Count total lines, code lines, comment lines, and blank lines.
AI agents call count_lines_of_code to retrieve information from Claude File Management Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a passive analysis operation that retrieves and reports statistics about file content. It has no side effects, does not execute code, does not modify data, and does not create risk of data loss or unauthorized operations. The worst-case misuse would be information gathering, which poses minimal risk.
From the tool's definition The tool 'count_lines_of_code' performs a purely informational analysis that counts and reports metrics (total lines, code lines, comment lines, blank lines) without modifying, executing, or deleting any data.
Attacks that exploit this kind of access
Count total lines, code lines, comment lines, and blank lines. It is categorised as a Read tool in the Claude File Management Server MCP Server, which means it retrieves data without modifying state.
Register the Claude File Management Server MCP server in PolicyLayer and add a rule for count_lines_of_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 Claude File Management Server. Nothing to install.
count_lines_of_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 count_lines_of_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 count_lines_of_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.
count_lines_of_code is provided by the Claude File Management Server MCP server (vipin1000/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
