blockscout-mcp-server
Registry code: 4b9a3ad6761a84b2
Blockscout MCP server version: 0.19.0
Operating rules, execution strategies, and the curated `direct_api_call` endpoint reference for analyzing Blockscout data live in the `blockscout-analysis` skill (version 0.6.0). If the skill is already loaded in your context, use that copy. If no copy is loaded, fetch the entry point from `blockscout-mcp://skill/SKILL.md` over MCP resources or `GET /skill/SKILL.md` over HTTP.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.
__unlock_blockchain_analysis__ reads open 13h ago
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.
{ "type": "object", "title": "__unlock_blockchain_analysis__Arguments", "properties": {} }arguments 5 linesget_block_number reads unknown 10h ago
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. If omitted, returns the latest indexed block.

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. Requires an `age_from` date to scope results for performance and relevance. **SUPPORTS PAGINATION**: If response includes 'pagination' field, use the provided next_call to get additional pages.

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), holders count, and actual balance (provided as is, without adjusting by decimals). Essential for portfolio analysis, wallet auditing, and DeFi position tracking. **SUPPORTS PAGINATION**: If response includes 'pagination' field, use the provided next_call to get additional pages.

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, external URL, metadata attributes). Essential for a detailed overview of an address's digital collectibles and their associated collection data. **SUPPORTS PAGINATION**: If response includes 'pagination' field, use the provided next_call to get additional pages.

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.

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 Ethereum Mainnet, you would use the following arguments: { "tool_name": "read_contract", "params": { "chain_id": "1", "address": "0xdAC17F958D2ee523a2206206994597C13D831ec7", "abi": { "constant": true, "inputs": [{"name": "_owner", "type": "address"}], "name": "balanceOf", "outputs": [{"name": "balance", "type": "uint256"}], "payable": false, "stateMutability": "view", "type": "function" }, "function_name": "balanceOf", "args": "["0xF977814e90dA44bFA03b6295A0616a897441aceC"]" } }

This must match the `name` field in the provided ABI." } } }arguments 65 linesget_transaction_info reads unknown 10h ago
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.
{ "type": "object", "title": "get_transaction_infoArguments", "required": [ "chain_id", "transaction_hash" ], "properties": { "chain_id": { "type": "string", "title": "Chain Id", "description": "The ID of the blockchain" }, "session_id": { "anyOf": [ { "type": "string" }, { "type": "null" } ], "title": "Session Id", "default": null, "description": "Opaque session identifier." }, "transaction_hash": { "type": "string", "title": "Transaction Hash", "description": "Transaction hash" }, "include_raw_input": { "anyOf": [ { "type": "boolean" }, { "type": "null" } ], "title": "Include Raw Input", "default": false, "description": "If true, includes the raw transaction input data." } } }arguments 46 linesget_chains_list reads unknown 13h ago
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.
{ "type": "object", "title": "get_chains_listArguments", "properties": { "query": { "anyOf": [ { "type": "string" }, { "type": "null" } ], "title": "Query", "default": null, "description": "Optional case-insensitive substring filter applied to chain name, chain ID, native currency, and ecosystem. Prefer narrow text terms over partial numeric chain IDs because matching is substring-based." }, "session_id": { "anyOf": [ { "type": "string" }, { "type": "null" } ], "title": "Session Id", "default": null, "description": "Opaque session identifier." } } }arguments 32 linesget_address_info reads unknown never probed
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 - ENS name association (if any) - Contract status (whether the address is a contract, whether it is verified) - Proxy contract information (if applicable): determines if a smart contract is a proxy contract (which forwards calls to implementation contracts), including proxy type and implementation addresses - Token details (if the contract is a token): name, symbol, decimals, total supply, etc. Essential for address analysis, contract investigation, token research, and DeFi protocol analysis.
{ "type": "object", "title": "get_address_infoArguments", "required": [ "chain_id", "address" ], "properties": { "address": { "type": "string", "title": "Address", "description": "Address to get information about" }, "chain_id": { "type": "string", "title": "Chain Id", "description": "The ID of the blockchain" }, "session_id": { "anyOf": [ { "type": "string" }, { "type": "null" } ], "title": "Session Id", "default": null, "description": "Opaque session identifier." } } }arguments 33 linesdirect_api_call reads unknown 21h ago
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).
{ "type": "object", "title": "direct_api_callArguments", "required": [ "chain_id", "endpoint_path" ], "properties": { "cursor": { "anyOf": [ { "type": "string" }, { "type": "null" } ], "title": "Cursor", "default": null, "description": "The pagination cursor from a previous response to get the next page of results." }, "method": { "enum": [ "GET", "POST" ], "type": "string", "title": "Method", "default": "GET", "description": "HTTP method used for the upstream call.

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - Prove it is yours. Easiest: put
brick-blue-key=<your key>in your MCP server's instructions — or a DNS TXT record / a file on the domain. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's id4b9a3ad6761a84b2.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
