Toggle boolean value at path.
AI agents call json_toggle to retrieve information from Amazon MQ MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The description lacks clarity on whether this modifies data persistently or operates on a temporary object. 'Toggle' typically implies a reversible state change (suggesting Write), but without explicit confirmation that it persists changes or what the downstream effects are, and given the minimal context provided, this appears to be a low-impact utility.
From the tool's definition Tool name 'json_toggle' and description 'Toggle boolean value at path' suggest a simple operation on a JSON structure, but the description is uninformative about actual effects.
Attacks that exploit this kind of access
Toggle boolean value at path. It is categorised as a Read tool in the Amazon MQ MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Amazon MQ MCP Server MCP server in PolicyLayer and add a rule for json_toggle: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Amazon MQ MCP Server. Nothing to install.
json_toggle is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the json_toggle rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for json_toggle. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
json_toggle is provided by the Amazon MQ MCP Server MCP server (awslabs.amazon-mq-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
