entyrix-mcp

Model Context Protocol (MCP) server for the Entyrix European business-registry (KYB) API. Exposes 10 stdio tools so LLM clients (Claude Desktop, Claude Code, Cursor, ChatGPT) can search, look up, and analyze companies across SK, CZ, AT, EE, SI, LV, UK and more (16+ jurisdictions, growing).

30-second quickstart

npm install -g entyrix-mcp
export ENTYRIX_API_KEY=your-api-key-here
entyrix-mcp

Or run without installing:

export ENTYRIX_API_KEY=your-api-key-here
npx entyrix-mcp

Client setup

Claude Desktop

Edit ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "entyrix": {
      "command": "npx",
      "args": ["-y", "entyrix-mcp"],
      "env": {
        "ENTYRIX_API_KEY": "your-api-key-here"
      }
    }
  }
}

Restart Claude Desktop. The 10 tools appear in the tools panel.

Claude Code

Register the server from any project (writes to ~/.claude.json):

claude mcp add entyrix --env ENTYRIX_API_KEY=your-api-key-here -- npx -y entyrix-mcp

Or add it manually to .mcp.json in your project root (checked in) / ~/.claude.json (global):

{
  "mcpServers": {
    "entyrix": {
      "command": "npx",
      "args": ["-y", "entyrix-mcp"],
      "env": {
        "ENTYRIX_API_KEY": "your-api-key-here"
      }
    }
  }
}

Cursor

Edit .cursor/mcp.json in your workspace (or ~/.cursor/mcp.json for global):

{
  "mcpServers": {
    "entyrix": {
      "command": "npx",
      "args": ["-y", "entyrix-mcp"],
      "env": {
        "ENTYRIX_API_KEY": "your-api-key-here"
      }
    }
  }
}

ChatGPT

ChatGPT does not consume MCP stdio servers directly today. Two integration paths:

1. Custom GPT Actions — expose Entyrix endpoints as OpenAPI actions. Sketch:

openapi: 3.1.0
info:
  title: Entyrix
  version: 0.1.0
servers:
  - url: https://entyrix.com/api/v1
paths:
  /companies/autocomplete:
    get:
      operationId: searchCompanies
      parameters:
        - name: q
          in: query
          required: true
          schema: { type: string }
        - name: country
          in: query
          schema: { type: string, minLength: 2, maxLength: 2 }
      responses:
        "200": { description: OK }
  /companies/{country}/{national_id}:
    get:
      operationId: lookupCompany
      parameters:
        - { name: country, in: path, required: true, schema: { type: string } }
        - { name: national_id, in: path, required: true, schema: { type: string } }
      responses:
        "200": { description: OK }
components:
  securitySchemes:
    BearerAuth:
      type: http
      scheme: bearer
security:
  - BearerAuth: []

Paste this into the Custom GPT builder, set the auth header, and the Entyrix endpoints become first-class GPT actions.

2. Connectors API (enterprise) — <https://platform.openai.com/docs/connectors> accepts MCP servers behind an HTTP wrapper; a small HTTP-to-stdio adapter is on the roadmap.

Development

git clone <repo>
cd entyrix-mcp
npm install
npm run build
npm test

Local stdio sanity-check (requires a real API key):

ENTYRIX_API_KEY=your-key node dist/index.js
# (stdin/stdout speaks MCP — wire it to a client to actually issue calls)

Quality gates

Every PR must pass:

npm run format
npm run lint
npx tsc --noEmit
npm test
