🔌 MCP Server9hannahnine-jpg
Runtime governance for MCP tool calls, preventing prompt injection and unauthorized capability abuse in AI agents.
arc-gate-mcp addresses the critical security challenges inherent in integrating external tools via the Model Context Protocol. As AI agents gain the ability to execute arbitrary code or interact with sensitive APIs, the risk of prompt injection and unauthorized tool usage increases significantly. This server functions as a gatekeeper, sitting between the MCP host and the tool execution environment. It provides a structured way to enforce runtime governance, ensuring that every tool call is scrutinized against security policies before execution. Key features include real-time monitoring of tool requests, automated filtering of malicious payloads, and the ability to define granular permissions for specific tools. By implementing this layer, developers can mitigate the risks of indirect prompt injection and ensure that their agents do not exceed their intended operational scope. It is designed for seamless integration into existing MCP workflows, requiring minimal configuration to add a robust layer of defense to any AI-powered system.
