Generate a summary of a Python or Markdown file.
AI agents call summary to retrieve information from MCP File System Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only reads file content to generate a summary; it performs no write, deletion, execution, or financial operations. The action is informational and has no side effects on the file system or data state.
From the tool's definition Tool name 'summary' and description states it 'Generate a summary of a Python or Markdown file', which is a read-only operation that retrieves and analyzes file content without modification.
Attacks that exploit this kind of access

Register the MCP File System Server MCP server in PolicyLayer and add a rule for summary: 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 MCP File System Server. Nothing to install.
summary 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 summary 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 summary. 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.
summary is provided by the MCP File System Server MCP server (kvas-it/mcp-server-fs). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
