Reddit startup idea
Repo Context Cache Server
A self-hosted MCP-compatible service that continuously precomputes and serves a minimal, verifiable repository knowledge pack (architecture map, dependency paths, auth/payment flows, ownership, risk hotspots) optimized for LLM coding tools. It reduces repeated token spend by replacing exploratory file reads with deterministic, queryable repo context snapshots and change-aware diffs that LLMs can request on demand.

Repo Context Cache Server

Target customer
Engineering managers and platform/tooling leads at SMB-to-midmarket software companies (20–500 engineers) paying for Claude Code/Cursor/Windsurf usage and seeing rising token bills or context-window friction on mature codebases.
Problem-solution fit
The posts describe a consistent pattern: each new session burns tokens just to understand the repo, driving cost and limiting useful work. By serving precomputed, tool-callable context and only sending deltas after changes, teams cut input tokens and speed up time-to-first-useful-answer without sending code to third-party services.
