One Profile, Every AI Tool: Using MemoryCode Across Claude, Cursor, and Windsurf
Most people who work seriously with AI don't use just one tool. Claude Desktop for research and writing. Cursor for code. Windsurf for a different part of the workflow. And maybe Claude.ai or ChatGPT when you're on a different machine or need a quick session.
The friction this creates is usually invisible until you notice it: you've explained your background, preferences, and working style to each tool separately, at different levels of detail, and they've each drifted in different directions.
MemoryCode is designed to solve this across every tool you use.
The Multi-Tool Context Problem
When you start a new session in any AI tool, the model has no memory of previous conversations. This is by design — privacy and isolation are the default. But it means that every tool you use maintains a separate, disconnected understanding of who you are.
A few patterns emerge:
Tool-by-tool configuration drift. You might have detailed custom instructions in Cursor, a shorter profile in Claude Desktop, and nothing configured in Windsurf. Over time, these diverge further.
The context tax on every switch. Moving from Cursor to Claude Desktop to handle a question outside the IDE means re-establishing context — either by pasting a system prompt, relying on the model's default behavior, or just accepting lower-quality output.
Chip switching without portability. If you've figured out that a "structured output" mode works better for reports and a "creative divergence" mode works for ideation, that knowledge is locked in your head — not in a format that travels across tools.
How MemoryCode Addresses This
MemoryCode separates your context into two layers that both travel with you:
Identity — your professional profile, background, skills, and goals. You configure this once. It doesn't change based on which tool you're using or what task you're working on.
Cognitive Chip — the behavioral layer: how you want the AI to reason and respond. You pick the chip that fits the current task. The same chips are available regardless of which AI tool you're using.
Both layers can be delivered to any AI tool using one of two methods.
Connecting MemoryCode to Multiple Tools
Claude Desktop
Claude Desktop supports MCP natively. Once you configure @memorycode/mcp-server in Claude Desktop's config file, your identity and active chip load automatically at session start.
Cursor
Cursor supports MCP servers in its agent mode. The MemoryCode server connects the same way as in Claude Desktop — a one-time config edit, then automatic loading.
Windsurf
Windsurf's Cascade agent supports MCP. Adding the MemoryCode server gives Cascade access to your identity and active chip.
LM Studio
LM Studio supports MCP for local models. If you're running models locally and want the same profile available there, the setup process is the same as other MCP clients.
Claude.ai, ChatGPT, Gemini, and Other Web Tools
Web-based tools don't support MCP, but QuickCopy handles them. Generate your context block in MemoryCode and paste it into Claude.ai's "Set a system prompt" field, ChatGPT's Custom Instructions, or the opening message of any session.
The same identity + chip combination you use with your MCP-connected tools is available as a copy-paste block for everything else. See QuickCopy vs MCP: Which to Use for a fuller comparison.
A Practical Multi-Tool Setup
Here's what a typical multi-tool configuration looks like:
Daily tools (MCP)
Claude Desktop, Cursor, and Windsurf each have @memorycode/mcp-server configured. Your identity and active chip load at session start without any manual step.
Occasional tools (QuickCopy)
When you use Claude.ai or ChatGPT — maybe on a different machine, or for a quick task — you hit Copy in MemoryCode and paste. Ten seconds, consistent context.
Chip switching
When you move from writing to code review, you switch chips in MemoryCode. The new chip takes effect in the next session of any MCP-connected tool, and the next time you generate a QuickCopy block.
The identity layer — your background, role, goals — never changes. Only the behavioral layer switches.
How to Think About Which Chip to Use Across Different Tools
The answer depends on the task, not the tool. A few patterns that work well across different workflows:
Cursor + Code Review chip: When reviewing your own work or asking Cursor to evaluate architectural decisions, a chip that checks assumptions and lists tradeoffs produces more useful feedback than a general-purpose response.
Claude Desktop + Structured Output chip: Research, summarization, and document drafting benefit from a chip that leads with conclusions and structures output clearly. Long, discursive answers are harder to work with.
Any tool + Async Communication chip: When drafting Slack messages, status updates, or email, a chip tuned for scannable written output eliminates the filler that AI tends to add unprompted.
Brainstorming sessions + Creative Divergence chip: Switching to a chip that prioritizes breadth before judgment is useful for any session where you want range — regardless of which tool you're in.
The point isn't that Cursor requires one chip and Claude requires another. It's that the task type drives the chip selection, and you can make that switch cleanly because your identity stays stable underneath.
What Stays in Sync and What Doesn't
What syncs automatically:
- Your identity profile (via MCP or the next QuickCopy you generate)
- Your chip selection (active chip is always what's currently set in MemoryCode)
- Any chip you've customized
What doesn't sync:
- Conversation history — AI tools don't share this, and MemoryCode doesn't change that
- Tool-specific settings (model version, temperature, tool permissions) — those stay in each app
MemoryCode doesn't connect to any external server or sync data across devices by default. Your profile lives in your browser's local storage. If you want the same setup on a different machine, export your profile from one and import it on the other.
Getting Started
- Open MemoryCode and configure your identity — takes a few minutes the first time.
- Pick a cognitive chip or start with the default.
- For MCP-compatible tools, follow the relevant guide: Claude Desktop, Cursor, Windsurf, LM Studio, OpenClaw. Or use the full MCP manual.
- For web tools, use QuickCopy.
No account required. All data stays local.
