Dead
Every channel of this server has been unreachable for long enough to be marked dead. Its trust score is pinned to 0 and does not recover automatically: even once the server responds again it stays dead until it is manually reinstated.
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. How we score → Why this is hard to score →
Endpoint Security57
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not yet verified: we couldn't confirm whether this endpoint requires it. View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS not yet verified: we couldn't read the response headers to check for it. View diagnostics → Unverified
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability0
- Transport check failed: declared streamable-http, but we couldn't connect to verify it. See how to fix → View diagnostics → Fail
Schema Quality & AI Usability0
- Schema not yet verified: we couldn't read the endpoint's schema, or could read only part of its tool list.Unverified
Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage0
- Tool coverage not yet verified: we couldn't read the endpoint's tools, or could read only part of the list.Unverified
Tool Safety0
- Tool safety not yet verified: we couldn't read the endpoint's tools, or could read only part of the list.Unverified
Capabilities0
- Capabilities not yet verified: we couldn't read the endpoint's capabilities.Unverified
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.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

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.
