Description, as the server wrote it: ```untrusted-server-text Your account's webhooks: URL, state (pending_verification, active, disabled with the reason and how to enable), failures in a row, subscriptions. A rotated key sees the same webhooks. Next page: pass `next_cursor` as cursor. ``` ### `search_coins` - The name "search_coins" says "search": a word for reading. Description, as the server wrote it: ```untrusted-server-text Tokens by symbol, name or address, with their links across layers (Elysium <-> HyperEVM <-> HyperCore), decimals, supply and USD price. Without layer: every layer. An exact address always answers its token (spam flagged). ``` ### `search_entities` - The name "search_entities" says "search": a word for reading. Description, as the server wrote it: ```untrusted-server-text Named wallets (KOLs, traders, funds, market makers) and their wallets, from public attribution lists (not verified identities). A named wallet's address is given as its handle ., usable as an address in every tool. Use the entity id with kol_activity. Next page: pass `next_cursor` as cursor. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `femtos`: ```json { "permissions": { "allow": [ "mcp__femtos__get_status", "mcp__femtos__list_markets", "mcp__femtos__get_candles", "mcp__femtos__get_trades", "mcp__femtos__search_coins", "mcp__femtos__get_coin", "mcp__femtos__get_holders", "mcp__femtos__list_launches", "mcp__femtos__list_new_tokens", "mcp__femtos__list_new_pools", "mcp__femtos__get_launch", "mcp__femtos__get_launch_timeline", "mcp__femtos__get_token_lifecycle", "mcp__femtos__get_token_security", "mcp__femtos__get_prices", "mcp__femtos__get_price_history", "mcp__femtos__get_tokens", "mcp__femtos__get_token_overview", "mcp__femtos__get_bridges", "mcp__femtos__get_wallet", "mcp__femtos__get_balances", "mcp__femtos__get_token_balance", "mcp__femtos__get_token_volume", "mcp__femtos__get_erc20_transfers", "mcp__femtos__get_pool", "mcp__femtos__get_transaction", "mcp__femtos__get_book", "mcp__femtos__get_liquidations", "mcp__femtos__get_liquidation_stats", "mcp__femtos__get_liquidation_map", "mcp__femtos__get_wallet_stops", "mcp__femtos__list_nft_collections", "mcp__femtos__get_nft_collection", "mcp__femtos__get_nft_tokens", "mcp__femtos__get_nfts_owned", "mcp__femtos__search_entities", "mcp__femtos__list_webhooks", "mcp__femtos__get_webhook_deliveries" ], "ask": [ "mcp__femtos__get_positions", "mcp__femtos__get_stop_map", "mcp__femtos__get_forced_flow", "mcp__femtos__get_triggered_stops", "mcp__femtos__get_nft_transfers", "mcp__femtos__kol_leaderboard", "mcp__femtos__kol_activity", "mcp__femtos__create_webhook", "mcp__femtos__test_webhook", "mcp__femtos__replay_webhook" ], "deny": [ "mcp__femtos__delete_webhook" ] } } ``` Capability tags behind the rules (a read tagged outbound is asked about): - `mcp__femtos__get_nft_tokens`: untrusted-input - `mcp__femtos__create_webhook`: untrusted-input, outbound - `mcp__femtos__list_webhooks`: untrusted-input - `mcp__femtos__test_webhook`: untrusted-input - `mcp__femtos__get_webhook_deliveries`: untrusted-input - `mcp__femtos__replay_webhook`: untrusted-input, outbound ## Remote posture What an anonymous client saw at the remote endpoint, last 2026-10-22T15:16:22.041Z, unchanged since 2026-10-22T15:16:22.041Z.
