AI agents call get_config to retrieve information from Pr Narrator without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a straightforward Read operation—it retrieves configuration settings without creating, modifying, deleting, or executing any operations. The blast radius is minimal since it only exposes read-only configuration details. Severity is low because configuration exposure is typically informational and not immediately exploitable without other actions.
From the tool's definition Tool name 'get_config' and description 'Get the current pr-narrator configuration. Returns settings from MCP env vars or defaults.' indicate a retrieval operation with no side effects.

Register the Pr Narrator MCP server in PolicyLayer and add a rule for get_config: 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 Pr Narrator. Nothing to install.
get_config 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_config 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_config. 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_config is provided by the Pr Narrator MCP server (mhaviv/pr-narrator-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
