Create a new pull request, including reviewers, linked work items, and optional tags
AI agents use create_pull_request to create or update resources in Azure DevOps MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Azure DevOps MCP Server environment.
Creating a pull request is a reversible write operation that adds new metadata/records to the system but does not execute code, destroy data, or move money. The blast radius is medium: an AI agent could create numerous spurious PRs, trigger notifications, or pollute the repository history, but the action itself is not destructive or irreversible.
From the tool's definition Tool description states 'Create a new pull request' — a write operation that creates a new resource in Azure DevOps. It modifies repository state by introducing a new PR record, which is reversible (PRs can be closed/abandoned without permanent data loss).
Documented attack patterns abuse exactly the kind of access create_pull_request 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 create_pull_request:
{
"version": "1",
"default": "deny",
"tools": {
"create_pull_request": {
"limits": [
{
"counter": "create_pull_request_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_pull_request stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Create a new pull request, including reviewers, linked work items, and optional tags. It is categorised as a Write tool in the Azure DevOps MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Azure DevOps MCP Server MCP server in PolicyLayer and add a rule for create_pull_request: 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.
create_pull_request is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the create_pull_request 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 create_pull_request. 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.
create_pull_request 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.
