Your AI shouldn’t have to rediscover your codebase.
Every new prompt starts another round of searching, grepping, and reading. Harmony remembers, so your agent spends its time solving problems instead of rediscovering your codebase.

Built to eliminate Codebase Amnesia
From indexing and retrieval to formatting and token budgeting, every part of Harmony is engineered to reduce rediscovery and maximize useful context.
Hyper-Converged Contextual Indexing
Harmony unifies semantic search, symbol resolution, call graphs, imports, and recent code changes into a single memory index. Multiple ranking passes ensure every context bundle is complete, relevant, and compact.
Token Budgeting
Harmony intelligently packs the highest-value context into every request, eliminating unnecessary retrieval and keeping token usage predictable. More tokens go toward solving problems, not rediscovering your codebase.
Adaptive Context Expansion
When more context is needed, Harmony expands outward from the most relevant code: following callers, callees, symbols, and dependencies until the agent has exactly what it needs.
Built for LLMs, Not APIs
Most memory servers serialize context for machines. Harmony returns structured markdown designed for language models, improving comprehension while reducing wasted tokens.
Repository Isolation
Every repository is stored in its own isolated memory space with strict tenant separation. Harmony never mixes customer repositories, ensuring every agent only accesses the codebase it’s authorized to use.
Model-Aware Context
Claude Code, Cursor, Windsurf, Gemini, and future agents all consume context differently. Harmony automatically formats every context bundle for the model that’s asking.
Context that reasons, retrieves, and remembers.
Most MCP memory servers retrieve context. Harmony builds it. Hyper-Converged Contextual Indexing continuously understands your repository, expands only when needed, optimizes every request, and delivers context tailored for the coding agent using it.
Hyper-Converged Contextual Indexing
Harmony continuously builds a living understanding of your repository, connecting code, relationships, and recent changes into a single high-performance memory that’s always relevant, compact, and ready for every prompt.
Adaptive Context Expansion
Harmony starts with the smallest relevant context, then expands only when needed. Instead of searching your entire repository, it follows the most relevant paths until the agent has exactly what it needs.
Intelligent Token Budgeting
Harmony fills every request with the highest-value context that fits within your model’s token budget. Less wasted retrieval. More useful reasoning. More tokens spent writing code.
Agent-Aware Context
Every coding agent thinks differently. Harmony automatically formats every context bundle for Claude Code, Cursor, Windsurf, Gemini, and future agents, improving accuracy while reducing unnecessary tokens.
Most MCP memory retrieves. Harmony remembers.
Traditional MCP memory servers retrieve files. Harmony builds a living understanding of your repository, allowing coding agents to stop rediscovering code and start solving problems. Every prompt begins with the right context instead of another round of searching.
| Traditional MCP Memory | Harmony |
|---|---|
| Retrieves relevant files | Understands the repository |
| One retrieval pass | Multi-stage context construction |
| Static context | Adaptive context expansion |
| Generic output | Agent-aware context bundles |
| Repeats discovery every session | Persistent repository memory |
| Token-heavy retrieval | Token-budgeted reasoning |
Traditional memory servers help agents find information.
Harmony helps agents remember it.
The result is fewer searches, lower token costs, faster responses, and more accurate code generation.
The first benchmark built for AI coding agents.
Most benchmarks measure language models. CAB (Codebase Amnesia Benchmark) measures something different: how efficiently coding agents understand, retrieve, and reuse knowledge inside real software projects. Compare any coding agent before and after Harmony using the same repository, the same prompts, and the same tasks.
Same coding agent. Same repository. Same prompts. The only difference is Harmony.

Harmony compressed what would have been months of context-setup work into a single afternoon. Our Claude Code sessions now start with full repo awareness from the first prompt. No warm-up, no repeated file reads. The token savings alone paid for the switch.
We built our entire AI coding workflow on MCP-connected agents. Harmony was the missing piece. It gave our agents the codebase memory they needed to stop re-discovering the same modules on every task. Landmark Expansion is a game-changer for our monorepo.
Token waste was quietly eating our Claude API budget. After installing Harmony, Cursor sessions are dramatically faster and we have seen a measurable drop in redundant API calls. The XML + Markdown format makes a real difference. Our agent actually understands the context it receives.
