# Story 1.10: `call-id` Tool Implementation (HTTP Operations)

Status: done

## Story

As an AI assistant,
I want to execute RabbitMQ Management API operations with validated parameters,
so that I can perform actual management tasks on RabbitMQ infrastructure.

## Acceptance Criteria

1. **Tool Registration and MCP Integration**
   - Tool `call-id` registered in MCP server tools list
   - Tool definition includes: name="call-id", description, input_schema (JSON Schema format)
   - Tool accessible via `tools/call` JSON-RPC method
   - Tool returns results via MCP content response format
   - Follows same registration pattern as `search-ids` and `get-id` tools

2. **Parameter Validation with Pydantic**
   - Accepts parameters: `operation_id` (string, required), `parameters` (object, optional)
   - Operation ID validated: non-empty string, exists in operations registry
   - Parameters validated against Pydantic schema for the specific operation (from Story 1.4)
   - Validation errors return specific messages: "Parameter 'vhost' is required" or "Parameter 'max_messages' must be integer ≥1"
   - JSON-RPC error code -32602 (invalid params) for validation failures
   - All validation errors include actionable remediation steps

3. **HTTP Request Construction and Execution**
   - Loads operation metadata from operations.json registry (loaded at startup)
   - Builds HTTP request from metadata:
     - URL path: Replace {vhost}, {name}, etc. placeholders with parameter values
     - HTTP method: GET, POST, PUT, PATCH, DELETE from operation metadata
     - Headers: Content-Type, Authorization (HTTP Basic Auth with configured credentials)
     - Request body: JSON serialized from parameters (for POST/PUT/PATCH)
   - URL encoding for path parameters (e.g., vhost "/" becomes "%2F")
   - Query parameters appended to URL for GET requests
   - Executes HTTP request via HTTPClient with connection pooling

4. **HTTP Client with Connection Pooling**
   - Uses httpx async client with connection pool (5 connections default, configurable)
   - TLS/SSL support with certificate verification (enabled by default)
   - Self-signed certificate support via `--insecure` flag (development only)
   - Connection timeout: 30 seconds (configurable via settings)
   - Request timeout: 30 seconds (fail-fast pattern, no automatic retries)
   - Connection pool timeout: 10 seconds when pool exhausted
   - HTTP Basic Auth with username/password from configuration

5. **Response Handling and Formatting**
   - Successful operations return: `{status: "success", result: {...}, correlation_id: "uuid"}`
   - Result contains actual RabbitMQ Management API response (parsed JSON)
   - Response validated against response_schema (if available in operations.json)
   - Response formatted for readability (pretty-printed JSON with 2-space indent)
   - Operations complete in <200ms at p95 latency for typical GET requests
   - Response includes metadata: operation_id, http_status_code, response_time_ms

6. **Error Handling and Resilience**
   - HTTP errors mapped to structured responses:
     - 404 Not Found → "Resource not found: {resource_type} '{resource_name}'"
     - 401 Unauthorized → "Authentication failed - check credentials"
     - 403 Forbidden → "Permission denied for operation on vhost '{vhost}'"
     - 500 Internal Server Error → "RabbitMQ server error: {error_details}"
     - Network errors → "Failed to connect to RabbitMQ at {host}:{port}"
   - Operations exceeding 30-second timeout aborted with: "Operation timed out after 30s"
   - Connection failures return immediately without retry (no blocking)
   - All errors include correlation_id for request tracing
   - Error responses use JSON-RPC error format with error codes
   - No sensitive data (passwords, tokens) logged in error messages

7. **Integration with Existing Components**
   - Reuses operations.json registry loaded by Story 1.7 server startup
   - Reuses Pydantic schemas generated by Story 1.4 for validation
   - Uses same operation_id format as search-ids and get-id tools (consistency)
   - Response format enables workflow chaining: search-ids → get-id → call-id
   - Logged with correlation_id for end-to-end request tracing
   - Follows async/await pattern consistent with other tools
   - Integrates with structlog for structured logging

## Dev Notes

### Architecture Patterns and Constraints

**HTTP Client Architecture (ADR-004, ADR-005):**
- Implements call-id tool from 3-tool semantic discovery pattern [Source: docs-bmad/sprint-artifacts/tech-spec-epic-1.md#System-Architecture-Alignment]
- Uses httpx async client with connection pooling (default 5 connections) [Source: docs-bmad/sprint-artifacts/tech-spec-epic-1.md#AC-10]
- Connection pooling reduces latency by reusing connections (avoid TCP handshake overhead) [Source: docs-bmad/sprint-artifacts/tech-spec-epic-1.md#Performance]
- TLS/SSL certificate verification enabled by default for security [Source: docs-bmad/sprint-artifacts/tech-spec-epic-1.md#Security]
- Fail-fast pattern: no automatic retries in Epic 1 (retry logic deferred to Epic 2) [Source: docs-bmad/sprint-artifacts/tech-spec-epic-1.md#Reliability]
- Stateless design: no shared state between tool calls [Source: docs-bmad/sprint-artifacts/tech-spec-epic-1.md#Non-Functional-Requirements]

**MCP Protocol Integration (ADR-001):**
- Tool registered with JSON-RPC 2.0 method: tools/call → call-id [Source: docs-bmad/sprint-artifacts/tech-spec-epic-1.md#AC-10]
- Input schema follows JSON Schema format with operation_id and parameters [Source: docs-bmad/sprint-artifacts/tech-spec-epic-1.md#APIs-and-Interfaces]
- Response format: MCP content with text/json containing execution result [Source: docs-bmad/sprint-artifacts/tech-spec-epic-1.md#MCP-Protocol-Interface]
- Error responses use JSON-RPC error code -32602 for invalid params [Source: docs-bmad/sprint-artifacts/tech-spec-epic-1.md#Non-Functional-Requirements]
- Response includes correlation_id for end-to-end request tracing [Source: docs-bmad/sprint-artifacts/tech-spec-epic-1.md#Observability]

**Parameter Validation and Type Safety:**
- All parameters validated with Pydantic schemas from Story 1.4 [Source: docs-bmad/sprint-artifacts/tech-spec-epic-1.md#AC-10]
- Validation errors list specific missing/invalid fields [Source: docs-bmad/sprint-artifacts/tech-spec-epic-1.md#AC-10]
- Type hints required for all function signatures (mypy --strict compliance) [Source: docs-bmad/architecture/implementation-patterns.md#Type-Safety]
- Use Pydantic BaseModel for ExecutionResult and ErrorResponse models [Source: docs-bmad/architecture/implementation-patterns.md#Data-Models]
- Constants: DEFAULT_TIMEOUT = 30, DEFAULT_POOL_SIZE = 5, MAX_RETRIES = 0 (no retry) [Source: docs-bmad/architecture/implementation-patterns.md#Constants]
- Async/await pattern for all tool handlers and HTTP operations [Source: docs-bmad/sprint-artifacts/tech-spec-epic-1.md#Architectural-Constraints-Followed]

**Error Handling and Resilience:**
- Error response schema: error_code, message, context, correlation_id, timestamp [Source: docs-bmad/architecture/implementation-patterns.md#Error-Handling]
- Error codes: CONNECTION_FAILED, VALIDATION_FAILED, OPERATION_TIMEOUT, RESOURCE_NOT_FOUND, AUTHENTICATION_FAILED, PERMISSION_DENIED [Source: docs-bmad/architecture/implementation-patterns.md#Error-Code-Categories]
- All error messages include actionable remediation steps [Source: docs-bmad/architecture/implementation-patterns.md#Error-Messages]
- Timeout handling: 30-second request timeout, 10-second pool timeout [Source: docs-bmad/sprint-artifacts/tech-spec-epic-1.md#Reliability]
- Connection failures return immediately (fail-fast, no retry) [Source: docs-bmad/sprint-artifacts/tech-spec-epic-1.md#AC-10]
- No sensitive data in error messages or logs (passwords, tokens sanitized) [Source: docs-bmad/sprint-artifacts/tech-spec-epic-1.md#Security]

**Code Quality Standards:**

[Note: Following project implementation patterns from docs-bmad/architecture/implementation-patterns.md]

- Follow PEP 8 style guide (enforced by black formatter)
- Maximum line length: 100 characters (configured in pyproject.toml)
- Docstrings required for all public classes and methods (Google style)
- Import order: stdlib → third-party → local modules [Source: docs-bmad/architecture/implementation-patterns.md#Import-Order]
- No unused imports (enforced by ruff linter)
- No bare except clauses (must catch specific exceptions)
- Use f-strings for string formatting (not % or .format())
- Avoid mutable default arguments (use None and initialize in function body)

### Learnings from Previous Story

**From Story 1-9-get-id-tool-implementation (Status: done)**

- **New Files Created**:
  - `src/rabbitmq_mcp_connection/tools/get_id.py` - get-id tool with LRU cached registry loading [Source: docs-bmad/sprint-artifacts/1-9-get-id-tool-implementation.md#File-List]
  - Tests: unit and integration tests for get-id tool (26 passing, 2 skipped legacy tests)

- **Modified Files**:
  - Registry loading pattern: LRU cached `_load_operations_registry()` loads data/operations.json once [Source: docs-bmad/sprint-artifacts/1-9-get-id-tool-implementation.md#Completion-Notes-List]
  - Response formatting: `_format_operation_cached()` with maxsize=256 for 132 operations

- **Performance Characteristics**:
  - Registry lookup: p50=0.02ms, p95=0.05ms, p99=1.03ms (well under <50ms target) ✅ [Source: docs-bmad/sprint-artifacts/1-9-get-id-tool-implementation.md#Completion-Notes-List]
  - LRU caching: maxsize=256 sufficient for all 132 operations in registry
  - File loading: data/operations.json (119KB, 132 operations) loads in <50ms

- **Tool Integration Patterns**:
  - Tool handlers are async functions: `async def handle_tool_name(arguments: Dict[str, Any])`
  - Parameter validation happens first: extract, validate, return error if invalid
  - Return format: `{"content": [{"type": "text", "text": json.dumps(result)}]}`
  - Error responses use MCP error format with JSON-RPC error code -32602
  - All tool calls logged with correlation_id for request tracing

- **Data Loading and Caching Patterns**:
  - Registry loaded at first use (lazy loading) and cached with LRU cache
  - Path calculation: use correct parent directory levels to find data/operations.json
  - Field name validation: operations.json uses "http_method" not "method"
  - Fuzzy matching: difflib.get_close_matches() for "did you mean" suggestions
  - Usage hints: authentication, modification (HTTP method), deprecation, rate limiting

- **Testing Patterns**:
  - Unit tests: 13 passing (includes fuzzy matching, usage hints, caching, correlation_id)
  - Integration tests: 13 passing (includes valid lookups, error cases, response format)
  - Performance validated: p95 < 50ms target exceeded by 1000x
  - Use actual operation IDs from registry in tests (not hardcoded)

- **Recommendations for This Story**:
  - **REUSE** operations.json registry loading from Story 1.9's get_id.py pattern
  - **FOLLOW** async tool handler pattern: `async def handle_call_id()`
  - **EXTEND** mcp_types.py with ExecutionResult and ErrorResponse models
  - **APPLY** same testing structure: unit (mocked), integration (real RabbitMQ), performance
  - **VALIDATE** parameters with Pydantic schemas from Story 1.4 before HTTP call
  - **LOG** all operation executions with correlation_id for request tracing
  - **SANITIZE** URLs, auth headers, and error messages (no passwords or tokens)
  - **USE** httpx async client for connection pooling (already installed)
  - **TEST** with testcontainers for real RabbitMQ instance in integration tests

2. O(1) lookup with <50ms p95 latency achieved (p95=0.05ms)
3. Complete operation details returned
4. Usage hints generated for auth, modification, deprecation, rate limiting
5. Error handling with fuzzy match suggestions
6. Response formatting with pretty-printed JSON and caching
7. Integration with operations.json registry

**Implementation highlights from Story 1-9:**
- Registry loading: LRU cached `_load_operations_registry()` loads data/operations.json once
- Performance: p50=0.02ms, p95=0.05ms, p99=1.03ms
- Caching: `_format_operation_cached()` with maxsize=256
- Structured logging: correlation_id tracking for all lookups

**Apply these patterns to Story 1.10:**
- Same registry loading approach for operation metadata
- Same correlation_id tracking for request tracing
- Same async/await pattern for tool handler
- Same MCP response format structure
- Same error handling with actionable messages

### Testing Strategy

[Source: Story 1.9 patterns for testing structure, docs-bmad/sprint-artifacts/tech-spec-epic-1.md#Test-Strategy-Summary]

**Unit Tests (tests/unit/rabbitmq_mcp_connection/test_executor.py, test_http_client.py):**
- Test HTTPClient initialization: connection pool configured with limits
- Test HTTPClient request method: HTTP method, URL, headers, body, timeout
- Test HTTPClient connection pooling: concurrent requests use pooled connections
- Test HTTPClient error handling: timeout, connection failure, SSL errors
- Test OperationExecutor initialization: HTTPClient and registry provided
- Test execute with valid operation: returns ExecutionResult with success status
- Test execute with invalid operation_id: raises error "Operation not found"
- Test execute with invalid parameters: raises ValidationError with specific field
- Test URL building: path parameters replaced, query params appended, URL encoded
- Test request body building: POST/PUT with body, GET/DELETE without body
- Test error mapping: 404→RESOURCE_NOT_FOUND, 401→AUTHENTICATION_FAILED, etc.
- Test timeout handling: httpx.TimeoutException → OPERATION_TIMEOUT
- Test connection failure: httpx.ConnectError → CONNECTION_FAILED
- Mock HTTPClient for controlled responses, mock operations.json for test data
- Achieve ≥90% code coverage for executor.py and http_client.py modules

**Integration Tests (tests/integration/rabbitmq_mcp_connection/test_call_id_tool.py):**
- Setup: Start RabbitMQ container with testcontainers (with Management Plugin enabled)
- Test tool registration: call-id in tools/list response from MCP server
- Test tool execution via MCP protocol: tools/call → call-id with real server
- Test successful operations: GET (queues.list), POST (queues.create), DELETE (queues.delete)
- Test parameter validation: missing required parameter, invalid parameter type
- Test HTTP errors: 404 (resource not found), 401 (auth failure), 403 (permission denied)
- Test connection pool: concurrent requests (10 simultaneous) with pool_size=5
- Test timeout: operation exceeding 30-second timeout (mock slow endpoint)
- Test correlation_id present in logs and response
- Verify MCP response format correctness (content type, structure, JSON-RPC compliance)
- Use real RabbitMQ container for comprehensive validation
- Teardown: Stop RabbitMQ container and clean up resources

**Performance Tests (tests/performance/test_call_id_performance.py):**
- Benchmark GET operation latency: p50, p95, p99 percentiles (<200ms p95 target from AC #5)
- Benchmark POST operation latency: queue creation operation
- Benchmark connection pool behavior: concurrent requests (10 simultaneous)
- Test connection pool exhaustion: 10 requests with pool_size=5, measure pool timeout
- Benchmark timeout handling: operation exceeding 30s (with mock)
- Statistical analysis with pytest-benchmark (n=100 runs for significance)
- Run on GitHub Actions runner (reference hardware for consistency)
- Mock RabbitMQ responses for consistent measurements (avoid network variability)

**Test Organization and Naming:**
- Follow pytest naming convention: test_*.py files, test_* functions
- Descriptive test names: test_execute_returns_success_for_valid_operation
- Group related tests in classes: TestHTTPClient, TestOperationExecutor, TestCallIdTool
- Use @pytest.mark.unit, @pytest.mark.integration, @pytest.mark.performance markers
- Parametrize tests for multiple scenarios: @pytest.mark.parametrize

**Mocking Strategy (Unit Tests):**
- Mock httpx.AsyncClient for controlled HTTP responses
- Mock operations.json loading for test data (5-10 sample operations)
- Mock Pydantic schema validation (test validation logic separately)
- Real implementations only in integration tests (real RabbitMQ container)
- Use unittest.mock.patch for external dependencies
- No mocking of core logic (URL building, request body building, error mapping)

**Coverage Requirements:**
- Overall test coverage: ≥80% (project standard)
- Critical paths: 100% coverage (execute, request, error mapping)
- Error handling: 100% coverage (all error types, timeout, connection failure)
- Use pytest-cov for coverage reporting: pytest --cov=src/rabbitmq_mcp_connection/executor --cov=src/rabbitmq_mcp_connection/http_client

**Request Tracing Validation:**
- Verify structured logging output format (JSON lines to stderr)
- Verify operation_id, parameters, status, duration_ms logged in each execution event
- Verify correlation_id present in logs (generated at start, propagated through call chain)
- Test log format consistency with search-ids and get-id tools (same structure)
