AI agents call prepare_task_context to retrieve information from RoadBoard without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves and assembles existing information (project info, task details, sibling tasks, memory entries) without creating, modifying, or deleting any data. It is a pure read/query operation.
From the tool's definition Assemble full context for a task: project info, the task itself, sibling tasks in the same phase, and recent memory entries
Attacks that exploit this kind of access
Assemble full context for a task: project info, the task itself, sibling tasks in the same phase, and recent memory entries. It is categorised as a Read tool in the RoadBoard MCP Server, which means it retrieves data without modifying state.
Register the RoadBoard MCP server in PolicyLayer and add a rule for prepare_task_context: 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 RoadBoard. Nothing to install.
prepare_task_context 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 prepare_task_context 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 prepare_task_context. 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.
prepare_task_context is provided by the RoadBoard MCP server (maless88/roadboard). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
