# Generate MCP allowlist fragment for a public chain from deployment-status.json.
# Reads cross-chain-pmm-lps/config/deployment-status.json and outputs pools for the given chainId.
#
# Usage:
#   ./scripts/generate-mcp-allowlist-from-deployment-status.sh <chain_id>   # e.g. 137
#   ./scripts/generate-mcp-allowlist-from-deployment-status.sh 137 -o fragment-137.json
#
# Output: JSON with "chain", "pools" (array of {name, pool_address, base_token, quote_token, profile}).
# pmmPools in deployment-status must have poolAddress (or pool_address), base, quote (or base_token, quote_token).
