Blockscout MCP: addresses, tokens and contracts by asking

Add Blockscout's 16 tools to your AI app

1. 1Click Connect Blockscout free. There's no sign-in, so its tools are ready at once.
2. 2Most tools read chain data, like `get_transaction_info` and `get_tokens_by_address`. `direct_api_call` reaches any raw Blockscout API endpoint and `read_contract` calls contract functions; switch either off if you want a narrower set.
3. 3Add ContextGate to your AI app as a connector or MCP server. The steps for each app are on the Works with page.
4. 4Ask your AI app what an ENS name resolves to and which tokens that address holds, then open Activity to see the `get_address_by_ens_name` and `get_tokens_by_address` calls.

Onchain research with Blockscout

• Get an enriched view of a transaction, with decoded input, using `get_transaction_info`.
• List the ERC-20 tokens and NFTs an address holds with `get_tokens_by_address` and `nft_tokens_by_address`.
• Turn an ENS name into an address with `get_address_by_ens_name`.
• Read a verified contract's ABI and source with `get_contract_abi` and `inspect_contract_code`.

Control over raw API access

• Switch off `direct_api_call` and your AI app works only through the dedicated tools.
• A policy can warn before `read_contract` or `direct_api_call` runs.
• Activity keeps every Blockscout call your team's AI apps make.

What you get with Blockscout and ContextGate

• Your AI apps can use BlockscoutClaude, Cursor, ChatGPT and other AI apps reach Blockscout through the one ContextGate connection you add to them.
• You choose which tools they can useSwitch off any Blockscout tool you don't want used. It's hidden from your AI apps and refused if called.
• Every call is checked and recordedYour policies check each call (for example, personal data is hidden and secrets are blocked), and Activity keeps a record of it.

ContextGate sees only the tool calls that go through it, not your AI app's built-in tools or your chats.
