AI agents call get_codebase_context to retrieve information from Omni Rag 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 directory structure/metadata for analysis purposes. It has no side effects—it does not modify, delete, or execute anything. While deprecated, its function remains a straightforward information retrieval operation, placing it firmly in the Read category with low severity.
From the tool's definition Tool description states it 'Get[s] directory overview' and is marked as a read operation that retrieves structural information about a directory without modifying it.
Attacks that exploit this kind of access
[Deprecated: use 'get_context'] Get directory overview. It is categorised as a Read tool in the Omni Rag MCP Server, which means it retrieves data without modifying state.
Register the Omni Rag MCP server in PolicyLayer and add a rule for get_codebase_context: 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 Omni Rag. Nothing to install.
get_codebase_context 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 get_codebase_context 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 get_codebase_context. 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.
get_codebase_context is provided by the Omni Rag MCP server (suyash2013/codebase-rag-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
