Conflux MCP for AI. Audit core and eSpace contract states instantly.

Q: How do I check the balance of an address on Core Space? (cfxgetbalance)

You run cfxgetbalance and provide the target address. The MCP returns the current CFX amount for that account directly in your chat.

Q: Is there a way to see if a transaction will fail before I send it? (ethestimategas)

Yes, use ethestimategas. This function calculates the required gas and collateral for an eSpace operation so you can verify costs without making a real change.

Q: Can I get all block details by epoch number? (cfxgetblockbyepochnumber)

Yes, cfxgetblockbyepochnumber lets you pull the full data set for a specific time slice of blocks on Core Space. This is great for deep historical analysis.

Q: How do I debug transaction failures? (cfxgettransactionreceipt)

Run cfxgettransactionreceipt with the hash. It gives you the full receipt, letting you see if the transaction failed and why it couldn't complete.

Q: How do I check the current operational status and client version using cfxgetstatus?

Running cfxgetstatus provides immediate node details. This tool returns the current epoch number, synchronization state, and the specific Conflux Core client version in one call, confirming network health.

Q: What is the proper procedure for sending a pre-signed transaction using cfxsendrawtransaction?

You must use cfxsendrawtransaction when you've generated and signed the data externally. This method bypasses needing the node to manage the sender account keys directly, giving you granular control.

Q: Before I submit a transaction, how do I get the next available nonce for an address using cfxgetnextnonce?

First, call cfxgetnextnonce to confirm the account's current sequence number. You must use this exact nonces value when constructing your signed transaction payload to ensure validity.

Q: How can I filter specific event logs or data from Core Space using cfxgetlogs?

You can use cfxgetlogs and specify a filter based on the target address, contract signature, or topic. This helps isolate exactly which data packets were emitted during a complex smart contract execution.

The Pain of Checking Blockchain States

Right now, checking the state of a contract means opening your browser. You navigate to an explorer, paste in an address, switch tabs to check gas usage, and then maybe open another tab just for block hashes. It's copy-pasting addresses and reading through dozens of pages of technical jargon until you find the single number you need.

With this MCP, your agent takes all that data—the account summary from `cfx_get_account`, the current node status via `cfx_get_status`, even potential gas costs using `cfx_estimate_gas_and_collateral`—and compiles it into a single, conversational answer. It's immediate.

Getting Transaction Data with Conflux

Before this MCP, tracking was manual: you had to find the transaction hash first, then open the explorer just to see the basic details. If you needed the actual execution outcome—the receipt or logs—you were deep in another set of tabs and clicking through multiple endpoints.

Now, your agent can get you the full story. You request a block by hash using `cfx_get_block_by_hash`, and it pulls out every relevant detail, letting you debug what happened instantly. It's just that simple.

Here's how it actually works

The bottom line is, your AI client handles all the complex API calls and formatting so you just get an answer.

First, subscribe to this MCP and provide your Conflux Core and eSpace RPC URLs.

Next, prompt your AI client with a specific request, like 'What is the balance for address X?'

Your agent invokes the necessary tool (e.g., cfx_get_balance), retrieving raw blockchain data that it then presents to you in natural language.

Who is this actually for?

Blockchain developers who waste time context-switching between IDEs and block explorers. Data analysts needing raw, verifiable network logs for reports. Crypto power users who need to monitor multiple accounts quickly.

Smart Contract Developer

Debugging failed calls by running cfx_call or checking transaction receipts using cfx_get_transaction_receipt without leaving their coding environment.

Data Analyst

Pulling specific epoch data and logs from both Core Space and eSpace for off-chain reporting using simple prompts.

DevOps Engineer (Web3)

Monitoring the overall health of a deployed contract by checking sponsorship details with cfx_get_sponsor_info or node status via cfx_get_status.

What Changes When You Connect

You stop having to jump between block explorers. By using cfx_get_account, you get a full state summary directly in your conversation, allowing immediate verification of an account's worth and current status.

The gas estimation process is simplified. Instead of manually calculating potential costs, running cfx_estimate_gas_and_collateral gives you the exact required collateral before you ever attempt to send a transaction.

Debugging failed smart contract calls gets easier. You can run a read-only simulation using eth_call on eSpace or check execution logs with cfx_get_logs, pinpointing exactly where the logic broke down.

Monitoring network health is instant. Need to know if the node is online? Use cfx_get_status. It's a single prompt that gives you everything from client version (cfx_client_version) to synchronization status.

Sending transactions becomes safer. You can check the next nonce with cfx_get_next_nonce and then use cfx_send_transaction, knowing your account hasn't been double-spent because of stale data.

See it in action

01 01

Investigating a Failed Smart Contract Call

A developer sees an unexpected failure. Instead of manually fetching logs and receipts, they ask their agent to run cfx_get_transaction_by_hash first, then check the detailed receipt using cfx_get_transaction_receipt. The agent instantly identifies whether the issue was insufficient gas or a contract logic error.

02 02

Comparing Core vs. eSpace Data

A researcher needs to compare balances across two networks. They prompt their agent to run cfx_get_balance for an address on Core Space, and immediately follow up by asking the same thing for eSpace using eth_get_balance. The results appear side-by-side in one chat window.

The honest tradeoffs

Assuming Data Consistency

Anti-pattern

A user runs a successful transaction, but assumes the state is finalized. They might forget to check the cfx_get_transaction_receipt and assume success when it's actually pending or failed.

The Fix

Always follow up any write operation with an attempt to retrieve the full receipt using cfx_get_transaction_receipt. This confirms not just that the transaction was sent, but also how the network processed the state change.

Mixing Up Network Layers

Anti-pattern

Trying to check a Core Space balance using eSpace functions (like eth_get_balance). The tool will fail or return garbage because the networks are distinct.

The Fix

Be specific. Use cfx_ tools for Core Space data and eth_ tools for eSpace data. Don't assume they talk to each other.

When It Fits, When It Doesn't

Use this MCP if your task involves reading, writing, or simulating activity across the Conflux network layers (Core Space and eSpace). Specifically, you need reliable functions like cfx_get_balance for state auditing or eth_estimate_gas before executing a write operation. Don't use it if you simply want to read basic information that could be found on a public block explorer website; those tools are overkill. If your goal is just querying data from an external, non-blockchain API (like a mailing list or a database), stick with general utility MCPs instead.

Questions you might have
