Security Report
This is a thin, unauthenticated MCP proxy that forwards five tools to the Hark Tech backend at harktech.co.uk, with no local file, shell, or credential access. The main concerns are intentional public exposure, the quote_my_file tool creating saved baskets on the backend, trust in forwarded client IP headers, and DNS-rebinding protection being disabled for a server documented to run locally. Permissions match the stated purpose, so the score remains in the good range. Supply chain analysis found 3 known vulnerabilities in dependencies (1 critical, 2 high severity).

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):

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. |
Materials: PLA, PLA Matte, PLA Silk, PETG, TPU, ABS, ASA, PC, Nylon, PETG-CF and PA-CF. Prints are posted across the UK.
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?"
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
HARKTECH_BACKEND=https://harktech.co.uk python server.py
It listens on 127.0.0.1:8003/mcp.
