Snapshot of every spec ↔ test link recorded in the local
AI agents call get_coverage_matrix 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 queries stored metadata (spec-to-test traceability links) and returns a read-only view. It has no side effects, does not trigger external operations, and does not modify or delete data. The blast radius of misuse is minimal — an agent could retrieve coverage information it shouldn't see, but cannot cause harm to specs, tests, or external systems.
From the tool's definition 'Snapshot of every spec ↔ test link recorded in the local' — the tool retrieves and reports on existing links without modifying, deleting, or executing external operations. The verb 'snapshot' and 'recorded' indicate passive retrieval.

Attacks that exploit this kind of access
Snapshot of every spec ↔ test link recorded in the local. 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_coverage_matrix: 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_coverage_matrix 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_coverage_matrix 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_coverage_matrix. 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_coverage_matrix 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.
