Est-ce que com.blockscout/mcp-server est sûr ?

Au dernier audit MCP Hub, le serveur MCP « com.blockscout/mcp-server » est classé « Non encore testé ». Référencé dans l'annuaire. Seul le pentest comportemental fait foi, et il n'a pas encore été exécuté sur ce serveur. Le verdict est réévalué en continu ; consultez la fiche pour l'état à jour.

Méthode : MCP Hub analyse la description de chaque outil (couche 1) et, pour le verdict fort, exécute le serveur dans une micro-VM isolée avec leurres et réseau bloqué (couche 2). On publie des noms et des compteurs, jamais le contenu brut renvoyé par un outil.

Les 16 outils

• __unlock_blockchain_analysis__≈ 890 tokens

  Initializes a Blockscout MCP session: returns server reference data, the `blockscout-analysis` skill pointer, and the URI resolution rule. Call this tool exactly once per session, before any other tool, and reuse its payload for the rest of the session; do not call it again.

• direct_api_call≈ 1134 tokens

  Call a raw Blockscout API endpoint for advanced or chain-specific data. Before the first call to this tool in a session, read `blockscout-mcp://skill/SKILL.md` (the operating rules), then `blockscout-mcp://skill/references/blockscout-api-index.md` (the authoritative index of callable endpoints); skip both reads only if this skill content is already in context. Recalled Blockscout API knowledge is not a substitute: endpoint paths, parameters, and response shapes vary across Blockscout versions and per-chain deployments. Supports POST requests with a JSON body for endpoints like JSON RPC. **SUPPORTS PAGINATION**: If response includes 'pagination' field, use the provided next_call to get additional pages (GET only).

  Get block information like timestamp, gas used, burnt fees, transaction count etc. Can optionally include the list of transaction hashes contained in the block. Transaction hashes are omitted by default; request them only when you truly need them, because on high-traffic chains the list may exhaust the context.

• get_block_number≈ 950 tokens

  Retrieves the block number and timestamp for a specific date/time or the latest block. Use when you need a block height for a specific point in time (e.g., "block at 2024-01-01") or the current chain tip. If `datetime` is provided, finds the block immediately preceding that time.

• get_chains_list≈ 1157 tokens

  Get supported blockchain chains with their chain IDs. Ethereum Mainnet is `chain_id` `1`; use this tool to resolve any other chain. Use this when another tool needs a supported `chain_id` and only the chain name, ecosystem, or native currency is known. Prefer a narrow `query` to avoid returning the full registry to the agent. Do not rely on partial numeric chain ID queries such as `1`, because matching is substring-based and may return many chains.

• get_transaction_info≈ 1726 tokens

  Get comprehensive transaction information. Unlike standard eth_getTransactionByHash, this tool returns enriched data including decoded input parameters, detailed token transfers with token metadata, transaction fee breakdown (priority fees, burnt fees) and categorized transaction types. By default, the raw transaction input is omitted if a decoded version is available to save context; request it with `include_raw_input=True` only when you truly need the raw hex data. Essential for transaction analysis, debugging smart contract interactions, tracking DeFi operations.

  Retrieves native currency transfers and smart contract interactions (calls, internal txs) for an address. **EXCLUDES TOKEN TRANSFERS**: Filters out direct token balance changes (ERC-20, etc.). You'll see calls *to* token contracts, but not the `Transfer` events. For token history, use `get_token_transfers_by_address`. A single tx can have multiple records from internal calls.
