Parse code file into semantic chunks (functions, classes, methods) for better RAG retrieval.
AI agents call chunk_code to retrieve information from MidOS - MCP Community Library without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs static analysis and semantic extraction on code for information retrieval purposes. It reads and analyzes code structure but does not execute code, modify files, delete data, or trigger external operations. The output is structured metadata for downstream search/indexing, making it a Read-category tool with low severity risk even in misuse scenarios.
From the tool's definition Tool description states 'Parse code file into semantic chunks' — a parsing/analysis operation with no modification of data. The action is retrieval-oriented ('for better RAG retrieval'), with no side effects or data mutation.
Attacks that exploit this kind of access
Parse code file into semantic chunks (functions, classes, methods) for better RAG retrieval. It is categorised as a Read tool in the MidOS - MCP Community Library MCP Server, which means it retrieves data without modifying state.
Register the MidOS - MCP Community Library MCP server in PolicyLayer and add a rule for chunk_code: 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 MidOS - MCP Community Library. Nothing to install.
chunk_code 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 chunk_code 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 chunk_code. 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.
chunk_code is provided by the MidOS - MCP Community Library MCP server (midos-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
