Return the active initiative source (selected via PLAN_SOURCE env var)
AI agents call get_plan_source_info to retrieve information from Mk Plan Master without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a simple read/lookup of configuration state (PLAN_SOURCE environment variable). It retrieves information without creating, modifying, deleting, or executing any external operations. The blast radius of misuse is minimal—an attacker learns which initiative source is configured, which provides no direct leverage to compromise systems or data. This is a low-risk information retrieval operation.
From the tool's definition Tool returns the active initiative source via environment variable lookup—a pure query operation with no modification or side effects. Name 'get_plan_source_info' and description 'Return the active initiative source' indicate retrieval only.
Attacks that exploit this kind of access
Return the active initiative source (selected via PLAN_SOURCE env var). It is categorised as a Read tool in the Mk Plan Master MCP Server, which means it retrieves data without modifying state.
Register the Mk Plan Master MCP server in PolicyLayer and add a rule for get_plan_source_info: 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 Mk Plan Master. Nothing to install.
get_plan_source_info 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 get_plan_source_info 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 get_plan_source_info. 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.
get_plan_source_info is provided by the Mk Plan Master MCP server (kao273183/mk-plan-master). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
