# Blockscout — AI Connector Blockscout publishes 15 MCP tools to Claude. Marketplace availability, tool surface, verification tier, and what Node8 measured against the live endpoint. Source: https://node8.ai/ai-connectors/finance/blockscout/ --- [AI Connectors](https://node8.ai/ai-connectors/) · [Finance](https://node8.ai/ai-connectors/finance/) # Blockscout Multichain block explorer data: addresses, tokens, and contracts Listed in Claude · 15 published tools · Verified partner [Claude connector docs](https://github.com/blockscout/mcp-server) [blockscout.com](https://www.blockscout.com/) Overview ## What Blockscout does Blockscout indexes blockchain data across many chains, and the connector exposes explorer reads over it: block metadata by height or timestamp, native transfers and internal calls for an address, ERC-20 transfers over a time range, token holdings with market data attached, NFTs grouped by collection, decoded transaction detail, and verified contract source and ABI. ENS names resolve to addresses and token symbols resolve to contract addresses. Chain selection is explicit, with a tool that returns supported chain IDs. Fifteen tools are listed and sixteen answered. ### Who it is for Onchain analysts and smart contract developers investigating addresses and transactions. ### Tool surface The surface is read-oriented explorer data with two escape hatches: \`read\_contract\` runs view calls or simulates them through eth\_call, and \`direct\_api\_call\` reaches raw Blockscout endpoints for chain-specific data. A session-priming \`\_\_unlock\_blockchain\_analysis\_\_\` tool accounts for the sixteenth entry against fifteen claimed. Availability ## Where Blockscout is listed Blockscout is listed in the Claude connectors directory only. Blockscout has no app under the same domain in the ChatGPT directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them. The MCP server behind a Claude connector is usually the same server a ChatGPT app would need, so the absence is a distribution decision rather than a technical one. Claude listing ## In the Claude connectors directory Blockscout publishes 15 tools to Claude. That is a mid-sized surface: 59.4% of the 1,253 Claude-listed connectors expose fewer. The median Claude-listed connector filed under Finance publishes 12, so this one runs 3 tools above its bucket's median and ranks 63rd of 159 by tool count. It falls in the 11-20 tools band, which holds 22.5% of the Claude directory. ### Measured against the live endpoint A direct call to the endpoint returned 16 tools, 1 more than the 15 the listing publishes. Probed 2026-08-07. #### Tools the server actually returns - `__unlock_blockchain_analysis__` - `get_block_info` - `get_block_number` - `get_address_by_ens_name` - `get_transactions_by_address` - `get_token_transfers_by_address` - `lookup_token_by_symbol` - `get_contract_abi` - `inspect_contract_code` - `read_contract` - `get_address_info` - `get_tokens_by_address` - `nft_tokens_by_address` - `get_transaction_info` - `get_chains_list` - `direct_api_call` Blockscout publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally. Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there. Publisher Blockscout Verification Verified partner (37.8% of the Claude directory) Filed under Financial Services Endpoint `https://mcp.blockscout.com/mcp` Documentation [Publisher setup docs](https://github.com/blockscout/mcp-server) Published tools 15 · 11-20 tools band Depth rank in Finance 63 of 159 Snapshot August 2026 Blockscout carries partner verification in the Claude directory, which 474 of 1,253 listings do (37.8%). That is a review step past self-publishing, not an Anthropic-built server. In the publisher's words ## How Blockscout describes it > Provides access to multichain blockchain data such as balances, tokens, NFTs, contract metadata for contextual analysis. Quoted from the connector's own Claude directory listing as captured in August 2026. Node8 did not write it and does not vouch for it.
