About
mcp-yoshi is a plugin bundle for AI coding tools published by aliksir. Marketplaces we read that list it: 1 (Claude Code: claude-plugins-community). We first saw it on 2026-10-11 and have recorded no change since. As of our marketplace pass on 2026-10-12.
Real-time security filter for MCP tool communications. Works as a Claude Code hook to inspect all data sent to and received from MCP servers. Detects prompt injection, API key leakage, tool poisoning, ASCII smuggling, SSRF, Base64-encoded payloads, and Rug Pull attacks. Provides PASS/WARN/BLOCK decisions with per-server configuration, allowlisting, and logging. Zero dependencies, ~60ms latency.

Is this your plugin?
Prove you maintain it with a file in its repository, a file on your domain or a DNS record. You get alerts when a marketplace lists it, drops it, changes its verified mark or what it asks for, and can put its remote endpoint on monitoring as a web service.
Data comes from the public marketplace file https://github.com/anthropics/claude-plugins-community/blob/HEAD/.claude-plugin/marketplace.json. Figures come from our own regular passes over the marketplaces, last read on . We publish no contact details for plugin publishers.
