I will build a custom mcp server or ai agent for your web3 project

About this gig
I build MCP (Model Context Protocol) servers and autonomous AI agents that give Claude and other AI assistants real access to on-chain data and Web3 actions.
Proof of work, not just promises: multichain-tax-mcp is a published npm package giving AI agents real-time crypto tax data across 5 chains (Stacks, Celo, Base, Solana, BNB) 6 tools, FIFO/LIFO PnL engine, Form 8949-ready reports, subscription-based monetization. Featured on LaunchBuff and Product Hunt.
CeloBank Agent is an ERC-8004 verified on-chain AI agent with 21 MCP tools and x402 crypto payment support, running in production on Celo mainnet.
What I can build for you:
- Custom MCP servers exposing your API, database, or on-chain data to Claude/GPT
- Autonomous AI agents that read and act on blockchain data
- Multi-chain data integrations (transaction history, balances, DeFi positions)
- Subscription/monetization layer for your MCP tools if needed
Everything is tested, documented, and built to run in production not a proof of concept.
25+ open source projects on GitHub (@wkalidev). Let's talk about what you're building.

FAQ
What's an MCP server, and why would I need one?
MCP (Model Context Protocol) lets AI assistants like Claude access real, live data instead of relying only on training knowledge. If you want an AI agent that can check on-chain data, query your API, or take real actions, an MCP server is how you make that happen.
Can I see a real example before ordering?
Yes — multichain-tax-mcp is a live, published npm package you can test yourself. It's a working MCP server with real users, not a demo project.
