Read a small UTF-8 text file. Argument: path (required)
AI agents call read_text to retrieve information from Aurora-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 a file system without creating, modifying, deleting, or executing operations. It is a straightforward read operation with minimal blast radius—the only risk would be information disclosure if sensitive data is stored in readable text files, but that is an environmental concern rather than a capability of the tool itself.
From the tool's definition Tool name 'read_text' and description 'Read a small UTF-8 text file' explicitly indicate retrieval of file contents with no modification or side effects.
Attacks that exploit this kind of access
Read a small UTF-8 text file. Argument: path (required). It is categorised as a Read tool in the Aurora-MCP MCP Server, which means it retrieves data without modifying state.
Register the Aurora- MCP server in PolicyLayer and add a rule for read_text: 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 Aurora-MCP. Nothing to install.
read_text 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_text 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_text. 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_text is provided by the Aurora- MCP server (ndaniel/aurora-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
