# Chainstack updates: October 12, 2026

> The Chainstack MCP server now returns every project in organizations with more than 100, names the city for each deployment region, and tells your AI agent when a testnet faucet top-up is done.

**MCP Server**. The [Chainstack MCP server](https://mcp.chainstack.com) has these updates:

* `list_projects` returns every project in organizations with more than 100 projects. Previously, the second page of results repeated the first.
* Deployment options include `region_name`, the city for each region code, so your AI agent can match a location such as London without guessing codes.
* When the [Chainstack faucet](/docs/faucets) tops up an address through the MCP server, the response tells the agent that the funds were sent and not to request the same network again.
* The faucet tool states the cooldown: one top-up per network every 24 hours, refused if your organization or the destination address already got funds on that network.
