Pick a recipe or import any smart contract. Deploy a hosted MCP server your AI agents can call. No code, no infrastructure.

How it works
From recipe to live MCP server in four steps
Pick a recipe. Paste a contract address. Deploy. Your MCP server is live in under two minutes.
Building it yourself
- 1Install the MCP SDK and learn the transport protocol spec
- 2Parse each contract ABI and write a tool definition per function
- 3Encode calldata for write functions; handle input validation
- 4Set up Streamable HTTP and SSE transport on a server
- 5Deploy infrastructure, configure TLS, monitor uptime
- 6Repeat for every chain, every contract upgrade, every new tool
2-5 days per contract, then maintain it forever.
Choose
Choose a recipe
Start with a recipe built for your use case: DeFi yield, liquidation monitoring, DAO governance, trading, analytics, or security. Each recipe pre-configures the tools, prompts, and resources your agents need.

Import
Import your contract
The wizard asks for your contract address. ABI is auto-fetched from Etherscan, Sourcify, or Solscan. You can also upload your own JSON. Multi-proxy contracts and EIP-1967 proxies are handled automatically.
Deploy
Review & deploy
The recipe pre-configures your tools, prompts, and resources. Review the setup, click Deploy. Your MCP server goes live at {slug}.chaincontext.dev. Managed hosting, zero infrastructure.
Safe by default. Write tools return unsigned calldata. Every call is pre-simulated (Tenderly + Blockaid), and high-risk actions pause for human approval.
Monetize & stream. Toggle x402 to charge per call in USDC, turn on streaming subscriptions, or publish to the MCP registry - all included.
Recipe will create
// Connect to ChainContext MCP server const mcp = createMCPClient({ url: 'https://usdc-tools.chaincontext.dev/mcp' }) // Read on-chain data const balance = await mcp.callTool('get_balance', { address: agent.wallet.address }) // Get unsigned calldata, agent signs locally const { rawTx } = await mcp.callTool('transfer', { to: recipient, amount: '100' })
Also works with
Connect
Connect your AI agent
Drop the endpoint URL into Claude Desktop, Cursor, or any MCP client. Wire it into your autonomous agent to read balances, react to on-chain events, get unsigned calldata, and sign transactions locally. No SDKs, no custom integration code.
Ecosystem
One MCP server,
every chain and protocol
Your ChainContext MCP server connects natively to any EVM chain, Solana, and the DeFi protocols built on them. Plug it into Claude, Cursor, Windsurf, or any MCP-compatible AI client.

Features
Everything you need to build and ship blockchain MCP servers
Visual block builder
Compose tool pipelines for any use case, from developer queries to autonomous agent transaction flows. Chain contract calls, transforms, unsigned tx builders, and response formatters without writing code.
MCP server recipes
Start from a recipe built for your use case: DeFi yield, liquidation monitoring, governance, trading, analytics, or security. Each recipe pre-configures tools, prompts, and resources. Customize further with 20+ individual templates.
Registry publishing
Publish your MCP server to the official MCP registry, ENS, on-chain registry on Base, or IPFS. Make it discoverable to AI agents and developer ecosystems across the web.
x402 monetization
Charge AI agents per tool call in USDC on Base or Solana. Sub-second settlement, sub-cent fees, no middleman. Agents sign an EIP-3009 transfer; payment settles on-chain before the tool runs.
Streaming subscriptions
Turn any chain event, new-block, or mempool feed into a live MCP Resource. Clients subscribe and receive notifications as events land. The first blockchain MCP builder with real eth_subscribe support.
Analytics & alerts
Monitor every call your agents make. Track tool usage, error rates, latency percentiles, and activity breakdown by agent. Set email or webhook alerts for quota thresholds and error spikes.
Non-custodial write tools
Write tools return unsigned transaction calldata. Agents sign with their own wallet. Private keys never touch ChainContext. Works with any EOA, smart account, or MPC wallet.
Human-in-the-loop approvals
Mark any write tool "requires approval" and pause execution until a human approves. Notifications land in your dashboard, email, or webhook. Pre-simulation via Tenderly + Blockaid shows the approver exactly what will happen.
Pre-execution safety
Every write tool call is simulated via Tenderly and scanned by Blockaid for malicious patterns before the unsigned tx reaches the agent. High-risk txs prompt the user to confirm via MCP elicitation.
On-chain server identity
Register your MCP server on-chain (ERC-8004 on Base) so AI clients can verify ownership cryptographically. Your wallet signs - your wallet is the identity. No platform lock-in, reputation accrues to you.
Resources & prompts
Expose on-chain data, ABIs, price feeds, and protocol documentation as MCP resources. Define reusable prompt templates with dynamic variable injection for your agents.
Use cases
What you can build with ChainContext
If it runs on a smart contract, your agents can read it, react to it, and execute on it. No custom integration required.
