* **Business Perspective:** Declaration data supports compliance monitoring products

/**
* Handles the get_mep_declarations MCP tool request.
*
* Retrieves MEP declarations of financial interests filed under the Rules of Procedure.
* Supports both single-declaration lookup by document ID and list retrieval with optional
* year filtering. Financial declaration data enables conflict-of-interest detection,
* lobbying pattern analysis, and transparency assessments.
*
* @param args - Raw tool arguments, validated against {@link GetMEPDeclarationsSchema}
* @returns MCP tool result containing either a single MEP financial declaration document
* or a paginated list of declarations, optionally filtered by filing year
* @throws - If `args` fails schema validation (e.g., invalid year or limit
* out of range 1–100)
* - If the European Parliament API is unreachable or returns an error response
*
* @example
* ```typescript
* // List declarations for a specific year
* const result = await handleGetMEPDeclarations({ year: 2024, limit: 20 });
* // Returns up to 20 financial declarations filed in 2024
*
* // Fetch a single declaration by document ID
* const single = await handleGetMEPDeclarations({ docId: 'DECL-2024-001' });
* // Returns the full declaration document
* ```
*
* @security - Input is validated with Zod before any API call.
* - Access to financial declarations (personal data) is audit-logged per GDPR Art. 6(1)(e)
* and ISMS Policy AU-002. Data minimisation applied per GDPR Article 5(1)(c).
* @since 0.8.0
* @see {@link getMEPDeclarationsToolMetadata} for MCP schema registration
* @see {@link handleGetMEPDetails} for retrieving broader MEP profile information
