Works with Claude, ChatGPT, Cursor, and more
The Model Context Protocol standardizes how applications expose capabilities to LLMs. Instead of operating in isolation, your AI gains direct access to external platforms, live data, and real-world actions through secure, standardized connections.
This connection provides 21 powerful capabilities that interface natively with Claude, ChatGPT, Cursor, and other compatible AI platforms. No middleware. No custom integration required.
Manually tracking blockchain history feels like archaeology.
Right now? You're copy-pasting transaction hashes from one explorer, opening a second tab for the token contract ABI, and then running a third query just to see if the state change was actually successful. It’s slow, it’s painful, and you always risk missing a key detail between tabs.
With this MCP server, you ask your agent: "What happened with asset X?" The system runs `get_erc20_transfers`, checks the contract ABI via `get_contract_abi`, and confirms the final result using `check_transaction_receipt_status`. You get a clean answer in one chat turn.
Snowtrace (Avalanche Explorer) MCP Server: Get verifiable, live data.
Manual checks require you to verify the contract's source code against its deployed bytecode using `verify_source_code`. You have to manually ensure that what was written is what runs. It’s a multi-step audit process every time.
Now, your agent handles it. You just ask if the contract logic matches the source code you expect. The system uses `get_contract_source_code` and validates it automatically. No more manual cross-referencing needed.
What your AI can actually do with this
Snowtrace connects the full power of the Avalanche C-Chain straight into your AI client. You can check everything—from token balances to how smart contracts actually work—right in your chat window.
Address Balance & Network Metrics:
You'll get AVAX balances for a single address using get_avax_balance, or you can calculate the combined AVAX balance for up to twenty addresses with get_avax_balance_multi. To track market movement, use get_avax_last_price to grab the most recent trading price data against fiat or other major currencies. You can also run get_avax_total_supply to see the total amount of circulating supply available for AVAX.
For network timing, get_block_countdown gives you an estimate of how many seconds are left until the next block is mined. To look back in time, use get_block_number_by_time to determine what block number was active at a specific historical timestamp. If you need to know about rewards, get_block_reward retrieves the amount of AVAX awarded to miners or validators for the current block.
Token Transfer Tracking (ERC-20/NFT):
You can audit all token movements. Use get_erc20_transfers to list records of every transfer involving ERC-20 fungible tokens between addresses, and get_token_balance gets the current balance for a single address for a specific ERC-20 token. If you want to know the total supply of an ERC-20 token, run get_token_total_supply.
For non-fungible assets, get_erc721_transfers tracks and lists all transfer events for those ERC-721 NFTs. You can also get a list of all block numbers that were mined by a specific blockchain address using get_mined_blocks, while get_normal_transactions fetches standard, user-initiated transactions for an address over time.
Contract Logic Analysis:
Understanding contract code is straightforward with this toolset. You can use get_contract_source_code to retrieve the human-readable source code for a verified smart contract address. If you need to know what functions the contract supports, get_contract_abi gets the Application Binary Interface (ABI) detailing those functions. For deep dives into complex logic, get_internal_transactions shows internal calls made by a contract, which is useful for tracing function flow.
Finally, verify_source_code confirms that the source code you provide matches the compiled bytecode on the chain.
Transaction History & Status Checks:
You can check transaction results thoroughly. Use get_transaction_receipt_status to verify the final outcome status of any given transaction receipt on the chain, and check_contract_execution_status confirms if a smart contract's attempt to run finished successfully or failed. To see general activity, get_logs retrieves all event logs emitted during transactions or state changes on the chain.
Block and Time Mapping:
The network functions give you context. You can determine what block number was active at any time using get_block_number_by_time. This entire suite lets your agent handle complex blockchain queries by pulling in everything from token movements to underlying contract structure, all without leaving your chat window.
019e38f0-3c4d-7392-bdf0-ffc5aa28c990 Here's how it actually works
The bottom line is that your AI client acts as a dedicated blockchain node for Avalanche, letting you run complex queries without writing code or leaving the chat.
Subscribe to the Snowtrace server on Vinkius and enter your API key.
Ask your AI client for blockchain data (e.g., "What is the ERC-20 balance of this address?").
The agent calls the necessary tools, retrieves structured data from the Avalanche C-Chain, and presents the answer in plain text.
Who is this actually for?
Anyone working with decentralized finance (DeFi) needs this. If you're an auditor who has to manually cross-reference transaction hashes and contract logic, or a developer debugging failed deployments, this saves hours of API calls. It’s for people who need verifiable, real-time on-chain facts.
Debugging smart contract failures; fetching ABIs using get_contract_abi or checking execution status with check_contract_execution_status.
Aggregating token transfer data across multiple addresses to research market trends and wallet activity.
Reviewing historical transaction records (get_normal_transactions) against contract source code (get_contract_source_code) to validate funds movement.
What Changes When You Connect
See all asset movements immediately. You track every ERC-20 transfer using get_erc20_transfers or monitor NFT sales with get_erc721_transfers, eliminating manual explorer tabs.
Debug contracts on the fly. Get the full source code and ABI via get_contract_source_code and get_contract_abi. You instantly know what a protocol is designed to do, without guessing.
Audit transaction failures. Instead of just seeing 'failed,' you use check_transaction_receipt_status to confirm why the contract execution failed or if it was due to gas limits.
Batch balance checks are fast. Use get_avax_balance_multi to check up to 20 wallets at once, saving dozens of individual API calls and time.
Understand the network depth. You can map timestamps to block numbers using get_block_number_by_time, giving you a precise historical anchor point for any research.
See it in action
Tracing Missing Funds
A user spots an unusual transfer. They ask the agent to use get_erc721_transfers and then cross-reference those transaction hashes using get_internal_transactions. The agent reveals that the NFT was passed through a specific contract, solving the mystery of where the funds went.
Vetting New DeFi Protocols
A developer needs to trust a new lending protocol. They ask the agent to use get_contract_source_code and then run verify_source_code. If the code verification passes, they can proceed with confidence; otherwise, they know not to touch it.
Compiling Portfolio Value
A data analyst needs a snapshot of 15 different wallets. Instead of running 15 separate balance checks, they ask the agent to use get_avax_balance_multi. They get the full portfolio value instantly, allowing them to finish their report early.
Debugging State Changes
A user sees a contract's state changed but doesn't know why. They ask for get_logs and then check the associated transactions using get_normal_transactions. The agent combines these logs to pinpoint the exact function call that triggered the state change.
The honest tradeoffs
Checking balances in chunks
Running 10 individual calls for ten different addresses using get_avax_balance one by one. This is slow, hits rate limits fast, and takes forever.
Use the multi-address tool: run a single query with get_avax_balance_multi listing all 10 addresses. It's faster, cleaner, and keeps your agent conversation flowing.
Trusting one source of truth
Seeing that an address has tokens (get_token_balance) but assuming the contract is safe because it was deployed recently.
Always check the underlying code. Run get_contract_source_code and, if possible, use check_verify_status first. Never trust a balance without validating the source logic.
Forgetting transaction context
Getting a list of transactions (get_normal_transactions) but not knowing why one failed or where its money went.
Always follow up with check_transaction_receipt_status to confirm success. If it fails, use get_internal_transactions to see which specific contract call was the point of failure.
When It Fits, When It Doesn't
Use this server if your workflow requires verifiable, immutable facts about on-chain activity. This is a specialized auditing tool—not a general data dashboard. You must use it when you need to cross-reference: 1) The contract's function (Source Code/ABI), 2) the asset movement (ERC-20/NFT Transfers), and 3) the final result (Transaction Status). Don't use this if all you want is a high-level summary of market trends; better alternatives exist for that. But if your job involves debugging, auditing, or verifying complex DeFi interactions, this suite of tools is essential because it forces you to combine multiple layers of data checks.
Questions you might have
How do I check the balance of many wallets using get_avax_balance_multi? +
You pass a list of up to 20 wallet addresses in one query. This tool aggregates all balances, so you only need one call instead of running get_avax_balance repeatedly.
What is the difference between get_normal_transactions and get_internal_transactions? +
get_normal_transactions shows transactions initiated by a user's wallet. get_internal_transactions tracks calls made by a smart contract to other contracts, which is key for understanding complex DeFi logic.
Do I need get_contract_source_code if I already have the ABI? +
No, they are different. The ABI (get_contract_abi) tells you what functions exist (inputs/outputs), but the source code (get_contract_source_code) shows you how those functions work.
If I run a transaction, how do I know if it really went through? +
Always follow up with check_transaction_receipt_status. This tool gives the definitive answer on whether the blockchain accepted and processed the transaction successfully.
What happens if I run many queries with get_normal_transactions in a short time? +
You might hit rate limits. The server enforces usage caps to prevent abuse, so watch out for 429 errors. If you see one, slow down your requests and implement an exponential back-off strategy.
When using get_erc20_transfers, can I filter the results by a specific contract address? +
Yes, most transfer tools allow filtering. You typically pass the target contract's unique address as a required parameter. This narrows down the event data to only tokens from that source.
How do I know if my API key is set up correctly before querying get_avax_balance? +
If you get an authentication error (usually a 401 status), your key isn't working. Double-check that the key hasn't expired and that the server connection string in your agent is correct.
Does check_contract_execution_status differentiate between logic failures and network issues? +
It does. The status code reveals if the failure was due to insufficient gas (a contract logic fault) or a different type of transaction rejection, letting you pinpoint the exact problem.
Can I check the balance of multiple Avalanche addresses at once? +
Yes. Use the get_avax_balance_multi tool and provide a comma-separated list of up to 20 addresses to get all balances in a single response.
How do I track specific token movements like USDT or NFTs? +
You can use get_erc20_transfers for standard tokens or get_erc721_transfers for NFTs. You can filter by wallet address or specific contract address to narrow down the results.
Is it possible to see the source code of a verified contract? +
Absolutely. The get_contract_source_code tool retrieves the verified Solidity source code and metadata for any contract address that has been verified on Snowtrace.
