Shieldmcp is a security middleware for Model Context Protocol (MCP) servers that provides tool access control, result sanitization, structured logging, and rate limiting without modifying the official SDK. It is intended for developers who need to secure and monitor MCP tool calls.

How to use Shieldmcp?

Apply the @secure_tool decorator to your MCP tools with optional parameters for allowed tools, sanitizer, user and session IDs, and rate limit configuration. Components like ToolAudit, ToolAccess, ToolSanitizer, and RateLimitConfig can also be used independently.
