List all configured source directories with indexing statistics.
AI agents call list_sources to retrieve information from MemoryMesh without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays configuration and statistics about source directories. It performs no data modification, deletion, code execution, or financial operations. The action is a straightforward read/query operation that returns information about the system's indexing state.
From the tool's definition Tool name 'list_sources' and description 'List all configured source directories with indexing statistics' indicate a retrieval operation that queries indexing metadata without modifying data.
Attacks that exploit this kind of access
List all configured source directories with indexing statistics. It is categorised as a Read tool in the MemoryMesh MCP Server, which means it retrieves data without modifying state.
Register the MemoryMesh MCP server in PolicyLayer and add a rule for list_sources: 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 MemoryMesh. Nothing to install.
list_sources 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_sources 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_sources. 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_sources is provided by the MemoryMesh MCP server (kilhubprojects/memory-mesh). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
