## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-17.

- **Endpoint Security**: 97/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation is enforced on tool calls, advertised via RFC 9728 protected-resource metadata. Discovery is public, which costs nothing: no tool can be invoked without a token.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 71/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 1957 tokens (~97/item across 20 items; 20 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 17/100
  - Stability observed for 5 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 81/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 42% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 20 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 20 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

This tool does NOT create an order; it returns part_price / total / order_url. Output is desensitized (no unit prices).

- `parts` (array, required): One or more part lines. Each line is priced independently.

### `search_materials` (~280 tokens)

Use to resolve a user's material description (industry grade name like 'PA12', a colloquial term like 'nylon', a Chinese term, or a vague description) into concrete materials.csv entries. Unlike compare_materials/find_equivalent_materials (which need an exact known ID), this tool accepts messy input and returns a ranked list of candidates — use it as the first step when you don't already know the exact material_id. If multiple candidates come back, ask the user to pick one rather than guessing. Optionally narrow by category_hint (Plastic/Metal/Rubber/Resin/Powder Metals/Powder Polymers) or process_filter (e.g. 'Selective Laser Sintering', 'SLS', 'Injection Molding') when the context already implies a manufacturing process.

Input parameters:

- `category_hint` (string): Optional coarse category filter matched against Material_Category(L1)/Material_Sub-Category(L2).
- `limit` (number): Max candidates to return. Defaults to 10.
- `process_filter` (string): Optional manufacturing process substring filter matched against Compatible_Processes, e.g. 'SLS', 'Selective Laser Sintering', 'Injection Molding'.
- `query` (string, required): User's material description, ideally already normalized to English (e.g. 'PA12', 'nylon', '316 stainless steel').

## Common questions

### What is the MechanoFab MCP server?

MechanoFab is an MCP server listed in the public MCP registry as com.mechanofab/mechanofab. Manufacturing capability graph for AI agents: materials, processes, tolerances, and instant quotes. This page covers its hosted endpoint (https://mcp.mechanofab.com/mcp).

### Is the MechanoFab MCP server safe to use?

MechanoFab scores 80 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the MechanoFab MCP server expose?

MechanoFab exposes 20 tools: calculate_part_mass, check_equipment_capability, check_material_environment_compatibility, check_service_temperature, compare_equipment, and 15 more. Their descriptions and schemas cost roughly 1,957 tokens of context every time the server is loaded.

### Does the MechanoFab MCP server require authentication?

Yes. MechanoFab asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything.

### Is the MechanoFab MCP server still maintained?

MechanoFab is still listed as active in the MCP registry. We last reached this channel on 17 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
