List all sessions in the current workspace.
AI agents call coord_list_sessions to retrieve information from Session Coord 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 information about existing sessions without modifying, deleting, or executing any operations. The verb 'List' is a classic read operation. The local-first, coordination-focused nature of the server and the presence of other tools like 'coord_claim_paths' and 'coord_complete_task' confirm this is a data retrieval utility.
From the tool's definition Tool name 'coord_list_sessions' and description 'List all sessions in the current workspace' indicate a query/retrieval operation with no side effects.
Attacks that exploit this kind of access
List all sessions in the current workspace. It is categorised as a Read tool in the Session Coord MCP Server, which means it retrieves data without modifying state.
Register the Session Coord MCP server in PolicyLayer and add a rule for coord_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 Session Coord. Nothing to install.
coord_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 coord_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 coord_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.
coord_list_sessions is provided by the Session Coord MCP server (lingfeng-vels/session-coord-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
