AI agents call list_activity to retrieve information from Codecks 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 activity information from the project management system without creating, modifying, deleting, or executing any changes. It has no side effects and presents no risk of data loss, unwanted execution, or financial impact. The blast radius of misuse is minimal—an agent could only view activity data it may not be authorized to see, but cannot alter or destroy anything.
From the tool's definition Tool name 'list_activity' combined with description 'Show recent activity feed' indicates data retrieval with no modification. The verb 'list' and 'show' are characteristic of read-only operations that query and return existing data.
Attacks that exploit this kind of access
Show recent activity feed. It is categorised as a Read tool in the Codecks MCP Server, which means it retrieves data without modifying state.
Register the Codecks MCP server in PolicyLayer and add a rule for list_activity: 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 Codecks. Nothing to install.
list_activity 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_activity 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_activity. 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_activity is provided by the Codecks MCP server (rangogamedev/codecks-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
