## 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**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - 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**: 62/100
  - AI-judged instruction clarity (fair).
  - Tool/resource definitions use about 828 tokens (~92/item across 9 items; 9 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 3/100
  - Stability observed for 1 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 72/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 17% 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 9 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 10 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.

## Common questions

### What is the Print and Vector QA MCP server?

Print and Vector QA is an MCP server listed in the public MCP registry as io.github.tohaa28/print-vector-qa. Seven print/vector QA APIs: free samples, MCP discovery and x402 requests from 0.02 USDC. This page covers its hosted endpoint (https://first-ruble-agent.tohaa28.workers.dev/mcp).

### Is the Print and Vector QA MCP server safe to use?

Print and Vector QA scores 63 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 Print and Vector QA MCP server expose?

Print and Vector QA exposes 9 tools: list_print_qa_services, get_print_qa_sample, prepare_preflight, prepare_printcheck, prepare_curve_clearance, and 4 more. Their descriptions and schemas cost roughly 781 tokens of context every time the server is loaded.

### Does the Print and Vector QA MCP server require authentication?

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

### Is the Print and Vector QA MCP server still maintained?

Print and Vector QA 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.
