Could you build this?
Partial A local macOS app integrating MCP and Solana RPC calls is feasible, but developing secure enclave-based transaction signing policies and non-bypassable guardrails requires specialized cryptographic and blockchain security expertise.
What it would actually take: The architecture involves a Swift macOS app connecting via Model Context Protocol (MCP) to an LLM, paired with local secure key storage (Apple Keychain/Secure Enclave) and Solana SDKs. The critical hard part is building a secure, verifiable transaction policy engine that parses low-level Solana instruction data (USDC SPL-token transfers) and enforces strict spending bounds before signing. This requires deep domain knowledge of Solana transaction serialization and local client security.
