Persistent Memory for GitHub Copilot
GitHub Copilot Agent Mode just got MCP support. ContextForge gives Copilot persistent memory via MCP — so it remembers your architecture, decisions, and debugging notes across every VS Code session.
Every Copilot chat starts blank
Copilot is great at autocomplete but useless for accumulated knowledge. The patterns your team agreed on last sprint? Gone. The bug pattern you keep hitting? Re-explained every time.
Copilot that remembers your project
With MCP + ContextForge, Copilot can save and search your project knowledge directly from VS Code. Architecture decisions, conventions, debugging insights — all available without re-explaining.
Setup in under 3 minutes
Get your API key
Sign up at contextforge.dev (free tier available) and copy your API key from the dashboard.
Add ContextForge to your project
Create .mcp.json in your project root:
{
"servers": {
"contextforge": {
"command": "npx",
"args": ["-y", "contextforge-mcp"],
"env": {
"CONTEXTFORGE_API_KEY": "your-api-key"
}
}
}
}Use Copilot Agent Mode
Open Copilot Chat in VS Code, switch to Agent Mode. ContextForge tools are now available.
What you can do
Native VS Code integration
No extra extension needed. ContextForge plugs into Copilot via the MCP standard that ships with VS Code.
Save from Copilot Chat
Tell Copilot in Agent Mode "remember the billing webhook needs base64 decoding" and it saves to your knowledge base.
Git-aware
Connect your GitHub repos and your commits/PRs sync to memory automatically. Copilot always knows what changed.
Works alongside other tools
Use Copilot for autocomplete, Claude Code for complex tasks. ContextForge is the shared memory across all of them.
Common questions
Does Copilot Agent Mode actually support MCP?
Yes — GitHub shipped MCP support for Copilot in VS Code in 2025. You can configure MCP servers in .mcp.json or VS Code settings.json. ContextForge works with the standard MCP configuration.
Do I need a Copilot subscription?
Yes, you need GitHub Copilot to use Agent Mode. ContextForge is the memory layer — it works with any Copilot subscription level that supports MCP.
Can I use this with Copilot in JetBrains IDEs?
Currently, MCP support in Copilot is for VS Code Agent Mode. As JetBrains adds MCP support to Copilot, ContextForge will work there too.
