AI agents use addRemoteMcpServer to create or modify resources in DataGen. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call addRemoteMcpServer repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach DataGen.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Other write tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Add a remote MCP server with OAuth or direct URL to DataGen. <Find Remote MCP Server URL> Before adding a remote MCP server, and if you have web research tool, you should first search and find the officail remote MCP server with their URL. If No official remote MCP available, recommend user to look for MCP hosted services like smithery.ai(https://smithery.ai), Klavis AI(https://klavis.ai), etc. to add the remote MCP server. </Find Remote MCP Server URL> <Add Remote MCP Server> Directly add remote MCP servers by providing server name, and URL </Add Remote MCP Server> Supports OAuth flows. Returns available tools upon successful connection. Perfect for: - Connecting to external MCP services to DataGen Input Requirements: - server_name: Display name for the server (must follow naming rules) - server_url: Remote server endpoint (HTTP/SSE) Naming Rules: - Use only alphanumeric characters (no spaces, underscores, or dashes) - Start with an uppercase letter - Use CamelCase for multiple words - Examples: 'GitHub', 'Slack', 'GoogleDrive' Returns: - Server info + complete list of available tools with descriptions or auth url if OAuth is required. - if success is false, it means the server is not found or the URL is not valid. - if Auth url is returned, plese use the proper formating like [Auth url](https://your-auth-url.com) to format the auth url. and use checkRemoteMcpOauthStatus tool to check the status of the OAuth flow right after this tool call.. It is categorised as a Write tool in the DataGen MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the DataGen MCP server in PolicyLayer and add a rule for addRemoteMcpServer: 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 DataGen. Nothing to install.
addRemoteMcpServer 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 addRemoteMcpServer 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 addRemoteMcpServer. 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.
addRemoteMcpServer is provided by the DataGen MCP server (kuoyusheng/datagendev). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
