AI agents invoke compile_teal to trigger actions in Algorand MCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
This tool executes a compiler to transform TEAL source code into bytecode. While compilation itself is deterministic, the resulting bytecode can be deployed to perform arbitrary blockchain operations (transfers, state changes, etc.). In the context of an AI agent with access to sibling tools like alpha_create_market_order and alpha_claim, compiled contracts could be weaponized.
From the tool's definition Compile TEAL source code - TEAL is Algorand's smart contract language; compilation is code execution that produces executable bytecode for blockchain deployment
Documented attack patterns abuse exactly the kind of access compile_teal gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Algorand MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for compile_teal:
{
"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.
Free to start. No card required.
Compile TEAL source code. It is categorised as a Execute tool in the Algorand MCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Algorand 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 Algorand MCP. Nothing to install.
compile_teal is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
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.
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.
compile_teal is provided by the Algorand MCP server (goplausible/algorand-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Algorand MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
