AI agents call validate_commit_message 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 tool performs validation—comparing a commit message string against a set of rules and returning pass/fail results. It reads configuration and the commit message itself but does not execute code, create/modify data, delete anything, or trigger external operations. The severity is low because validation failures have no side effects; they simply provide feedback.
From the tool's definition Tool name 'validate_commit_message' and description indicate validation/checking of commit messages against configured rules.

Validate a commit message against configured rules. Checks: - Title length (max characters) - Conventional commit format (if configured) - Required scope (if configured) - Imperative mood (e.g.,. It is categorised as a Read tool in the Pr Narrator MCP Server, which means it retrieves data without modifying state.
Register the Pr Narrator MCP server in PolicyLayer and add a rule for validate_commit_message: 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.
validate_commit_message 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 validate_commit_message 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 validate_commit_message. 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.
validate_commit_message 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.
