## Documentation

## What Block402 does

Block402 connects AI agents to Bitcoin and Ethereum RPC functionality through the Model Context Protocol. The listing identifies 44 available tools, but does not provide their individual names, input schemas, outputs, or operation coverage. Developers should therefore treat the tool count as the supported scope and consult the project at block402.xyz for the exact interface before building against it.

The Block402 MCP server also supports x402 payments using USDC on Base mainnet. This places it in the Finance & Fintech category for applications that combine agent-driven blockchain operations with a payment flow on Base. The supplied information does not explain whether payments are required for all tools, which operations are paid, or how payment authorization is handled.

## Tools and capabilities

The Block402 MCP server provides two stated capability areas:

- Bitcoin RPC access for AI agents.
- Ethereum RPC access for AI agents.
- A total of 44 MCP tools.
- x402 payments denominated in USDC on Base mainnet.

These descriptions establish network and payment support, but not specific blockchain methods. The material does not confirm whether the tools read chain data, submit transactions, manage wallets, estimate fees, or perform other operations. Avoid assuming those functions without checking the current project documentation.

## Setup and configuration

No README or setup instructions were provided with this listing. The available information does not identify a package, launch command, transport mode, required credentials, environment variables, wallet configuration, or client-specific setup. Visit block402.xyz for current installation and configuration details before deploying the Block402 MCP server.

The same limitation applies to payment configuration. Although x402 payments in USDC on Base mainnet are stated, the listing does not say how an agent supplies funds, selects a payer, configures a wallet, or responds to payment requests. Those details are necessary for a production integration and should be verified from the source.

## Limitations and notes

Block402 is documented here only at a high level because its README was unavailable. The confirmed facts are its Bitcoin and Ethereum RPC focus, its 44-tool count, and x402 payments in USDC on Base mainnet. Client compatibility, licensing, supported RPC methods, authentication, transaction safety, rate limits, and operational requirements are not specified. Confirm each of these before selecting the Block402 MCP server for an agent workflow.
