Claude Code: ask. ### `crypto_overview` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. Description, as the server wrote it: ```untrusted-server-text ONE SNAPSHOT OF CRYPTO ONLY, no arguments: the top 5 cryptos by Martingale Score (0-5) with their Startingale readings. Use this for a quick picture of crypto alone. To choose how many or apply a Startingale floor, use list_top_crypto; to cover stocks as well, use market_overview. Answers in formatted text. Costs 5 units of the monthly quota. ``` ### `market_overview` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. Description, as the server wrote it: ```untrusted-server-text ONE SNAPSHOT OF BOTH MARKETS, no arguments. Top instruments across crypto AND US stocks together, ranked by Martingale Score (0-5), with their Startingale readings. Use this to open a conversation or answer "how do things look right now". For a single asset class use crypto_overview or stock_overview; to choose the count or filter, use search_instruments. Answers in formatted text. Costs 10 units of the monthly quota: the most expensive call, since it reads both catalogues; the single-class overviews cost half, so do not call this in a loop. ``` ### `stock_overview` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. Description, as the server wrote it: ```untrusted-server-text ONE SNAPSHOT OF US STOCKS ONLY, no arguments: the top 5 stocks by Martingale Score (0-5) with their Startingale readings. Use this for a quick picture of stocks alone. To choose how many or apply a Startingale floor, use list_top_stocks; to cover crypto as well, use market_overview. Answers in formatted text. Costs 5 units of the monthly quota. ``` ## Only reads (4) Looks things up and changes nothing. Claude Code: allow. ### `get_instrument` - The name "get_instrument" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text ONE named instrument, in full. Returns the Martingale Score (0-5), the current Startingale reading, the score breakdown, the sequence structure (spacing, rounds, quantity multipliers) and exchange availability for a single crypto or US stock. Use this when you already know the symbol; use search_instruments to find symbols. Answers in formatted text, not JSON. Costs 1 unit of the monthly quota: the cheapest call, so walking a handful of known symbols one by one is fine. ``` ### `list_top_crypto` - The name "list_top_crypto" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text A RANKED LIST OF CRYPTOS, sized by you: choose how many (1-20) and an optional minimum Startingale. Use this when those two are the ONLY conditions; anything else (a venue, a round count, a minimum Martingale Score) needs search_instruments. For a fixed top 5 with no arguments, use crypto_overview. Answers in formatted text. Costs 3 units of the monthly quota. ``` ### `list_top_stocks` - The name "list_top_stocks" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text A RANKED LIST OF US STOCKS, sized by you: choose how many (1-20) and an optional minimum Startingale. Use this when those two are the ONLY conditions; anything else (a round count or a minimum Martingale Score) needs search_instruments. For a fixed top 5 with no arguments, use stock_overview. Answers in formatted text. Costs 3 units of the monthly quota. ``` ### `search_instruments` - The name "search_instruments" says "search": a word for reading. Description, as the server wrote it: ```untrusted-server-text THE QUERY TOOL: find instruments matching criteria across an asset class. Filter by minimum Martingale score, minimum Startingale, exchange and more; returns a ranked list. Use it when a filter OTHER than count or Startingale floor is needed: exchange, round count, or a minimum Martingale Score. If the only conditions are how many and a Startingale floor, list_top_crypto or list_top_stocks do the same in one step; for no conditions at all, use an overview. Answers in formatted text. Costs 3 units of the monthly quota. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `tradingale`: ```json { "permissions": { "allow": [ "mcp__tradingale__get_instrument", "mcp__tradingale__search_instruments", "mcp__tradingale__list_top_crypto", "mcp__tradingale__list_top_stocks" ], "ask": [ "mcp__tradingale__market_overview", "mcp__tradingale__crypto_overview", "mcp__tradingale__stock_overview" ], "deny": [] } } ``` ## Remote posture What an anonymous client saw at the remote endpoint, last 2026-10-22T15:06:53.039Z, unchanged since 2026-10-22T15:06:53.039Z. No credentials were sent and no tool was called. Values are shown as the endpoint returned them.
