V.E.L.O.C.I.T.Y. NMCP Server v1.0.0

Initial Release v1.0.0

Production-hardened, self-hosting Model Context Protocol (MCP) server in Rust with dynamic tool hosting.

Architecture

• Rust MCP server — High-performance protocol handling (stdio JSON-RPC + shared memory IPC)
• Dynamic tool hosting — Automatically discovers and hosts tools from the C# backend engine
• NDA binary format — 219x faster than JSON parsing (zero-allocation, zero-copy)

Features

• Dynamic Tool Discovery: Tools added to the C# engine are immediately available — no config, no restart
• Built-in NDA Tools: convert_to_nda, read_nda, execute_nda for binary format operations
• Dual Protocol: Stdio JSON-RPC v2.0 + Shared Memory IPC (64 KB mmap)
• 48 tests: 36 unit + 12 integration, all passing
• Zero warnings: cargo clippy, cargo doc clean
• Graceful shutdown: Ctrl+C handler with non-blocking stdio reader thread
• Process safety: Child process kill + reap on timeout
• IPC correctness: AtomicU8 Acquire/Release + SeqCst fences on length fields
• Input validation: Path traversal rejection, 1 MB max request, buffer overflow bounds
• Observability: Structured logging (tracing), health check endpoints
• Release profile: LTO, opt-level 3, codegen-units 1, panic=abort, stripped

Benchmark Results (Intel Core i5-14400F)

Operation	Mean Latency	Speedup vs JSON
JSON-RPC Parse	1,320 ns	baseline
Shared Memory R/W	115 ns	11.5x faster
Zero-Alloc Binary Parse	6.03 ns	219x faster

Binary

• Platform: Windows x64
• Size: 0.99 MB (self-contained, no runtime dependencies)
• Usage: velocity_mcp.exe --mode stdio or --mode shmem
