Create a new PromptHub repository from a full set of fields. Use this when the user explicitly provides repo content to publish. (To publish the CURRENT coding session, prefer prompthub_publish_session.) Call prompthub_describe_file_format if unsure of the files[] shape.
AI agents use prompthub_create_repo to create or update resources in Prompthub — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Prompthub environment.
This tool creates new repository content, which is a reversible write operation. It does not delete data (Destructive), execute arbitrary code (Execute), involve financial transactions (Financial), or move data irreversibly.
From the tool's definition Tool name contains 'create' and description states 'Create a new PromptHub repository' - this is a create operation that adds new data to a repository system.

Create a new PromptHub repository from a full set of fields. Use this when the user explicitly provides repo content to publish. (To publish the CURRENT coding session, prefer prompthub_publish_session.) Call prompthub_describe_file_format if unsure of the files[] shape. It is categorised as a Write tool in the Prompthub MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Prompthub MCP server in PolicyLayer and add a rule for prompthub_create_repo: 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 Prompthub. Nothing to install.
prompthub_create_repo 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 prompthub_create_repo 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 prompthub_create_repo. 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.
prompthub_create_repo is provided by the Prompthub MCP server (lionelhao/prompthub-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
