List all files within a specific project
AI agents call list_project_files to retrieve information from Memory Bank without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool queries and returns a list of files, which is a read-only operation. It has no ability to modify, delete, or execute code. The blast radius is minimal as it only exposes file listings that are likely already known to authorized project members.
From the tool's definition Tool name is 'list_project_files' and description states 'List all files within a specific project' — this is a retrieval operation with no side effects.
Attacks that exploit this kind of access
List all files within a specific project. It is categorised as a Read tool in the Memory Bank MCP Server, which means it retrieves data without modifying state.
Register the Memory Bank MCP server in PolicyLayer and add a rule for list_project_files: 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 Memory Bank. Nothing to install.
list_project_files 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 list_project_files 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 list_project_files. 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.
list_project_files is provided by the Memory Bank MCP server (@allpepper/memory-bank-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
