Create a new GitHub repository in your account
AI agents use create_repository to create or update resources in MCP-Brave-Search — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MCP-Brave-Search environment.
Creating a repository is a reversible Write operation: it modifies the user's account state by adding a new resource, but the action can be undone by deleting the repository. It does not execute arbitrary code, destroy existing data, or move money.
From the tool's definition Tool name is 'create_repository' and description states 'Create a new GitHub repository in your account' — this creates a new resource (repository) in the user's GitHub account.
Documented attack patterns abuse exactly the kind of access create_repository gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP-Brave-Search, and nothing reaches the server without passing your rules. This is the rule we recommend for create_repository:
{
"version": "1",
"default": "deny",
"tools": {
"create_repository": {
"limits": [
{
"counter": "create_repository_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_repository 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 GitHub repository in your account. It is categorised as a Write tool in the MCP-Brave-Search MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the MCP-Brave-Search MCP server in PolicyLayer and add a rule for create_repository: 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 MCP-Brave-Search. Nothing to install.
create_repository 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_repository 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_repository. 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_repository is provided by the MCP-Brave-Search MCP server (modelcontextprotocol/servers-archived). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from MCP-Brave-Search, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
