WHAT IT DOES

What decode_obj does on Algorand MCP

AI agents call decode_obj to retrieve information from Algorand MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why decode_obj is rated Low

Decoding is a read operation that transforms data from one format to another without modifying state, creating resources, executing external operations, or causing irreversible changes. The tool merely interprets existing data.

From the tool's definition Tool name 'decode_obj' and description 'Decode msgpack bytes to an object' indicate a data decoding operation that retrieves/parses information with no side effects.

RECOMMENDED RULE

The rule that runs decode_obj safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Algorand MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For decode_obj, this is the rule to start with:

decode_obj Allowed

decode_obj is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "decode_obj": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Algorand MCP, apply this rule, and every decode_obj call is checked against it from then on.
