Reads a file from the directories. Please specify if it is a Artifact or if its a note.
AI agents call read to retrieve information from MCP Developer Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves file contents without side effects. It is a simple read operation that does not create, modify, execute, or delete data. The low severity reflects that an AI agent using this tool can only access existing files, not alter system state or trigger operations.
From the tool's definition Tool name is 'read' and description explicitly states 'Reads a file from the directories' with no mention of modification, execution, or deletion.
Attacks that exploit this kind of access
Reads a file from the directories. Please specify if it is a Artifact or if its a note. It is categorised as a Read tool in the MCP Developer Server MCP Server, which means it retrieves data without modifying state.
Register the MCP Developer Server MCP server in PolicyLayer and add a rule for read: 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 MCP Developer Server. Nothing to install.
read 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 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. 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 is provided by the MCP Developer Server MCP server (ra86-dev/mcpdockershell). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
