## 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 2026-11-05.

- **Endpoint Security**: 46/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not yet verified: we couldn't confirm whether this endpoint requires it.
  - HTTPS enforcement could not be verified: the plaintext port redirected somewhere other than https, so enforcement is unproven.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 0/100
  - Transport check failed: declared streamable-http, but the endpoint redirected instead of responding directly.
- **Schema Quality & AI Usability**: 0/100
  - Schema not yet verified: we couldn't read the endpoint's schema, or could read only part of its tool list.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 0/100
  - Tool coverage not yet verified: we couldn't read the endpoint's tools, or could read only part of the list.
- **Tool Safety**: 0/100
  - Tool safety not yet verified: we couldn't read the endpoint's tools, or could read only part of the list.
- **Capabilities**: 0/100
  - Capabilities not yet verified: we couldn't read the endpoint's capabilities.

**Unverified: 5 categories.** Categories scored 0 because we could not verify them: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.

## Common questions

### What is the Twice Commerce MCP by usefulapi server?

Twice Commerce MCP by usefulapi is listed in the public MCP registry as io.usefulapi/twice-commerce. Read orders, customers, catalog, stock and availability; add order comments in Twice Commerce. This page covers its hosted endpoint (https://twice-commerce.usefulapi.io/mcp).

### Is the Twice Commerce MCP by usefulapi server safe to use?

Twice Commerce MCP by usefulapi scores 18 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 Twice Commerce MCP by usefulapi server expose?

Twice Commerce MCP by usefulapi exposes 20 tools: twicecommerce_get_merchant, twicecommerce_list_service_locations, twicecommerce_list_taxes, twicecommerce_list_tags, twicecommerce_list_orders, and 15 more. Their descriptions and schemas cost roughly 1,442 tokens of context every time the server is loaded.

### Does the Twice Commerce MCP by usefulapi server require authentication?

Its publisher declares no required credentials for Twice Commerce MCP by usefulapi. We have not been able to confirm that against the live endpoint, and a server can require authorisation without declaring it here.

### Is the Twice Commerce MCP by usefulapi server still maintained?

Twice Commerce MCP by usefulapi is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What did VerifyMCP test on the Twice Commerce MCP by usefulapi server?

VerifyMCP ran 4 checks on Twice Commerce MCP by usefulapi, covering TLS certificate, HSTS header, DNSSEC and Transport. 7 items could not be completed, a gap on our side rather than a finding about Twice Commerce MCP by usefulapi: Authorization, HTTPS, Schema quality, Stability and 3 more. 5 categories score 0 for that reason, because we only credit what we can confirm. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
