Fetch recent updates with optional filters.
AI agents call coord_get_updates 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 queries and retrieves update information from the session coordination system without modifying, deleting, or executing operations. It is a passive data retrieval mechanism suitable for monitoring status in a parallel coding workflow. No side effects or state changes occur.
From the tool's definition Tool description explicitly states 'Fetch recent updates' with optional filters. 'Fetch' is a retrieval operation with no side effects.
Attacks that exploit this kind of access
Fetch recent updates with optional filters. 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_get_updates: 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_get_updates 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_get_updates 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_get_updates. 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_get_updates 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.
