### Description (declared)

Checks what an agent tool declares it can do — an MCP server's tools/list, a skill's text — for tool poisoning, hidden instructions, exfiltration and rug-pull patterns, then signs the verdict with a P-256 key and anchors it on Monad, where the contract verifies that signature through the P256VERIFY precompile. Every verdict is pinned to the hash of the exact manifest it covers, so a tool that changes after it was cleared no longer matches. A survey of the 40 most-downloaded MCP servers on npm is published with it. Local MCP server for agents: npx -y monadguard-mcp.
