# OKLink MCP for AI Agents AI Agent Connect > OKLink MCP gives your AI agent real-time access to multi-chain blockchain data. You can query wallet balances, transaction histories, token metrics, and NFT collection details across networks like Ethereum, BSC, and Bitcoin without jumping between different block explorers. ## Overview - **Category:** developer-tools - **Price:** Free - **Endpoint:** https://edge.vinkius.com/vk_preview_rG2qoQ6wtSF0Dt1yexbvFZkxc0fDXRtdOQHtruCL/ai-agent-connect - **Tags:** web3-data, multi-chain, blockchain-explorer, crypto-api, on-chain-analysis ## Description The OKLink MCP lets you pull live blockchain data from dozens of networks like Bitcoin, Ethereum, and BSC directly into your AI client. If you're tired of jumping between different block explorers to track a single wallet, this tool handles the cross-chain research for you. You can ask your agent to summarize a specific address, pull a full history of every transaction it's made, or check the current balance of specific tokens. It also lets you dig into the details of individual transactions or get data on NFT collections. By connecting this through the Vinkius catalog, you turn your AI into a dedicated blockchain analyst. It takes the manual work out of verifying on-chain movements and lets you focus on the actual data instead of clicking through tabs. ## Tools ### get_latest_block Get the most recent block information for a specific chain. It's useful for checking the current state of the network. ### get_nft_collection_info Get information about a specific NFT collection. Use this to pull data on specific projects and assets. ### get_supported_chains Get a summary of all blockchains currently supported. This tells you which networks your agent can reach. ### get_token_balance Get the current token balances for a specific address. Use this to quickly check holdings across different chains. ### get_token_detail Get detailed information about a specific token. This helps you see the metrics and specs for any given asset. ### get_token_list See a list of all tokens on a specific blockchain. Use this to find available assets on a new network. ### get_transaction_detail Pull the specific details for a single transaction hash. This helps you see the status and gas fees for any movement. ### get_address_summary Get a high-level summary for a specific wallet or contract. It's the fastest way to see an address's overall activity. ### get_address_transactions Retrieve a full list of transactions for a specific address. Use this to audit every movement a wallet has made. ### get_block_detail Get detailed information about a specific block. This is great for deep dives into network activity. ### get_block_transactions See every transaction contained within a specific block. Use this to analyze what happened in a specific network update. ### get_chain_info Get detailed information about a specific blockchain. This helps you understand the technical specs of a network. ## Prompt Examples **Prompt:** ``` What's the balance of 0x742d35Cc6634C0532925a3b844Bc454e4438f44e on Ethereum? ``` **Response:** ``` I've checked that address for you. It currently holds: **12.5 ETH** and a total of **150 transactions**. Would you like me to pull the full transaction history or check specific token balances? ``` **Prompt:** ``` What's the latest block on Polygon? ``` **Response:** ``` The latest block on Polygon (MATIC) is currently at height **64,231,890**. It was updated just a few seconds ago. I can pull the list of transactions included in this block if you'd like to see the latest activity. ``` **Prompt:** ``` Give me the details for transaction 0x5c504ed432cb51138bcf09aa5e8a410dd4a1e204ef84bfed1be16dfba1b22026. ``` **Response:** ``` I've analyzed that transaction. Here's the summary: - **Status**: Success - **Type**: Transfer of 500 USDC - **Block**: 18,402,100 - **Gas Fee**: 0.002 ETH ``` ## Capabilities ### Fetch wallet balances Get the current token holdings for any specific on-chain address. ### Pull transaction history Retrieve a full list of past movements for a wallet or contract. ### Inspect transaction details See the gas fees, status, and specific data for a single transaction hash. ### Check block data View the latest block height and the specific transactions included in it. ### Research NFT collections Get detailed metrics and info on specific NFT projects. ### List supported chains See every blockchain the API can currently reach. ## Use Cases ### Whale Tracking A researcher wants to see if a large wallet moved funds. They ask the agent to summarize the address activity. ### Transaction Debugging A dev has a failed tx hash. They ask the agent for the specific gas fees and status to find the error. ### Portfolio Audit A trader wants to know their total holdings. The agent pulls balances for multiple tokens across chains. ### New Chain Research A user wants to know which chains are supported. The agent lists them all instantly to guide their next move. ## Benefits - Stop manual searching: Use get_address_summary to see wallet activity instantly instead of browsing block explorers. - Cross-chain visibility: Query data across Bitcoin, Ethereum, and BSC using get_supported_chains in one place. - Deep transaction auditing: Pull every single movement with get_address_transactions to spot patterns. - Real-time token tracking: Monitor holdings with get_token_balance to stay on top of portfolio changes. - NFT project research: Get collection metrics with get_nft_collection_info to evaluate projects faster. - Accurate block analysis: Inspect specific network activity using get_block_detail for precise data. ## How It Works The bottom line is your AI gets a direct line to multi-chain blockchain data without you needing to copy-paste from websites. 1. Subscribe to the OKLink MCP on Vinkius. 2. Add your OKLink Access Key to the configuration. 3. Ask your AI client to pull data like 'What's the balance of this address?' ## Frequently Asked Questions **Can the OKLink MCP track wallets on multiple blockchains?** Yes, it supports dozens of networks including Bitcoin, Ethereum, and BSC. You can query any supported chain from one place. **How does the OKLink MCP help with NFT research?** It can pull specific data on NFT collections, making it easy to get metrics without manual searching. **Can I use the OKLink MCP to see my current token balances?** Yes, the Connector allows your agent to check balances for specific addresses across various networks. **Does the OKLink MCP provide transaction history?** It can retrieve a full list of transactions for any wallet or contract you provide. **Can the OKLink MCP help me debug a failed transaction?** You can pull the specific details of any transaction hash to see the status and gas fees. **Is the OKLink MCP good for tracking whale movements?** It's ideal for that because it can summarize address activity and pull full histories quickly. **How do I check the balance of a specific wallet address?** You can use the `get_address_summary` tool by providing the chain name (e.g., 'eth') and the address. For a detailed list of all token holdings, use the `get_token_balance` tool. **Can I retrieve information about NFT collections?** Yes! Use the `get_nft_collection_info` tool with the chain name and the NFT contract address to fetch metadata and collection details. **How do I find the latest block on a specific blockchain?** Simply use the `get_latest_block` tool and specify the chain (e.g., 'btc', 'eth', 'polygon'). It will return the height and details of the most recently mined block.
