Solidity static analyzer you can talk to. MCP integration for Claude Code, Cursor, and Windsurf.
개요
Solidity static analyzer you can talk to Ask your AI assistant to audit your contracts. Get explained results. Weasel skills activate. Your AI runs analysis, writes PoCs, formats reports, and more. - — 9 specialized skills for Claude Code (PoC writing, report formatting, gas optimization, and more) - — Parallel Rust analysis, instant MCP responses - — Works with Claude Code, Cursor, Windsurf, OpenAI Codex, Gemini CLI, and any MCP-compatible tool - — Vulnerabilities, gas optimizations, and code quality checks - — Automatically configures for Foundry, Hardhat, and Truffle projects Update anytime with weaselup. Use weaselup --nightly for latest dev build. For users, install the Weasel plugin for intelligent skills: — Claude knows how to analyze Solidity, write PoCs in Foundry/Hardhat, format audit reports, and more. The weasel prefix ensures skills only activate when you want them. To update the plugin, run /plugin update weasel in Claude Code.

Weasel
Solidity static analyzer you can talk to
Ask your AI assistant to audit your contracts. Get explained results.
# 1. Install weasel
curl -L https://raw.githubusercontent.com/slvDev/weasel/main/weaselup/install | bash
# 2. Add to your AI tool:
# Claude Code (recommended - MCP + skills)
/plugin marketplace add slvDev/weasel
/plugin install weasel
# MCP only for Claude Code, Cursor, Windsurf, Codex, Gemini
weasel mcp add
Now just say weasel :
“weasel analyze my contracts”
“weasel poc for this reentrancy bug”
“weasel report this finding”
“weasel explain this function”
Weasel skills activate. Your AI runs analysis, writes PoCs, formats reports, and more.

Why Weasel?
| Weasel | Other Analyzers | |
|---|---|---|
| AI Integration | Native skills + MCP | Copy-paste output to ChatGPT |
| Setup | plugin install / mcp add |
Manual config, scripts |
| Workflow | “weasel poc for this bug” | Read reports, search fixes |
| Context | AI knows Solidity security patterns | Context lost between tools |
| Speed | Parallel Rust analysis | Often single-threaded |
Installation
curl -L https://raw.githubusercontent.com/slvDev/weasel/main/weaselup/install | bash
Update anytime with weaselup. Use weaselup --nightly for latest dev build.
Claude Code Integration
For Claude Code users, install the Weasel plugin for intelligent skills:
/plugin marketplace add slvDev/weasel
/plugin install weasel
Use weasel prefix to activate skills:
