Memory Bank MCP
Memory Bank MCP is an MCP server that provides AI coding assistants with remote read/write access to structured memory bank files, enabling persistent project-specific context across sessions for tools like Claude, Cline, Cursor, and Windsurf.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Agent memory/context persistence MCP. Local file-based storage. Memory may include sensitive agent context and PII. Protect storage directory. Encrypt sensitive memory entries.
⚡ Reliability
Best When
You use AI coding assistants like Cline or Cursor and want them to maintain consistent project context (what was done, decisions made, next steps) across multiple sessions and machines.
Avoid When
You need semantic search over memories (use a vector DB instead), or your memory needs extend beyond file-based text storage.
Use Cases
- • Maintaining persistent AI assistant context (architecture notes, decisions, progress) across coding sessions for multiple projects
- • Centralizing memory bank management so multiple AI tools can share the same project memory without file conflicts
- • Storing and retrieving structured documentation files that AI assistants reference to maintain coherent long-term project understanding
Not For
- • General-purpose key-value or vector database storage
- • Real-time collaborative document editing between human users
- • High-throughput data storage workloads beyond text-based memory files
Interface
Authentication
No authentication layer. Relies on filesystem-level access control via the MEMORY_BANK_ROOT environment variable. Project isolation is enforced by directory structure.
Pricing
MIT licensed. No cost. Smithery installation is also free.
Agent Metadata
Known Gotchas
- ⚠ MEMORY_BANK_ROOT must be set correctly; misconfiguration silently stores files in wrong location
- ⚠ No semantic search - agents must know file names to retrieve memories
- ⚠ Path traversal prevention means agents cannot access files outside the designated memory bank root
