Part of the Foundry Zksync MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

// WHEN AI AGENTS USE THIS TOOL

AI agents use init to create or modify resources in Foundry Zksync. 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.

// WHY ENFORCE A POLICY ON INIT

Without a policy, an AI agent could call init repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Foundry Zksync.

// RECOMMENDED POLICY

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

// FAQ

What does the init tool do? +

Scaffold a new foundry project and add [profile.default.zksync] config (forge init). It is categorised as a Write tool in the Foundry Zksync MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on init? +

Add a rule in your Intercept YAML policy under the tools section for init. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Foundry Zksync MCP server.

What risk level is init? +

init is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit init? +

Yes. Add a rate_limit block to the init rule in your Intercept 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.

How do I block init completely? +

Set action: deny in the Intercept policy for init. 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.

What MCP server provides init? +

init is provided by the Foundry Zksync MCP server (foundry-zksync-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
