WHAT IT DOES

What defillama_protocol does on Codex CCXT MCP

AI agents call defillama_protocol to retrieve information from Codex CCXT 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 defillama_protocol is rated Low

This tool retrieves public data from DefiLlama's free endpoint. It performs a read-only query operation with no ability to modify, delete, or execute code. The data is public and the operation has no financial impact or side effects. Severity is low because misuse would only result in unnecessary API calls or data retrieval.

From the tool's definition Tool description states 'Fetch DefiLlama public historical TVL and protocol metadata by slug. Read-only, free public endpoint.' The explicit mention of 'Read-only' and 'Fetch' confirms retrieval without side effects.

RECOMMENDED RULE

The rule that runs defillama_protocol safely

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

defillama_protocol Allowed

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

  "default": "deny",
  "tools": {
    "defillama_protocol": {}
  }
}

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

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