Roo Code Memory Bank MCP Server
MCP server providing persistent memory bank functionality for Roo Code (and other AI coding assistants) — storing and retrieving project-specific context including architecture decisions, code patterns, progress notes, and development guidelines across sessions. Enables AI coding agents to maintain project awareness between context resets without re-reading all project files.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Local file storage. No network calls. No credentials. Consider .gitignore for sensitive project context or commit to git for team sharing.
⚡ Reliability
Best When
A developer using Roo Code or other AI coding assistants needs persistent project context — the memory bank stores what the AI needs to know between sessions without hitting context limits.
Avoid When
You're doing one-off coding tasks without ongoing project context — the overhead of maintaining a memory bank isn't worth it for simple tasks.
Use Cases
- • Persisting project architecture and coding conventions across Roo Code sessions from development agents
- • Storing progress notes and decision rationale from coding session agents
- • Maintaining project-specific rules and guidelines for AI coding assistants from config agents
- • Retrieving relevant project context at session start from onboarding agents
- • Tracking implementation progress across multiple coding sessions from project tracking agents
- • Sharing project context between different AI coding tools from integration agents
Not For
- • Long-term knowledge management beyond project context (use knowledge base tools)
- • Teams not using Roo Code, Cline, or similar AI coding assistants
- • Replacing proper project documentation (complements, not replaces, docs)
Interface
Authentication
No authentication — local file-based memory bank. No external service required. Memory stored in local files.
Pricing
Free open source memory bank MCP. No external service costs.
Agent Metadata
Known Gotchas
- ⚠ Memory bank requires active maintenance — outdated entries can mislead the AI assistant
- ⚠ Memory structure conventions should align with Roo Code's expected format for best results
- ⚠ File-based storage means memory bank can be inspected/edited manually — useful for debugging
- ⚠ Large memory banks can slow context loading — keep entries concise and relevant
- ⚠ Community MCP targeting Roo Code users — may not work optimally with other AI coding tools
- ⚠ Memory bank context is consumed as tokens — be selective about what to store
