AI agents use create_wiki 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.
This tool creates a new wiki resource within an Azure DevOps project. Wiki creation is a reversible action (the wiki can be deleted or modified later), making it a Write operation rather than Destructive.
From the tool's definition Tool description: 'Create a new wiki in the project' — the verb 'create' indicates data is being added to the project in a reversible manner.
Documented attack patterns abuse exactly the kind of access create_wiki 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_wiki:
{
"version": "1",
"default": "deny",
"tools": {
"create_wiki": {
"limits": [
{
"counter": "create_wiki_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_wiki 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.
Free to start. No card required.
Create a new wiki in the project. 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_wiki: 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_wiki 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_wiki 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_wiki. 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_wiki 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.
