Boar blockchain MCP (advanced)

Server Details

Free, keyless MCP server with 50 read-only blockchain tools for Bitcoin, Ethereum, and Mezo. No installation, no API key required -- just add the URL to your MCP client and start querying balances, transactions, blocks, ENS names, ERC-20 tokens, smart contracts, and more. Runs on Cloudflare's global edge network via Streamable HTTP. All tools are strictly read-only and stateless.

eth_callInspect

Execute a read-only smart contract call on Ethereum mainnet. Returns the hex-encoded return data. Use this to read contract state without sending a transaction.

ParametersJSON Schema

Name	Required	Description
`to`	Yes	Contract address
`data`	Yes	ABI-encoded function call data
`from`	No	Sender address (optional, for context)
`block`	No	Block to query (default: latest)

eth_decode_calldataInspect

Decode raw calldata into function name and typed arguments using a provided ABI on Ethereum mainnet. Pure computation — no RPC call needed. Pass the hex calldata from a transaction input or eth_call.

ParametersJSON Schema

Name	Required	Description	Default
`abi`	Yes	Contract ABI as a JSON array of ABI items, or a JSON-encoded string of that array
`calldata`	Yes	Raw calldata (0x-prefixed hex)

eth_decode_logInspect

Decode a raw event log (topics + data) into named fields using a provided ABI on Ethereum mainnet. Pure computation — no RPC call needed. Pass topics and data from a transaction receipt log entry.

ParametersJSON Schema

Name	Required	Description
`abi`	Yes	Contract ABI as a JSON array of ABI items, or a JSON-encoded string of that array
`data`	Yes	Log data field (0x-prefixed hex, ABI-encoded non-indexed event parameters)
`topics`	Yes	Log topics array. topics[0] is the event signature hash (keccak256 of the event signature)

eth_decode_returnInspect

Decode raw return data from an eth_call into typed values using a provided ABI and function name on Ethereum mainnet. Pure computation — no RPC call needed.

ParametersJSON Schema

Name	Required	Description
`abi`	Yes	Contract ABI as a JSON array of ABI items, or a JSON-encoded string of that array
`data`	Yes	Raw return data (0x-prefixed hex)
`function_name`	Yes	Name of the function whose output types to decode against

eth_decode_revertInspect

Decode raw EVM revert data from a failed transaction or eth_call on Ethereum mainnet. Handles Error(string) reverts, Panic(uint256) assertions, custom Solidity errors (requires ABI), and silent reverts. Pure computation — no RPC call needed. Pass the hex revert data from a transaction receipt or eth_call error response.

ParametersJSON Schema

Name	Required	Description	Default
`abi`	No	Contract ABI for decoding custom errors. Pass as a JSON array of error definitions (or as a JSON-encoded string of that array). Only needed for custom errors beyond the built-in Error(string) and Panic(uint256).
`revert_data`	Yes	Raw revert data as hex (0x-prefixed). Use "0x" or empty string for a silent revert.

eth_encode_calldataInspect

Encode a function call into ABI-encoded calldata hex. Accepts either a human-readable function signature (e.g. 'transfer(address to, uint256 amount)') or a full ABI JSON array plus function name. Pass uint/int values as decimal strings to avoid JS number precision loss. Pure computation — no RPC call needed.

ParametersJSON Schema

Name	Required	Description
`abi`	No	Full ABI as a JSON array (or JSON-encoded string). Use with function_name.
`args`	No	Arguments array. Pass uint/int values as decimal or hex strings for precision.
`signature`	No	Human-readable function signature, e.g. 'transfer(address to, uint256 amount)'. Use instead of abi+function_name.
`function_name`	No	Function name — required when using abi instead of signature

eth_multicallInspect

Batch multiple read-only contract calls into a single RPC round trip via Multicall3 on Ethereum mainnet (0xcA11bde05977b3631167028862bE2a173976CA11). Returns success status and raw return data for each call. Use allowFailure=true to prevent one failed call from aborting the whole batch.

ParametersJSON Schema

Name	Required	Description	Default
`calls`	Yes	Array of calls to batch (at least 1)

mezo_callInspect

Execute a read-only smart contract call on Mezo. Returns the hex-encoded return data. Use this to read contract state without sending a transaction.

ParametersJSON Schema

Name	Required	Description
`to`	Yes	Contract address
`data`	Yes	ABI-encoded function call data
`from`	No	Sender address (optional, for context)
`block`	No	Block to query (default: latest)

mezo_decode_calldataInspect

Decode raw calldata into function name and typed arguments using a provided ABI on Mezo. Pure computation — no RPC call needed. Pass the hex calldata from a transaction input or eth_call.

ParametersJSON Schema

Name	Required	Description	Default
`abi`	Yes	Contract ABI as a JSON array of ABI items, or a JSON-encoded string of that array
`calldata`	Yes	Raw calldata (0x-prefixed hex)
