## 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 2026-09-20.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 2 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - 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).
  - Context-footprint check failed: tool/resource definitions use about 357 tokens (~178/item across 2 items; 2 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 90/100
  - Stability observed for 27 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 95/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 86% 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 2 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 2 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.

## MCP tools (2)

### `find_manufacturer` (~134 tokens)

Search the Harness Atlas directory of wire-harness and cable-assembly manufacturers. Filter by country, industry served, process capability, or name. Returns listed manufacturer profiles (location, website, industries, capabilities).

Input parameters:

- `capability` (string): Required process capability, e.g. 'hv_capable', 'ultrasonic_welding', 'ipc_whma_620'.
- `country` (string): HQ country, e.g. 'Germany', 'Poland', 'China'.
- `industry` (string): Industry the manufacturer serves.
- `limit` (integer)
- `name` (string): Partial company name to match.

### `find_alternative` (~223 tokens)

Cross-reference a wire-harness component part number (connectors, terminals, seals, cable protection) against the XrefBase equivalence graph. Results are grouped by how strong the relationship is, and the groups are not interchangeable: `verified_replacements` are corroborated drop-in or manufacturer-superseded parts; `functional_equivalents` do the same job but need engineering review; `same_series` and `variants` are the same family in a different configuration and are NOT substitutes; `mates_with` is the counterpart connector the part plugs into, which is specifically not a substitute for it. Every claim carries a confidence level and, where one exists, a public source URL.

Input parameters:

- `manufacturer` (string): Optional original manufacturer name. Accepts known aliases ('TE', 'H+S'). Disambiguates when one MPN exists under several manufacturers.
- `part_number` (string, required): Manufacturer part number to cross-reference. Punctuation and case are normalised, so '1-967616-1' and '19676161' both match.

## Common questions

### What is the Harness Atlas MCP server?

Harness Atlas is an MCP server listed in the public MCP registry as io.github.pawel-kowalczyk/harness-atlas. Search 500+ wire-harness & cable-assembly manufacturers by country, industry, and capability. This page covers its hosted endpoint (https://harnessatlas.com/api/mcp).

### Is the Harness Atlas MCP server safe to use?

Harness Atlas scores 78 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 Harness Atlas MCP server expose?

Harness Atlas exposes 2 tools: find_manufacturer, find_alternative. Their descriptions and schemas cost roughly 357 tokens of context every time the server is loaded.

### Does the Harness Atlas MCP server require authentication?

No. We connected to Harness Atlas without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the Harness Atlas MCP server still maintained?

Harness Atlas is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
