Monad Mcp
Connects AI agents to the Monad blockchain for balance checks, token transfers, swaps, and DeFi operations across Uniswap, Kintsu/FastLane liquid staking, Morpho lending, and the Kuru CLOB. Transaction signing is handled by Privy embedded wallets, keeping private keys out of agent control. Ships with session key grants for auto-executing small transactions under preset limits, otherwise returns approval URLs for human review. Supports both mainnet and testnet, includes .nad name resolution, portfolio queries via DexScreener, and LiFi bridge quotes. Read operations work immediately via the hosted endpoint; write operations require Privy authentication. Useful when you need an LLM to execute on-chain actions with proper transaction custody boundaries.

Readme
monad-mcp
MCP server for the Monad blockchain. Your agent's gateway to balances, transfers, swaps, and DeFi on Monad — with signing handled by a Privy embedded wallet, never by the agent.
Built around a simple shape — stored requests + approval URLs + skill plugins — on Monad mainnet 143 / testnet 10143, with Privy as the wallet provider.
🌐 Landing page + live read-only demo: pareen.github.io/monad-mcp — query real Monad balances in your browser, exactly what the agent sees.
🔌 Connect it — no install, no terminal. In Claude Desktop or ChatGPT, add a custom connector and paste this URL:
https://monad-mcp.fly.dev/mcp
That's the whole setup — read tools (balances, prices, portfolios, token checks) work immediately. Step-by-step for each app: docs/connect-claude.md.
Prefer the terminal? One line in Claude Code:
claude mcp add --transport http monad https://monad-mcp.fly.dev/mcp # hosted
claude mcp add monad -- npx -y monad-mcp # or run it locally
