Show commit log
AI agents call vcs_log to retrieve information from Node Dev MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves version control history for informational purposes only. Displaying commit logs has no side effects, does not execute code, does not modify files or repositories, and does not delete or overwrite data. It is a read-only operation that merely queries and displays existing Git metadata.
From the tool's definition Tool name 'vcs_log' and description 'Show commit log' indicate a query operation that retrieves and displays Git commit history without modifying any data.
Attacks that exploit this kind of access
Show commit log. It is categorised as a Read tool in the Node Dev MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Node Dev MCP Server MCP server in PolicyLayer and add a rule for vcs_log: 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 Node Dev MCP Server. Nothing to install.
vcs_log 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 vcs_log 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 vcs_log. 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.
vcs_log is provided by the Node Dev MCP Server MCP server (liamcarver/node-dev-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
