THE RISK

High Risk

Compiling TEAL code is an Execute action because it triggers code transformation and compilation processes whose effects (generation of executable smart contract bytecode) depend on the source code arguments provided. While compilation itself is not destructive, the resulting bytecode can be deployed to perform arbitrary on-chain operations.

From the tool's definition Tool name is 'compile_teal' with description 'Compile TEAL source code'. TEAL is a smart contract language used in the Algorand ecosystem. Compilation transforms source code into executable bytecode that can be deployed and executed on-chain.

HOW TO CONTROL COMPILE_TEAL

PolicyLayer is an MCP gateway — it sits between your AI agents and BNB Chain MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for compile_teal:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "compile_teal": {
      "limits": [
        {
          "counter": "compile_teal_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

compile_teal stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register BNB Chain MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

What does the compile_teal tool do? +

Compile TEAL source code. It is categorised as a Execute tool in the BNB Chain MCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on compile_teal? +

Register the BNB Chain MCP server in PolicyLayer and add a rule for compile_teal: 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 BNB Chain MCP. Nothing to install.

What risk level is compile_teal? +

compile_teal is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit compile_teal? +

Yes. Add a rate_limit block to the compile_teal 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.

How do I block compile_teal completely? +

Set action: deny in the PolicyLayer policy for compile_teal. 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 compile_teal? +

compile_teal is provided by the BNB Chain MCP server (nirholas/bnbchain-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every BNB Chain MCP tool call.
