Give Your AI Coding Agent a Memory That Survives Every Session

Open a new session with Claude Code, Cursor, or Copilot and it has no idea what you were doing yesterday. Your stack, your decisions, the bug you spent an hour explaining — gone. So you re-explain. Again.

The root cause is simple: your AI's memory only lasts one conversation. Close the terminal and it's wiped.

ContextForge fixes that. It's an MCP server that gives any AI agent a permanent, searchable memory that carries across every session and every project. Below is the full setup — it takes three commands.

The walkthrough uses Claude Code as the example, but the same setup works for Cursor, ChatGPT, Claude Desktop, Windsurf, and GitHub Copilot.

The setup, in three commands

1. Install the MCP server

npm install -g contextforge-mcp

2. Connect it to your editor — the wizard asks for your API key (grab a free one at contextforge.dev):

npx contextforge-setup

3. Initialize your project — this is the step people skip:

npx contextforge-mcp init

That last command writes a small rules file (CLAUDE.md for Claude Code, .cursorrules for Cursor) that tells your AI to use ContextForge for memory. Without it, your agent silently falls back to its built-in memory and ignores ContextForge — even though the server is connected.

The payoff

Once it's connected, you just talk to your agent like normal:

"Remember this is a todo app with Next.js and Supabase, deployed on Vercel. Save it to memory."

It stores that as a real, searchable memory — not in the chat, in a permanent store. Plant a couple of tasks the same way, then close the terminal and open a brand-new session:

"Let's start working on this project. What do I have pending?"

And it knows. New session, clean slate, and your agent already has your stack, your context, and your open tasks — no re-explaining. You can browse everything in the dashboard, organized by project.
