AI agents use add_helper_scripts to create or modify resources in Mcp Klever Vm. 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 add_helper_scripts 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 Mcp Klever Vm.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Add build, deploy, upgrade, query, test, and interact automation scripts to an existing Klever smart contract project. Creates a scripts/ directory with bash scripts and updates .gitignore. Run this from the project root directory (where Cargo.toml is located). NOTE: In public profile, this tool returns a project template JSON and does not perform any filesystem changes.. It is categorised as a Write tool in the Mcp Klever Vm MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Mcp Klever Vm MCP server in PolicyLayer and add a rule for add_helper_scripts: 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 Klever Vm. Nothing to install.
add_helper_scripts 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 add_helper_scripts 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 add_helper_scripts. 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.
add_helper_scripts is provided by the Mcp Klever Vm MCP server (@klever/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
