AI agents call list_dev_assignments to retrieve information from Tickr without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only query operation that retrieves assignment data from the system. It has no capability to modify, create, delete, or execute actions—only to fetch and display information about existing dev assignments. Severity is low because exposure of assignment metadata presents minimal risk of harm even if misused by an AI agent.
From the tool's definition Tool name 'list_dev_assignments' and description 'List all dev queue assignments' indicate retrieval of existing data with no modification or deletion.
Attacks that exploit this kind of access
List all dev queue assignments (pending, in-progress, completed, failed). It is categorised as a Read tool in the Tickr MCP Server, which means it retrieves data without modifying state.
Register the Tickr MCP server in PolicyLayer and add a rule for list_dev_assignments: 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 Tickr. Nothing to install.
list_dev_assignments 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_dev_assignments 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_dev_assignments. 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_dev_assignments is provided by the Tickr MCP server (@k-system/tickr-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
