MCP Interactive Systems Workbench & Visual Reference Suite

STAGE 00 • ARCHITECTURAL PROGRESSION & CODE MODULARITY

Systematic Breakdown — Master MCP Architecture

Model Context Protocol is the open standard that connects AI models to external tools, databases, and local systems. Partition complexity across three layers: 1) A 4-phase engineering roadmap, 2) A strictly modular directory layout, and 3) Isolated protocol boundaries.

STAGE 11 • CRYPTOGRAPHY & SMART CONTRACT SUITE

EVM Calldata, Safe Multisig & Slither Static Analysis

Autonomous on-chain agent infrastructure. Model Context Protocol serves as a deterministic airgap: models construct verified calldata while isolated co-signers and simulations prevent wallet drain.

Core Architectural Rule: Why MCP is Essential for Cryptography & Smart Contracts

The Threat: Stochastic AI Models Must Never Possess Private Keys

If an autonomous LLM is given access to raw private keys or raw transaction signing RPCs, an indirect prompt injection attack can irreversibly drain account balances in one transaction. MCP provides an airgapped, 3-stage validation boundary:

1. Zero Key Access

The host LLM constructs only intent arguments. The MCP server serializes these into raw hexadecimal ABI calldata without touching keys.

2. Pre-Execution Simulation

Before broadcasting, the calldata is simulated against an archival node using eth_call with state overrides to verify token delta accuracy.

3. Multi-Sig & Session Keys

Execution is passed to a Gnosis Safe 2-of-2 multisig or an ERC-4337 smart account session key with strict daily spending allowances.
