MCP tools · 2 exposed · ~350 tokens

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 did VerifyMCP test on the Universal Screenshot MCP server?

VerifyMCP ran 16 checks on Universal Screenshot MCP, covering Malware scan, Known CVEs, Install scripts, Dependency health and 12 more.
