Model Context Protocol # Grünig-SignTronic Catalog MCP Server A stateless, authless, read-only Model Context Protocol server that exposes the public Grünig-SignTronic screen-printing catalog — products, jobs, distributors, legal pages and news — to any MCP client or AI assistant, over one standard endpoint. [Get started](#setup) [Browse tools](#tools) Setup ## Connect a client The server speaks the Model Context Protocol over Streamable HTTP at a single endpoint. There is no API key and no account — point a client at the URL and its tools appear. MCP endpoint ``` https://mcp.grunig-signtronic.com/mcp ``` Streamable HTTP No authentication Read-only 1 Recommended ### Claude.ai connector Add it as a custom connector in Claude. 1. Open Settings → Connectors. 2. Click Add custom connector. 3. Paste the endpoint shown above; leave authentication empty. 4. Save, enable it in a chat, then ask about the catalog. Use the MCP endpoint shown above 2 ### ChatGPT Add it as a custom connector in ChatGPT (Plus, Pro, Team or Enterprise). 1. Open Settings → Connectors. 2. Click Create and choose a custom (MCP) connector. 3. Paste the endpoint shown above as the server URL; set authentication to none. 4. Save, enable it in a chat, then ask about the catalog. Use the MCP endpoint shown above 3 ### MCP Inspector Inspect and call tools directly from a terminal. 1. Run the command below. 2. Choose the Streamable HTTP transport. 3. Enter the endpoint and click Connect. 4. Use List Tools / Call Tool to explore. Run ``` npx @modelcontextprotocol/inspector ``` ### Or let your assistant set it up Paste this into Claude, ChatGPT or any MCP-aware assistant to add the server and try it in one step: Setup prompt ``` Add the remote MCP server "Grünig-SignTronic Catalog" at https://mcp.grunig-signtronic.com/mcp (Model Context Protocol over Streamable HTTP, no authentication) to my MCP client, then list its tools and run search_products with query "coating" to confirm it works. ``` ### Call a tool directly (curl) Every request is a single JSON-RPC `POST`. This searches the product catalog: Search products ``` curl -s https://mcp.grunig-signtronic.com/mcp -H 'content-type: application/json' -H 'accept: application/json, text/event-stream' -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"search_products","arguments":{"query":"coating","lang":"en"}}}' ``` Reference ## Tools Every entity follows a uniform list / search + get shape: list and search tools return compact summaries, get\_\* tools return full detail. All tools are read-only, and every tool except ping takes a lang of “en” or “de”. This reference is generated from the server's own tool definitions, so it always matches what the endpoint exposes. ### ping Ping Liveness check — returns 'pong' and the active environment. Takes no arguments. **Returns:** `A short text string, e.g. pong (production).` Example call Example call ``` { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "ping", "arguments": {} } } ``` ### search\_products Search products Search the active Grünig-SignTronic product catalog in the requested language. The query is a case-insensitive substring matched across all product text — name, short and full description, features, benefits, applications and specifications — so model numbers and technical terms (e.g. "1270", "UV-LED") match too. Optionally filter by category (see list\_categories for valid slugs). Returns compact product summaries (slug, name, short description, category, canonical URL). Use get\_product for full detail. | Parameter | Type | Req. | Description | | --------- | -------------- | -------- | -------------------------------------------------- | | query | string (1–200) | required | Case-insensitive search term. | | lang | "en" \| "de" | required | Response language for the catalog content. | | limit | integer (1–50) | optional | Max results. Default 10. | | category | string (≤100) | optional | Category slug to filter by (see list\_categories). | **Returns:** `{ count, results: [{ slug, name, shortDescription, category, url }] }.` Example call Example call ``` { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "search_products", "arguments": { "query": "coating", "lang": "en" } } } ``` ### get\_product Get product Return the full detail of a single active product, resolved by slug (preferred) or id, in the requested language: descriptions, features, benefits, applications, specifications, documents and related-product slugs. | Parameter | Type | Req. | Description | | --------- | ------------- | -------- | ------------------------------------------ | | slug | string (≤200) | optional | Product slug. Provide slug or id. | | id | string (≤100) | optional | Product id.

Example call Example call ``` { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "get_product", "arguments": { "slug": "g-202", "lang": "en" } } } ``` ### list\_categories List categories List all active product categories in the requested language (slug, name, description). Use a returned slug to filter search\_products. | Parameter | Type | Req. | Description | | --------- | --------------- | -------- | ------------------------------------------ | | lang | "en" \| "de" | required | Response language for the catalog content. | | limit | integer (1–200) | optional | Max results.

The catalog is refreshed whenever the website publishes; the server never writes. ### Security The endpoint is authless, read-only and stateless. It exposes no secrets, no writes and no personal data beyond what is already public on the website. ### Transport Model Context Protocol over Streamable HTTP. Requests are plain JSON-RPC over POST; responses are edge-cached where safe. ```json {"@context":"https://schema.org","@type":"WebSite","@id":"https://mcp.grunig-signtronic.com/#website","url":"https://mcp.grunig-signtronic.com","name":"Grünig-SignTronic MCP","description":"Connect any MCP client to the public Grünig-SignTronic screen-printing catalog: products, jobs, distributors, legal pages and news.
