How to Give Cline Persistent Memory with MCP
Cline is a powerful agentic coding assistant for VS Code — but like every AI tool, it forgets everything between sessions. This guide shows you how to give Cline permanent memory in 30 seconds using cachly's MCP server.
The problem: Cline starts cold every session
Cline is great at executing multi-step tasks autonomously — but it has no memory between sessions. Every time you open VS Code, Cline starts with zero context:
- ✗Doesn't know your tech stack or architectural decisions
- ✗Can't recall bugs it helped you fix last week
- ✗Unaware of team conventions it learned in previous sessions
- ✗No knowledge of which approaches you tried and abandoned
- ✗Can't learn from past mistakes across runs
For an agentic tool like Cline, this is especially painful — it re-explores the same codebase structure, re-discovers the same patterns, and sometimes repeats the same mistakes.
The solution: cachly MCP server
cachly is an MCP (Model Context Protocol) server that gives Cline a persistent AI Brain. 89 memory tools that survive across sessions, across editors, across your entire team.
smart_recallAuto-surfaces relevant context at the start of every Cline session
learn_from_attemptsRecords what worked and what failed — so Cline doesn't repeat mistakes
causal_traceTraces any bug through your full git history in one call
brain_predictWarns Cline about failure patterns before it executes risky changes
brain_from_gitPre-loads your entire git history before Cline's first run
team_broadcastShares discoveries across your whole team's AI assistants
Setup: one command
npx @cachly-dev/mcp-server@latest setupThe wizard detects VS Code (where Cline runs) and writes the MCP config automatically. For Cline, the config goes into your VS Code settings or Cline's MCP configuration:
// VS Code settings / Cline MCP config (auto-written by cachly setup)
{
"mcpServers": {
"cachly": {
"command": "npx",
"args": ["-y", "@cachly-dev/mcp-server@latest"],
"env": {
"CACHLY_JWT": "your-token-here"
}
}

Why cachly is especially powerful for Cline
Cline runs autonomously across many steps — which makes persistent memory even more valuable:
learn_from_attempts across agent runs
When Cline tries an approach and it fails, cachly records that failure. The next time Cline runs — even days later — it already knows what not to do. No more repeating the same mistakes.
brain_predict before risky operations
Before Cline executes a destructive change, brain_predict checks it against past incidents. If a similar change caused a problem before, Cline gets warned automatically.
brain_from_git loads codebase history
On first setup, brain_from_git reads your entire git log and extracts lessons — bugs fixed, patterns chosen, decisions made. Cline arrives at every task already knowing your codebase history.
What a Cline session looks like with cachly
# Cline starts a new task: "refactor the payment service"
#
# cachly smart_recall fires automatically:
> Context loaded: payment service
>
> Previous sessions:
> - Stripe webhook handler refactored (2026-04-18)
> - idempotency_key required on all charge calls (2026-04-18)
> - Webhook signature validation must happen before JSON parse
>
> brain_predict: ⚠️ Medium risk
> Similar refactor in 2025-09 caused a race condition
> in the retry queue. Recommend adding integration test.
