Hark Tech 3D Printing and Repair (UK)

Hark Tech MCP server: UK 3D printing prices for AI assistants

A remote Model Context Protocol server that lets an AI assistant price 3D prints with Hark Tech, a 3D printing service in Basingstoke, UK, and hand back a checkout link.

Endpoint: https://harktech.co.uk/mcp (streamable HTTP, no sign-in, no API key)

Share a link to your own STL, 3MF or STEP file and ask:

Price this in PETG, 3 copies: https://github.com/you/your-part/blob/main/bracket.stl

and you get a real price, postage and dispatch time, plus a checkout page with the file already priced in your basket. Nothing is ordered or charged until you pay on harktech.co.uk.

Add it to your assistant

Claude (claude.ai, Desktop or mobile): Settings, Connectors, Add custom connector, then paste https://harktech.co.uk/mcp.

Claude Code:

claude mcp add --transport http harktech https://harktech.co.uk/mcp

Other clients that support remote MCP servers (Cursor, VS Code, Gemini CLI, ChatGPT developer mode and others):

{

"mcpServers": { "harktech": { "type": "http", "url": "https://harktech.co.uk/mcp" } } }

Tools

Materials: PLA, PLA Matte, PLA Silk, PETG, TPU, ABS, ASA, PC, Nylon, PETG-CF and PA-CF. Prints are posted across the UK. Repairs are mail-in only (consoles, controllers, handhelds, laptops, TV and monitor boards, retro computers and circuit boards); the connector never books, orders or takes payment.

Example prompts

• "Here's my drone frame on Google Drive, how much in PETG-CF?"
• "Find a wall mount for a Dyson V15 and price 2 in PETG."
• "What's the cheapest way to get 20 of these cable clips printed and posted?"
• "My PS5 says no signal on the TV, what would Hark Tech charge to fix it?"
• "Where is my repair? Booking BK-1A2B3C4D, booked with sam@example.com."

How it works

This repo is the MCP layer only. Each tool is a thin wrapper over a public Hark Tech HTTP endpoint (documented in openapi.json); slicing and pricing happen on Hark Tech's side. The server runs stateless with JSON responses, and also serves an MCP Server Card and an AI Catalog for discovery.

Privacy: the server receives only what the assistant sends (a model or file link, material, quantity and speed) and does not see your conversation. See https://harktech.co.uk/privacy.html.

Running it yourself

You don't need to, the hosted endpoint is free to use. To read or run the code:

pip install -r requirements.txt

python run_local.py # stdio, for desktop MCP clients python run_local.py --http # streamable HTTP on 0.0.0.0:8003/mcp

Or with Docker:

docker build -t harktech-mcp .

docker run -i --rm harktech-mcp # stdio docker run --rm -p 8003:8003 harktech-mcp --http # HTTP

run_local.py points the tools at Hark Tech's public API (HARKTECH_BACKEND, default https://harktech.co.uk). Prices, checkout links and status lookups are the same as the hosted endpoint.
