polish business entity lookup via krs api integration
Medium confidenceQueries the Polish National Court Register (KRS) API to retrieve authoritative business entity data including company names, registration numbers, legal status, and organizational details. The MCP server acts as a standardized interface layer that translates client requests into KRS API calls, handling authentication, rate limiting, and response parsing to expose entity information through a unified protocol.
Exposes the Polish KRS registry through the Model Context Protocol (MCP) standard, enabling LLM agents and AI tools to directly query authoritative government business data without custom API wrapper code. Uses MCP's tool-calling interface to abstract KRS API complexity.
Provides standardized MCP access to KRS data, eliminating the need for custom REST client implementations and enabling seamless integration with Claude and other MCP-compatible AI systems versus building direct KRS API clients.
mcp-based tool registration for krs queries
Medium confidenceImplements the Model Context Protocol (MCP) server specification to register KRS lookup as a callable tool that AI agents can discover and invoke. The server exposes tool schemas (name, description, input parameters) that conform to MCP's tool-calling standard, allowing compatible clients to understand available KRS operations and construct properly-formatted requests without hardcoding API details.
Implements MCP server specification to expose KRS as a first-class tool in the MCP ecosystem, using standardized tool schemas and discovery mechanisms rather than custom protocol wrappers. Enables direct integration with Claude's native tool-calling without adapter layers.
Leverages MCP's standardized tool interface for better AI agent compatibility and discoverability compared to custom REST wrappers or direct API clients, reducing integration friction for Claude and other MCP-aware systems.
entity data normalization and schema mapping
Medium confidenceTransforms raw KRS API responses into normalized, structured data formats suitable for downstream processing. The server parses KRS API JSON responses and maps fields to consistent schemas, handling variations in data representation, null values, and optional fields to ensure predictable output structure for client applications and AI agents consuming the data.
Provides transparent schema normalization at the MCP server layer, ensuring all clients receive consistently-formatted entity data regardless of KRS API response variations. Centralizes data transformation logic rather than pushing it to individual clients.
Normalizes KRS data at the server boundary, eliminating duplicate transformation logic across multiple clients and reducing data inconsistency issues compared to each client parsing raw KRS responses independently.
polish legal entity type classification and metadata extraction
Medium confidenceExtracts and classifies entity type information from KRS records (e.g., spółka z ograniczoną odpowiedzialnością, spółka akcyjna, fundacja, stowarzyszenie) and provides structured metadata about legal entity characteristics. The server parses KRS entity type codes or descriptions and maps them to standardized classifications, enabling downstream systems to understand entity legal structure without manual interpretation.
Provides domain-specific classification of Polish legal entity types with understanding of Polish business law structures (spółka z o.o., S.A., etc.), rather than generic entity type handling. Encodes Polish-specific business entity semantics in the MCP server.
Includes built-in Polish legal entity type classification and metadata extraction, eliminating the need for clients to maintain separate Polish business law reference data or implement custom type mapping logic.
krs search and filtering with query parameter handling
Medium confidenceAccepts structured search parameters (company name, registration number, location, entity type filters) and constructs appropriate KRS API queries with proper parameter encoding and validation. The server translates client-provided search criteria into KRS API-compatible query strings, handling special characters, Polish diacritics, and parameter combinations to enable flexible entity searches without exposing raw API complexity.
Handles Polish-specific search requirements including diacritics normalization and KRS API parameter encoding at the server layer, abstracting search complexity from clients. Provides unified search interface across multiple KRS query types.
Centralizes KRS search parameter handling and validation in the MCP server, reducing client-side search logic complexity and ensuring consistent query construction versus clients building raw KRS API queries independently.

Known Limitations
- ⚠Dependent on KRS API availability and uptime — no local caching mechanism documented
- ⚠Query latency varies with KRS API response times (typically 500ms-2s per request)
- ⚠Limited to Polish legal entities only — no cross-border entity lookup
- ⚠No bulk query optimization — each entity lookup requires a separate API call
- ⚠Requires MCP-compatible client — not usable with standard REST API clients or curl
- ⚠Tool schema complexity depends on KRS API parameter support — may require schema updates if KRS API changes
