Read values from multiple JSON files at a specified path using dot notation. Returns a map of file paths to values.
AI agents call read_multiple_json_values to retrieve information from JSON Editor MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves data from JSON files using dot notation paths and returns the values without any side effects. It performs a read-only operation with no capacity to modify, delete, or execute code. The low severity reflects minimal risk even if misused by an agent, as it can only expose existing data.
From the tool's definition Tool name explicitly contains 'read', and description states it 'Read values from multiple JSON files at a specified path'. Returns data without modification.
Attacks that exploit this kind of access
Read values from multiple JSON files at a specified path using dot notation. Returns a map of file paths to values. It is categorised as a Read tool in the JSON Editor MCP MCP Server, which means it retrieves data without modifying state.
Register the JSON Editor MCP server in PolicyLayer and add a rule for read_multiple_json_values: 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 JSON Editor MCP. Nothing to install.
read_multiple_json_values 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 read_multiple_json_values 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 read_multiple_json_values. 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.
read_multiple_json_values is provided by the JSON Editor MCP server (peternagy1332/json-editor-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
