SENTINEL

Overview

SENTINEL is a Model Context Protocol (MCP) server: Pre-execution safety oracle for AI agents. Screens Base contracts, simulates sells, pays via x402. In practice that means any MCP-compatible AI assistant can call SENTINEL's tools directly — the model decides when to use them in a conversation or agent run.

It runs locally: the Python package sentinel-mcp (via uvx) speaks MCP over stdio on your machine. Configuration happens through environment variables — you'll need AGENT_WALLET_PRIVATE_KEY. The current release is v1.0.1.

SENTINEL is listed under AI & Agents on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
