List all your saved project sessions
AI agents call list_sessions to retrieve information from Prompt Architect without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves and displays metadata about existing project sessions. It performs a read-only query operation without creating, modifying, deleting, or executing any actions. The blast radius of misuse is minimal—exposure of session names or metadata poses limited risk compared to other severity categories.
From the tool's definition Tool name 'list_sessions' and description 'List all your saved project sessions' indicate a retrieval operation with no modification or side effects.
Attacks that exploit this kind of access
List all your saved project sessions. It is categorised as a Read tool in the Prompt Architect MCP Server, which means it retrieves data without modifying state.
Register the Prompt Architect MCP server in PolicyLayer and add a rule for list_sessions: 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 Prompt Architect. Nothing to install.
list_sessions 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_sessions 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_sessions. 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_sessions is provided by the Prompt Architect MCP server (prompt-architect-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
