Persistent Memory for AI Coding Agents
Stop your AI coding agent from forgetting your project every session. ContextForge gives Claude Code, Cursor, and Copilot persistent memory via MCP — semantic search, Git integration, free tier.
Your coding agent has amnesia
Every session, the agent forgets your architecture, your naming conventions, last week's debugging insight. You explain. Again. The context window fills with redundant catch-up before any real work happens.
Memory that survives every session
ContextForge gives your coding agent a persistent memory it can query like search. Project decisions, architecture notes, Git history — all retrievable across sessions, projects, and team members.
Setup in under 3 minutes
Sign up at contextforge.dev
Free tier includes 200 documents, 500 queries/month, and 1 project. No credit card required.
Install the MCP server
One command, any MCP-compatible coding agent:
npx contextforge-mcpConnect your coding agent
Add the ContextForge MCP server to Claude Code, Cursor, or Copilot. Setup details for each tool live on the tool-specific pages.
What you can do
Project-scoped memory
Organize knowledge by project. Your auth decisions stay separate from your billing notes. The agent retrieves only what is relevant to the current codebase.
Semantic search
Vector embeddings power retrieval. "How do we handle payments?" finds your "Invoice Workflow" document because the meanings match — not just the keywords.
Git commit and PR sync
Wire ContextForge to your repo. Every commit and PR becomes searchable context — the agent knows what shipped, who touched what, and why.
One server, every agent
Built on the open MCP standard by Anthropic. Install once, query from Claude Code, Cursor, Copilot, ChatGPT, and Windsurf.
Team-shared memory
Invite collaborators to projects. Your team's knowledge is the agent's knowledge. No more onboarding-by-Slack-archaeology.
Works with every major coding agent
Real-world use cases
Multi-session refactor
Pick up where you left off three days ago. The agent remembers the decisions you made about file structure, the patterns you chose, and the dead ends you already ruled out.
Code review handoff
Reviewer and author share the same memory. Comments, conventions, and prior decisions are first-class context — not lost in PR threads.
Long-running tasks across context windows
Even when the conversation window resets, the project memory persists. The agent re-queries what it needs instead of starting from zero.
Cross-repo platform work
Working across services? ContextForge keeps a separate memory per project so the agent does not confuse your billing repo conventions with your frontend repo conventions.
Common questions
What is an AI coding agent?
An AI coding agent is an autonomous AI tool that helps developers write, refactor, and debug code by performing multi-step tasks across files. Examples include Claude Code, Cursor (especially Agent Mode), GitHub Copilot Agent Mode, and Windsurf. They differ from traditional autocomplete by reasoning about your codebase as a whole instead of producing a single-shot suggestion.
Do AI coding agents have memory between sessions?
No. By default, Claude Code, Cursor, Copilot, and similar agents start every session with no memory of previous conversations, project decisions, or debugging insights. You re-explain your architecture every time. ContextForge solves this via the open MCP standard, giving your agent a persistent semantic memory that lasts across sessions.
How does ContextForge differ from Mem0 or Zep for coding agents?
ContextForge is purpose-built for coding workflows: Git commit and PR integration, project-based organization that matches how developers think, semantic search tuned for technical content, and native MCP support across Claude Code, Cursor, Copilot, ChatGPT, and Windsurf. Mem0 and Zep target general-purpose AI agents (chatbots, assistants); ContextForge targets coding agents specifically.
Does this work with Claude Code, Cursor, AND Copilot?
Yes. Because ContextForge speaks the open MCP (Model Context Protocol) standard, one memory server works across every major coding agent. Setup is identical: install via npx, paste your API key, done. See the tool-specific pages for per-agent instructions.
Is there a free tier?
Yes — free forever. The free tier includes 1 project, 3 spaces, 200 documents, and 500 queries per month. No credit card required. Pro starts at $9/month with 25 projects, Git integration, and team collaboration.
