Scan the recent snapshot history for chronic problems:
AI agents call get_drift_signature to retrieve information from Mk Spec Master without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and analyzes snapshots from history to identify problems—a read-only operation with no side effects. It does not modify, execute commands, delete data, or create financial obligations. The blast radius of misuse is minimal; an AI agent cannot cause harm by scanning history for drift metrics.
From the tool's definition Tool name 'get_drift_signature' and description 'Scan the recent snapshot history for chronic problems' indicate querying/analyzing historical data. The verb 'scan' and noun 'signature' suggest read-only inspection of records to identify patterns.
Attacks that exploit this kind of access
Scan the recent snapshot history for chronic problems:. It is categorised as a Read tool in the Mk Spec Master MCP Server, which means it retrieves data without modifying state.
Register the Mk Spec Master MCP server in PolicyLayer and add a rule for get_drift_signature: 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 Spec Master. Nothing to install.
get_drift_signature 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_drift_signature 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_drift_signature. 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_drift_signature is provided by the Mk Spec Master MCP server (kao273183/mk-spec-master). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
