Review a code chunk against a plan step with AST-localized context and pre-flight checks.
AI agents call review_code_chunk to retrieve information from Codeviewer without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Code review is an analytical read operation that examines code structure and provides feedback. While it generates patch suggestions, these are recommendations only (not automatically applied modifications), making this a Read category tool. The AST-aware nature confirms static analysis rather than dynamic execution.
From the tool's definition The tool performs code review analysis and returns structured feedback with 'verdicts and patch suggestions' - it reads and analyzes code without modifying, executing, or deleting anything.
Attacks that exploit this kind of access
Review a code chunk against a plan step with AST-localized context and pre-flight checks. It is categorised as a Read tool in the Codeviewer MCP Server, which means it retrieves data without modifying state.
Register the Codeviewer MCP server in PolicyLayer and add a rule for review_code_chunk: 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 Codeviewer. Nothing to install.
review_code_chunk 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 review_code_chunk 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 review_code_chunk. 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.
review_code_chunk is provided by the Codeviewer MCP server (master0ffate/codeviewer-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
