What is mcp-client-demo CLAUDE.md?

Project guidance for a Next.js web app that demonstrates Web3 features on Shape Network, a blockchain network. It describes the app's commands, structure, technologies, supported networks, and wallet connection setup.

Use it when developing, checking, formatting, or building this Shape Network app, including its React interface, wallet connections, blockchain data fetching, and network configuration.

It helps coding agents understand how the application is organised and which commands and settings govern its development. This reduces mistakes when changing blockchain, wallet, or user-interface code.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5	$0.00568	$0.00568
Opus 5	$0.00284	$0.00284
Sonnet 5	$0.00114	$0.00114
Haiku 4.5	$0.00057	$0.00057

Security

Grade A, and why

mcp-client-demo CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Architecture Overview

This is a Next.js 15 app with App Router that demonstrates Web3 integration with Shape Network. The application is built as a modern dApp with:

Core Stack

Next.js 15 with App Router and React 19
TypeScript for type safety
Tailwind CSS with Shadcn/ui component library
Web3 Integration via Wagmi v2 and RainbowKit
React Query for data fetching and caching

Web3 Configuration

Supports Shape Mainnet (chainId: 360) and Shape Sepolia (chainId: 11011)
Uses Alchemy SDK for blockchain interactions
Wallet connection handled by RainbowKit with WalletConnect support
Chain configuration in lib/web3.ts with HTTP transports for each network

Key Components Architecture

components/providers.tsx - Root providers wrapper (WagmiProvider, QueryClient, RainbowKitProvider)
lib/config.ts - Environment variable configuration
lib/clients.ts - Alchemy client setup
hooks/ - Custom React hooks for Web3 operations and mobile detection
components/ui/ - Shadcn/ui component library (extensive set of pre-built components)

Application Structure

The main page (app/page.tsx) renders three key components:

McpStatusPanel - MCP (Model Context Protocol) status monitoring
AnalyticsDashboard - Data visualization dashboard
ShapeNftViewer - NFT display component

Environment Requirements

Required environment variables:

NEXT_PUBLIC_ALCHEMY_KEY - Alchemy API key
NEXT_PUBLIC_WALLET_CONNECT_PROJECT_ID - WalletConnect project ID
NEXT_PUBLIC_CHAIN_ID - Target chain ID (360 for Shape Mainnet, 11011 for Shape Sepolia)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
