Koi bhi file padhna
AI agents call file_read to retrieve information from Universal Dev MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries file data with no side effects. It performs a read operation on the filesystem, matching the Read category definition. Severity is low because unauthorized file reads pose limited immediate risk compared to write/delete/execute operations, though context (sensitive files) could elevate this in specific scenarios.
From the tool's definition Tool name 'file_read' and description 'Koi bhi file padhna' (Hindi: 'read any file') both indicate retrieval of file contents without modification.
Attacks that exploit this kind of access
Koi bhi file padhna. It is categorised as a Read tool in the Universal Dev MCP MCP Server, which means it retrieves data without modifying state.
Register the Universal Dev MCP server in PolicyLayer and add a rule for file_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 Universal Dev MCP. Nothing to install.
file_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 file_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 file_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.
file_read is provided by the Universal Dev MCP server (kallusuvaidyam/universal_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
