Read a text-like file relative to repo root, RBAC-enforced by folder domain.
AI agents call read_file to retrieve information from FinRAG-MCP 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 with role-based access control enforced. It has no side effects—it queries and returns data only. The RBAC mechanism mitigates risk by restricting visibility to authorized roles. Even if misused by an agent, the worst outcome is reading data the user's role permits, which is a Read-category risk.
From the tool's definition Tool name 'read_file' and description explicitly states 'Read a text-like file' with access control ('RBAC-enforced'). Returns data without modification or deletion.

Attacks that exploit this kind of access
Read a text-like file relative to repo root, RBAC-enforced by folder domain. It is categorised as a Read tool in the FinRAG-MCP MCP Server, which means it retrieves data without modifying state.
Register the FinRAG- MCP server in PolicyLayer and add a rule for read_file: 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 FinRAG-MCP. Nothing to install.
read_file 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_file 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_file. 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_file is provided by the FinRAG- MCP server (nithishkaranam2002/finrag--mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
