robust app name validationThe validation function properly handles all edge cases for app name formatting including character validation, consecutive underscores, and leading/trailing underscores. Error messages are clear and actionable.
371-371: Ignore the βgpt-4.1β model availability warning
The OpenAI API does support βgpt-4.1β as a valid model identifier, so no changes are needed here.Likely an incorrect or invalid review comment.
371-376: Ignore the suggested change:openai_client.responses.createis a valid OpenAI Python client methodThe OpenAI Python library ships a dedicated Responses API (
responses.create) that returns anoutput_textfield, distinct from thechat.completions.createendpoint. This method is officially documented and not deprecated, so no changes are needed here.Likely an incorrect or invalid review comment.

50-51: Correct union type extension for MCP protocol support.The protocol_data field has been properly extended to include MCPMetadata in the union type. The placement between RestMetadata and ConnectorMetadata is logical, maintaining the structured validation before the catch-all ConnectorMetadata.

19-54: Non-REST protocol validation is well-implemented.The validation logic appropriately handles CONNECTOR and MCP protocols with more flexible rules than REST. The recursive validation pattern and descriptive error messages are excellent.
Consider addressing the TODO comment about visible field validation (lines 34-38) in a future PR to fully enforce protocol-specific constraints for CONNECTOR/MCP protocols.

π Additional comments (14)
backend/aci/server/app_connectors/mock_app_connector.py (2)
41-41: LGTM! Parameter change is consistent.The parameter has been properly renamed and made optional with a sensible default value.
49-49: LGTM! Return value key updated consistently.The return dictionary key has been updated to match the renamed parameter.
backend/aci/common/tests/test_processor_filter_visible_properties.py (1)
34-34: LGTM! Test correctly reflects the new filtering behavior.The assertion properly verifies that when the "visible" field is absent, all properties remain visible, which aligns with the updated processor logic.
backend/aci/common/processor.py (1)
22-33: LGTM! Backward compatibility change for MCP protocol support.The logic correctly handles the case where "visible" field is missing by treating all properties as visible. The comprehensive comments and TODO note indicate this is a temporary solution for MCP protocol integration.
backend/aci/server/function_executors/base_executor.py (3)
8-8: LGTM! Import added for protocol-specific logic.The Protocol enum import is necessary for the conditional logic that follows.
55-56: LGTM! Clarifying comment added.The comment properly explains the current limitation and future intention for the filter_visible_properties function.
73-82: LGTM! Protocol-specific default injection.The conditional logic correctly restricts default value injection to REST protocol functions only, which is appropriate for MCP integration. The debug logging is properly moved inside the conditional block.
backend/aci/server/tests/routes/functions/test_functions_execute_mock_app_connector_with_no_auth_account.py (2)
26-30: LGTM! Test case updated to match parameter changes.The first test case properly reflects the parameter rename and includes appropriate security scheme metadata validation.
32-50: LGTM! Additional test case for custom optional parameter value.The second test case provides good coverage by testing custom values for the optional parameter while maintaining consistent security scheme metadata validation.
backend/aci/server/tests/dummy_apps/mock_app_connector/functions.json (1)
32-38: LGTM! Parameter schema correctly updated for optional handling.The parameter rename from "input_required_invisible_string" to "input_optional_string" and its removal from the required array accurately reflects the intended optional nature. The updated description and repositioned "additionalProperties" field maintain schema validity while supporting the new optional parameter pattern.
backend/aci/server/tests/routes/functions/test_functions_execute_mock_app_connector_with_oauth2_account.py (1)
11-51: Excellent test coverage for optional parameter scenarios.The expanded parameterization effectively tests both default value injection (when the optional parameter is omitted) and custom value handling (when explicitly provided). The consistent parameter naming and proper inclusion of OAuth2 security scheme metadata in expected responses ensure thorough validation of the updated mock connector behavior.
backend/aci/common/validator.py (3)
4-16: Well-designed protocol-specific validation entry point.The new
validate_function_parameters_schemafunction provides clean protocol-based dispatch using a match statement, properly handling REST, CONNECTOR, and MCP protocols with appropriate error handling for invalid protocols.
57-127: REST protocol validation maintains backward compatibility.The REST-specific validation function correctly preserves all existing strict validation rules while properly calling the root-level validator and maintaining recursive validation with the REST-specific function. This ensures backward compatibility for existing REST protocol functions.
130-167: Root-level REST validation is properly separated and implemented.The root-level validation function cleanly handles top-level schema constraints, properly using the HttpLocation enum for allowed keys and providing specific error messages for various validation failures.
