(Current plan: up to 1825 days of history.) ``` ### `fear_greed_index` - 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 Coins related to the given coin by category/sector similarity. ``` ### `stablecoin_earn_benchmark` - 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 The Bitcompare Earn Index for stablecoins: median USDC/USDT lending APY across servable providers, with CeFi/DeFi splits, TVL-weighted variant, deltas, and an immutable daily history. Use for "what does stablecoin yield pay right now / how has it trended?" — this is the citable market reference, not a single provider quote. ``` ### `stablecoin_index` - 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 Ranked stablecoin leaderboard with stability scores, peg deviation, and market cap. ``` ### `stablecoin_peg_stability` - 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.

Claude Code: allow. ### `get_coin` - The name "get_coin" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Full metadata for a coin: description, links, categories, market data, developer stats. ``` ### `get_price` - The name "get_price" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Current aggregated price for one or more symbols, computed from multiple exchange feeds. ``` ### `get_price_by_symbol` - The name "get_price_by_symbol" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Aggregated exchange price for one symbol, plus the raw per-provider prices that fed the aggregate. Use get_price for multiple symbols in one call. ``` ### `get_rate_by_symbol` - The name "get_rate_by_symbol" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Fetch all provider rates for a specific coin symbol. Optionally filter by category — pass category="lending"/"borrowing"/"staking" for yield questions, since unfiltered results mix in spot prices (category="price"). ``` ### `get_rate_changes` - The name "get_rate_changes" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text The immutable rate-change log: every material yield move with full provenance (previous rate, raw value, multiplier, collection method, confidence, base/bonus split). Time-ascending pages via cursor. Unfiltered windows are capped at 31 days — filter by provider or symbol to walk deep history. Use for "what changed since X?" and audit trails. ``` ### `get_rate_history` - The name "get_rate_history" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Historical rate timeseries for a symbol. Recent history (~30 days) is per-tick; older history is daily granularity. Depth is clamped to your plan (up to 365 days on Pro) and bounded by how far back data has been recorded. (Current plan: up to 1825 days of history.) ``` ### `get_rates` - The name "get_rates" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text List current rates across providers, optionally filtered by symbol, category, or provider. For "what is the best yield on BTC right now?" style questions, ALWAYS pass category="lending"/"borrowing"/"staking" — an unfiltered call mostly returns spot prices (category="price"), not yields. ``` ### `list_coins` - The name "list_coins" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text Paginated list of coins with optional name/symbol search. ``` ### `list_earn_products` - The name "list_earn_products" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text The canonical earn product graph: products (provider × asset × category) with their term variants — lockups, tiers, minimum deposits, payout schedules, withdrawal notice, TVL, promo flags — each carrying collection method, confidence (0-100 with bands), verification timestamps, and geo eligibility resolved from variant overrides or provider defaults. Use for "what are the actual terms behind this rate?" ``` ### `list_providers` - The name "list_providers" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text All rate providers, optionally filtered by product category. ``` ### `resolve_symbol` - The name "resolve_symbol" says "resolve": a word for reading. Description, as the server wrote it: ```untrusted-server-text Map an exchange-specific or ambiguous symbol to bitcompare's canonical coin id. Useful when an exchange uses a non-standard ticker. ``` ### `resolve_symbols_batch` - The name "resolve_symbols_batch" says "resolve": a word for reading. Description, as the server wrote it: ```untrusted-server-text Resolve up to 100 symbols in a single request. Requires a plan with bulk endpoints enabled. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `bitcompare`: ```json { "permissions": { "allow": [ "mcp__bitcompare__get_rates", "mcp__bitcompare__get_rate_by_symbol", "mcp__bitcompare__get_rate_history", "mcp__bitcompare__list_providers", "mcp__bitcompare__get_coin", "mcp__bitcompare__list_coins", "mcp__bitcompare__get_price", "mcp__bitcompare__get_price_by_symbol", "mcp__bitcompare__resolve_symbol", "mcp__bitcompare__resolve_symbols_batch", "mcp__bitcompare__get_rate_changes", "mcp__bitcompare__list_earn_products" ], "ask": [ "mcp__bitcompare__top_coins", "mcp__bitcompare__similar_coins", "mcp__bitcompare__coin_history", "mcp__bitcompare__market_summary", "mcp__bitcompare__fear_greed_index", "mcp__bitcompare__top_movers", "mcp__bitcompare__stablecoin_index", "mcp__bitcompare__stablecoin_peg_stability", "mcp__bitcompare__stablecoin_earn_benchmark" ], "deny": [] } } ```
