List recent commits on a branch including file-level diff content for each commit
AI agents call list_commits to retrieve information from Azure DevOps MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves commit history and diff information without altering any state or triggering external operations. It is a pure read operation with minimal blast radius—an AI agent misusing it could only over-retrieve data, not cause damage to infrastructure or data integrity.
From the tool's definition Tool name 'list_commits' and description 'List recent commits on a branch including file-level diff content for each commit' indicate retrieval of historical commit data and associated diffs.
Documented attack patterns abuse exactly the kind of access list_commits gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Azure DevOps MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_commits:
{
"version": "1",
"default": "deny",
"tools": {
"list_commits": {}
}
}list_commits is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
List recent commits on a branch including file-level diff content for each commit. It is categorised as a Read tool in the Azure DevOps MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Azure DevOps MCP Server MCP server in PolicyLayer and add a rule for list_commits: 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 Azure DevOps MCP Server. Nothing to install.
list_commits 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 list_commits 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 list_commits. 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.
list_commits is provided by the Azure DevOps MCP Server MCP server (tiberriver256/mcp-server-azure-devops). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
