Tower-mcp is a niche technical implementation that bridges the Model Context Protocol (MCP) with the Tower ecosystem in Rust. While the architecture (using the Service trait) is technically sound and follows established Rust patterns, the project shows minimal market signal (4 stars, 2 forks) and zero recent velocity. Its defensibility is extremely low as it essentially maps the MCP spec onto the Tower middleware pattern—a task any senior Rust engineer could replicate in a few days. The primary risk is not from frontier labs (who are unlikely to care about specific Rust crate ecosystems) but from the official MCP SDKs or more established Rust networking projects (like those under the tokio-rs or tower-rs umbrellas) providing their own implementations. If MCP gains mass adoption, a more robust, official, or community-backed crate will likely supersede this personal experiment within 6 months. It serves more as a reference implementation or a 'starter' project than a defensible piece of infrastructure.
