Sensei MCP

Sensei MCP is a Model Context Protocol server that serves as an on‑chain development mentor for the Dojo framework and Cairo programming on Starknet. It addresses a common pain point for developers: navigating the steep learning curve of Cairo’s ownership model, memory layout, and type system while simultaneously mastering Dojo’s Entity‑Component‑System (ECS) architecture. By exposing a rich set of specialized tools—, , , , , and —Sensei transforms an AI assistant into a hands‑on tutor that can guide developers through every phase of a Dojo project, from initial scaffolding to production‑ready smart contracts.

The server’s value lies in its contextual expertise. Rather than providing generic documentation, Sensei offers targeted, step‑by‑step instructions that adapt to the developer’s current task. For example, when a user asks for help creating a model, the assistant automatically invokes the tool and delivers Cairo code snippets, best‑practice explanations, and memory‑layout recommendations that are specific to Dojo’s ECS patterns. This level of precision reduces trial‑and‑error and accelerates the learning curve for newcomers while allowing experienced developers to focus on higher‑level design decisions.

Key capabilities include:

• Tool‑centric guidance: Each tool encapsulates a distinct aspect of Dojo development, ensuring that advice is relevant and actionable.
• Incremental workflow support: Sensei encourages a disciplined build order—setup (), models (), logic (), configuration (), and testing ()—mirroring industry best practices for maintainable on‑chain applications.
• Seamless AI integration: The server plugs directly into Cursor IDEs and Claude Code, enabling agents to query Sensei automatically when contextually appropriate. This tight coupling eliminates friction between code writing and AI assistance.

In real‑world scenarios, Sensei MCP shines for teams building complex on‑chain worlds such as multiplayer games, decentralized simulations, or virtual economies. A developer can iteratively prototype a new entity type, test its interactions in isolation, and then integrate it into the broader world state—all with instant, AI‑generated guidance. The server’s focus on Cairo also makes it ideal for developers porting existing Solidity logic to Starknet, as it demystifies Cairo’s unique memory and ownership constraints.

Ultimately, Sensei MCP offers a personalized tutor experience for Dojo and Cairo development. By combining structured tooling, contextual AI assistance, and a clear incremental workflow, it empowers developers to write correct, efficient, and well‑tested smart contracts faster than they could rely on static documentation alone.
