Setup snapshot

git clone https://github.com/ManojBaasha/mcp-onchain-agent.git

1
Setup complexity is MEDIUM. Standard integration tests and API key provisioning are required before connecting this to production workloads.
2
Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

MCP Onchain Agent

A Model Context Protocol (MCP) server that integrates Coinbase AgentKit to provide AI-driven on-chain interactions through Claude Desktop and other MCP-compatible clients.

Features

MCP Server: Exposes AgentKit tools via the Model Context Protocol
Comprehensive Error Handling: Detailed logging and error messages for debugging
Multi-Client Support: Works with Claude Desktop, MCP Jam, and other MCP debuggers
CDP Integration: Uses Coinbase Developer Platform (CDP) for wallet management and on-chain operations
Testnet Utilities: Includes a utility script for requesting testnet funds

│   ├── index.ts              # MCP server entry point
│   └── getAgentKit.ts        # AgentKit configuration and initialization

├── claude_desktop_config.json    # Claude Desktop configuration (not tracked)
├── mcp_debugger_config.example.json  # Example config for MCP debuggers
└── package.json

Prerequisites

Node.js (v22+ recommended)
CDP API credentials:
- CDP_API_KEY_ID
- CDP_API_KEY_SECRET
- CDP_WALLET_SECRET

Installation

npm install

Configuration

Environment Variables

The server requires the following environment variables (set via your MCP client configuration):

Required:

CDP_API_KEY_ID - Your CDP API key ID
CDP_API_KEY_SECRET - Your CDP API key secret
CDP_WALLET_SECRET - Your CDP wallet secret

Optional:

NETWORK_ID - Network ID (default: base-sepolia)
ADDRESS - Wallet address (if using existing wallet)
OWNER_ADDRESS - Owner address for wallet
RPC_URL - Custom RPC endpoint
PAYMASTER_URL - Paymaster URL for sponsored transactions
IDEMPOTENCY_KEY - Idempotency key for requests

Usage

Building the Server

npm run build

This compiles TypeScript to JavaScript in the build/ directory.

Using with Claude Desktop

Copy claude_desktop_config.json to your Claude Desktop config directory:

cp claude_desktop_config.json ~/Library/Application\ Support/Claude/claude_desktop_config.json

Edit the config file and add your CDP credentials in the env section.
Restart Claude Desktop and start using on-chain tools!

Using with MCP Debuggers (MCP Jam, etc.)

Reference mcp_debugger_config.example.json for the configuration format.
In your MCP debugger, configure the server with:
- Command: node
- Args: ["/path/to/mcp-onchain-agent/build/index.js"]
- Environment Variables: Set all required variables in the env section
The server logs detailed startup information to stderr, which MCP debuggers can capture for troubleshooting.

Testnet Utilities

The server_wallet/ directory contains a utility script for requesting testnet funds:

cd server_wallet
npm install
# Set up .env file with CDP credentials
npx tsx main.ts

This script requests testnet tokens (ETH, USDC, EURC, CB-BTC) from Base Sepolia and Ethereum Sepolia testnets.

Development

Code Structure

src/index.ts: Main MCP server implementation
- Sets up MCP server with stdio transport
- Handles tool listing and execution
- Provides detailed error logging
src/getAgentKit.ts: AgentKit configuration
- Initializes CDP Smart Wallet Provider
- Configures action providers (ERC20, WETH, Pyth, etc.)
- Handles environment variable validation
- Provides helpful error messages

Error Handling

The server includes comprehensive error handling:

Startup Logging: Logs each initialization step to stderr
Environment Validation: Checks for required environment variables
Structured Errors: JSON-formatted error output for debuggers
Helpful Messages: Clear error messages with troubleshooting guidance

Debugging

When the server fails to start, check the stderr output for:

Starting MCP server... - Server initialization begins
Initializing AgentKit... - AgentKit configuration starts
Environment check: - Shows which environment variables are set (without exposing secrets)
Error messages with specific details about what went wrong

Available Tools

The server exposes AgentKit tools via MCP, including:

Wallet operations (balance checks, transfers)
ERC20 token operations
WETH operations
Pyth price feeds
CDP API operations
Smart wallet operations
X402 operations

See AgentKit Documentation for full tool documentation.

Troubleshooting

"Connection closed" Error

This usually means environment variables aren't being passed correctly:

Verify all required environment variables are set in your MCP client configuration
Check the stderr logs for the "Environment check" output
Ensure ADDRESS and OWNER_ADDRESS are either set correctly or left empty (not "value")

"Smart Account with given address not found"

The wallet at the specified address doesn't exist. Either:

Create the wallet first using CDP
Remove the ADDRESS environment variable to let the provider create/find a wallet
Use a different address where a wallet exists

"Missing required environment variables"

Ensure all three required variables are set:

CDP_API_KEY_ID
CDP_API_KEY_SECRET
CDP_WALLET_SECRET
