Connect MCP Server and your agent gets 16 tools, among them __unlock_blockchain_analysis__, direct_api_call, get_address_by_ens_name. It answers at https://mcp.blockscout.com/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 10 of 10 times since 4 September 2026; the last check, on 18 October 2026, succeeded.
MCP server for Blockscout
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
__unlock_blockchain_analysis__ | 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 |
direct_api_call | 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-in Inputs: chain_id, endpoint_path, query_params, cursor, method, json_body |
get_address_by_ens_name | Useful for when you need to convert an ENS domain name (e.g. "blockscout.eth") to its corresponding Ethereum address. Inputs: name, session_id |
get_address_info | Get comprehensive information about an address, including: - Address existence check - Native token (ETH) balance (provided as is, without adjusting by decimals) - First transaction details (block number and timestamp) for age calculation - Inputs: chain_id, address, session_id |
get_block_info | 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 nee Inputs: chain_id, number_or_hash, include_transactions, session_id |
get_block_number | 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 th Inputs: chain_id, datetime, session_id |
get_chains_list | 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 curren Inputs: query, session_id |
get_contract_abi | Get smart contract ABI (Application Binary Interface). An ABI defines all functions, events, their parameters, and return types. The ABI is required to format function calls or interpret contract data. Inputs: chain_id, address, session_id |
get_token_transfers_by_address | Get ERC-20 token transfers for an address within a specific time range. **SUPPORTS PAGINATION**: If response includes 'pagination' field, use the provided next_call to get additional pages. Inputs: chain_id, address, age_from, age_to, token, cursor |
get_tokens_by_address | Get comprehensive ERC20 token holdings for an address with enriched metadata and market data. Returns detailed token information including contract details (name, symbol, decimals), market metrics (exchange rate, market cap, volume), holder Inputs: chain_id, address, cursor, session_id |
get_transaction_info | 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, Inputs: chain_id, transaction_hash, include_raw_input, session_id |
get_transactions_by_address | 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 Inputs: chain_id, address, age_from, age_to, methods, cursor |
inspect_contract_code | Inspects a verified contract's source code or metadata. Inputs: chain_id, address, file_name, session_id |
lookup_token_by_symbol | Search for token addresses by symbol or name. Returns multiple potential matches based on symbol or token name similarity. Only the first 7 matches from the Blockscout API are returned. Inputs: chain_id, symbol, session_id |
nft_tokens_by_address | Retrieve NFT tokens (ERC-721, ERC-404, ERC-1155) owned by an address, grouped by collection. Provides collection details (type, address, name, symbol, total supply, holder count) and individual token instance data (ID, name, description, ex Inputs: chain_id, address, cursor, session_id |
read_contract | Calls a smart contract function (view/pure, or non-view/pure simulated via eth_call) and returns the decoded result. This tool provides a direct way to query the state of a smart contract. Example: To check the USDT balance of an address on Inputs: chain_id, address, abi, function_name, args, block |

Yes. It is published by blockscout.com and served from mcp.blockscout.com, the vendor's own domain: https://mcp.blockscout.com/mcp.
16, as returned by the server's own tools/list on 10 September 2026: __unlock_blockchain_analysis__, direct_api_call, get_address_by_ens_name, get_address_info, get_block_info, get_block_number, get_chains_list, get_contract_abi, and 8 more.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://mcp.blockscout.com/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
Publisher: com.blockscout. Endpoint host: mcp.blockscout.com. ARD identifier: urn:air:com.blockscout:mcp:mcp-server.
First indexed 31 August 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
