Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@stacks-mcp-serverCheck the STX balance for address SP3X6QWPEXAMPLE"
That's it! The server will respond to your query, and you can continue using it as needed.

TDQS
Scored across 8 tools
Each tool has a clearly distinct purpose: account generation, balance lookup, transaction info, network status, transaction search, block info, read-only contract calls, and API status. No two tools overlap in what they do, making selection unambiguous.
All tool names follow a consistent verb_noun pattern with lowercase and underscores (e.g., generate_account, get_balance, search_transactions). The verbs are varied but consistent in style, and the nouns clearly indicate the resource being acted upon.
With 8 tools, the server is within the ideal 3-15 range. Each tool covers a distinct aspect of Stacks blockchain interaction without being overwhelming or sparse, making the count well-scoped.
The tool set covers core query and read-only operations: accounts, balances, transactions, blocks, network status, and contract reads. However, there is no tool for submitting transactions or write operations, which could be a gap for a full blockchain interaction server, though it may be intended for read-only/query use.
