Frontier reasoning for coding agents who'd rather ship than meander.
ReasonOS is a closed-source Remote MCP Server running over SSE. It provides Gemini, Cursor, Windsurf, and Claude Code with the missing cognitive disciplines: Argon 1.00 tri-path search, Munger failure inversion, AST context compression, and sub-second execution velocity.

Add to your Cursor (.cursor/mcp.json) or Claude Desktop config:
Four architectural surfaces. Zero speculative bloat.
Engineered to eliminate conversational latency and force lightweight models into senior engineer execution.
Stop paying for conversational filler.
Standard models waste 15 seconds outputting polite preambles ("Certainly! I'd be happy to...") and rewriting 400 lines of unchanged code. Velocity Mode injects zero-preamble and surgical delta-only invariants, cutting response latency from 15s to 0.8s.
After: 22 tokens (0.8s) Target / Replacement delta diff emitted at token #0.
60–80% Context Pruning.
Pasting 2,000-line files into Gemini or Claude slows prefill to a crawl. The compress_context tool extracts pure typed signatures (class, def, interface), dropping model Time-To-First-Token by 3x.
Argon 1.00 & GPT-6.1 Terra Tri-Path Reasoning.
Simulates Path α (Direct Greedy), Path β (Asynchronous Optimal), and Path γ (Fault-Tolerant) with Munger Inversion Radar before any code is generated.
Executive Bento Decks.
Synthesizes publication-grade 16:9 widescreen PowerPoint decks (.pptx) and auto-formula Excel models (.xlsx).
What ReasonOS is. What it firmly isn't.
Most coding tools are thin prompt wrappers that leak your secrets or add 20 seconds of discursive chat. We built an isolated cloud execution engine.
Client-side prompt dumps that leak intellectual property and allow prompt injection.
Isolated proprietary container on Railway. Customers only hold an encrypted SSE URL.
Meandering preambles ("Let me think about how to approach this...") that drain tokens.
Zero preamble. Starts token #0 with the exact verified tool call or surgical unified diff.
Rewriting 500 lines to change 3 lines, introducing accidental syntax regressions.
Minimal drop-in boundary replacements verified against strict type contracts.
Predictable developer pricing.
