Hark Tech 3D Printing and Repair (UK)

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

MCP Registry License: MIT

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

Tools

Tool

What it does

quote_my_file

Prices your own STL, 3MF or STEP file from a share link (Google Drive or OneDrive "anyone with the link", Dropbox, GitHub, Discord attachment) and returns a checkout_url with it priced in your basket.

search_models

Searches Printables and Thingiverse models whose licence allows commercial printing.

get_quote

Live price, postage, dispatch time, batch discounts and order link for a catalogue model, material and quantity.

get_upload_page

Where to upload a file when there is no share link.

get_service_info

Order minimums, postage, lead times, batch discounts, materials and licence policy.

search_repair_services

Matches a device and fault to Hark Tech's published mail-in repair services: fixed price or assessment fee, 5 to 7 working day turnaround, warranty and a booking link.

get_repair_service_info

Repair policies: the mail-in process, what the £40 assessment covers, what is not offered, warranty, return postage, trade terms and privacy.

get_order_status

Progress of one 3D print order for the customer who placed it (order reference plus the email it was placed with).

get_repair_status

Progress of one repair booking or enquiry for its customer (reference plus the email it was booked with). Status, dates and return tracking only.

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.

    A4.2/5.0

    Scored across 9 tools

    Disambiguation5/5

    Each tool targets a distinct resource or action: catalogue model search, catalogue model quote, user-file quote, upload page, printing service info, repair service search, repair policy info, print order status, and repair status. The two quoting tools are clearly separated by input type (model_link vs file_url), and the two status tools are separated by order vs repair. No overlapping or indistinguishable tools are present.

    Naming Consistency5/5

    All names use snake_case and follow a predictable verb_noun pattern such as search_models, get_quote, quote_my_file, get_service_info, search_repair_services, and get_order_status. There are no mixed conventions or vague standalone verbs.

    Tool Count5/5

    Nine tools is well-scoped for a combined 3D printing and repair business. Each tool covers a meaningful part of the customer journey without excessive granularity.

    Completeness4/5

    The surface covers search, quoting, service information, and status checking for both 3D printing and repairs. Order placement and repair booking are handled via external URLs rather than dedicated tools, which is a minor gap but workable for an agent.
