MCP Proxy Guardrail
A proxy-layer security mechanism positioned between an AI agent and an MCP server, used to monitor and enforce tool invocation policies centrally, covering tool permissions, data masking and request rate limits.
Timeline (last 90 days)
MCP Proxy Guardrail sits between the agent and MCP servers, giving a unified view of all tool call requests and returned data without having to intrude into the internals of each MCP server's implementation.
In the demo, disabled tools are completely invisible to the agent rather than simply having their calls rejected.
In the Columns settings, masking can be applied to specific fields, for example email masked as u***@example.com.
In the Limits settings, you can limit the number of requests and configure a progressive response strategy from Warn to Block.
The progressive response strategy issues a warning first when an Agent approaches the threshold, and only triggers blocking when it continues to cross the line, reducing task interruptions caused by transient traffic fluctuations.
After saving, the new guardrail is immediately active and takes effect alongside other existing guardrails.
