Why estimate_bridge_time needs a policy

This tool performs a read-only estimation query about bridge transfer timing. It retrieves or computes information without side effects, making state changes, or committing financial transactions. While it operates in a crypto/DeFi context, the tool itself only provides informational estimates and does not interact with wallets, execute swaps, move funds, or trigger irreversible actions.

From the tool's definition Tool name 'estimate_bridge_time' and description 'Estimate how long a bridge transfer will take' indicate a query/lookup operation that retrieves estimated timing data without modifying state or executing transactions.

POLICY

How to control estimate_bridge_time

PolicyLayer is an MCP gateway — it sits between your AI agents and Sperax Ecosystem Crypto & DeFI MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for estimate_bridge_time:

policy.json

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

estimate_bridge_time is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
