## 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 2026-11-04.

- **Endpoint Security**: 57/100
  - 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 is enforced; there's no plaintext access path.
  - HSTS not yet verified: we couldn't read the response headers to check for it.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 0/100
  - Transport check failed: declared streamable-http, but we couldn't connect to verify it.
- **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 PNG.now MCP Server server?

PNG.now MCP Server is listed in the public MCP registry as io.github.chrisyau83/png-now. Compress PNG images and convert them to or from popular image and document formats. This page covers its hosted endpoint (https://png.now/mcp).

### Is the PNG.now MCP Server server safe to use?

PNG.now MCP Server scores 0 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 PNG.now MCP Server server expose?

PNG.now MCP Server exposes 4 tools: list_converters, convert_image_url, get_conversion_status, get_api_usage. Their descriptions and schemas cost roughly 226 tokens of context every time the server is loaded.

### Does the PNG.now MCP Server server require authentication?

Its publisher declares that PNG.now MCP Server requires credentials, so you will need to authorise it in your MCP client. We have not been able to confirm that against the live endpoint.

### Is the PNG.now MCP Server server still maintained?

PNG.now MCP Server has been unreachable for long enough that we treat it as dead, and its score is pinned to zero. We last reached this channel on 28 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
