MCP Snitch

MCP Snitch is a real-time security monitoring and policy enforcement layer for Model Context Protocol (MCP) tools. It is designed to give teams precise visibility and control over how AI agents interact with external tools and APIs, with a particular focus on protecting sensitive credentials and preventing unauthorized operations. By sitting between your MCP server and tools, MCP Snitch continuously inspects, validates, and logs tool calls to maintain a secure and auditable environment.

Key capabilities include granular whitelisting of tool calls, parameters, and destinations, allowing you to define exactly which tools can be invoked, under what conditions, and with which inputs. MCP Snitch can detect and block attempts to exfiltrate API keys or other secrets, helping prevent prompt injection and data leakage attacks. It offers detailed, real-time logging and dashboards so security and engineering teams can review historical tool usage, investigate anomalies, and enforce compliance requirements. Configuration is typically handled through clear policies and rules, enabling teams to standardize security controls across multiple MCP tools and environments.
