AI agents call disassemble_teal to retrieve information from Algorand MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Disassembly is a read-only operation that converts compiled bytecode into human-readable source code for analysis or inspection purposes. It has no side effects, does not execute code, does not modify data, and does not affect blockchain state or financial transactions. This is purely informational/retrieval functionality.
From the tool's definition Tool name 'disassemble_teal' and description 'Disassemble TEAL bytecode back to source' indicate a one-way conversion operation that retrieves and presents information about existing bytecode without modifying, executing, or deleting anything.
Documented attack patterns abuse exactly the kind of access disassemble_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 disassemble_teal:
{
"version": "1",
"default": "deny",
"tools": {
"disassemble_teal": {}
}
}disassemble_teal is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Disassemble TEAL bytecode back to source. It is categorised as a Read tool in the Algorand MCP MCP Server, which means it retrieves data without modifying state.
Register the Algorand MCP server in PolicyLayer and add a rule for disassemble_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.
disassemble_teal is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the disassemble_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 disassemble_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.
disassemble_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.
