# Chainstack updates: July 23, 2026

> The Chainstack MCP server's testnet faucet now advertises its supported networks to your agent and accepts common network-name aliases, so testnet fund requests land on the first try.

**MCP Server**. The [Chainstack MCP server](https://mcp.chainstack.com) testnet faucet (`request_testnet_funds`) now tells your agent exactly which testnets it supports — the supported networks are published as a schema enum, so the agent picks a valid one up front instead of guessing. Common near-miss spellings are also accepted and normalized to the canonical id — `ethereum-sepolia` → `sepolia`, `base-sepolia` → `base`, `solana-devnet` → `solana` — so a slightly-off network name still delivers the funds. Supported testnets: sepolia, hoodi, base, amoy, bnb-testnet, zksync-testnet, scroll-sepolia-testnet, hyperevm, plasma, monad, ton, and solana (Solana devnet).
