Yul GasMaster
Connect an agent to an EVM gas-optimization MCP that refactors Solidity toward efficient Yul when you are tuning on-chain costs before mainnet deploy.
Overview
Yul-GasMaster is an MCP server for the Build phase that helps optimize EVM gas by refactoring Solidity toward efficient Yul through agent-callable tools.
What is this MCP server?
- Yul-GasMaster MCP focused on EVM gas optimization via Yul-oriented refactoring
- Targets Solidity code paths agents can submit for efficiency review through MCP tools
- Hosted remote SSE endpoint on Vercel—no local compiler farm required to start
- Premium tier gated by EIP-3009 payment-signature on the remote connection
- Manifest version 1.0.0 under io.github.Evozim/yul-gasmaster
- Server version 1.0.0 in published MCP schema
- 1 remote SSE transport (yul-gasmaster-mcp.vercel.app)
- 1 secret header field documented for premium payment (EIP-3009)
What problem does it solve?
On-chain gas eats margin and user experience, but solo builders lack time to hand-tune Solidity and Yul across every hot path.
Who is it for?
Indie Web3 builders optimizing contracts pre-mainnet with agent-assisted Yul refactoring guidance.
Skip if: Non-EVM projects, teams wanting guaranteed audit-grade correctness without local testing, or beginners with no Solidity context.
What do I get? / Deliverables
After registering the MCP server, your agent can propose Yul-oriented gas optimizations you can benchmark before you ship contract upgrades.
- Agent-mediated gas optimization and Yul-oriented refactoring recommendations
- Repeatable MCP hook for contract tuning sessions
- Clear remote endpoint config for CI or local agent workflows

Common Questions / FAQ
Who is Yul GasMaster for?
Developers shipping EVM contracts who use MCP-enabled agents and want gas-focused refactoring suggestions grounded in Yul efficiency patterns.
When should I use Yul GasMaster?
Use it during build when profiling shows expensive paths, before redeploying to testnet or mainnet, and while iterating with an agent on contract changes.
How do I add Yul GasMaster to my agent?
Configure the remote SSE MCP entry (https://yul-gasmaster-mcp.vercel.app/api/mcp) in your agent’s MCP settings and add the payment-signature header when premium EIP-3009 access is required.
