Why get_treaty is rated Low
This tool appears to retrieve treaty information from UK Parliament records. Based on the server's stated purpose of giving 'access to UK Parliament data' through queries and the pattern of sibling tools (all read operations like get_amendment_by_id, get_act_of_parliament, get_all_bills_rss), this is clearly a Read operation that queries and returns data without modification or side effects.
From the tool's definition Tool name 'get_treaty' and context of UK Parliament MCP server (which provides access to query MPs, Lords, bills, votes, committees, debates, and more). The sibling tools are all read-only queries (bill_stages, bill_types, browse_*, check_mp_vote, get_*).
