memorious-mcp
memorious-mcp is a local Model Context Protocol (MCP) server that provides semantic long-term memory operations—store, recall (vector similarity search), and forget—using ChromaDB for persistent on-disk storage.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
The README claims local-only processing and warns that data is stored unencrypted on disk in the .memorious directory. No authentication/authorization model is described, so anyone with local access could read the stored memories. Memory/backups management should be treated as a security control.
⚡ Reliability
Best When
You want local-only semantic memory for an MCP-capable assistant, with persistent storage and simple store/recall/forget tool semantics.
Avoid When
You need encryption-at-rest, multi-tenant isolation, or authentication/authorization controls beyond local usage.
Use Cases
- • Personal assistant memory (remember preferences and facts across sessions)
- • Project-/folder-scoped knowledge management for AI agents
- • Context preservation for local developer workflows
- • Semantic retrieval when queries don’t exactly match stored keys
Not For
- • Storing highly sensitive data that would be unsafe unencrypted on disk
- • Environments needing centralized/networked memory services or managed hosting
- • Use cases requiring fine-grained access control across users
Interface
Authentication
No authentication/authorization is described. The intended usage is local stdio MCP transport, so access control is effectively limited to local machine access.
Pricing
Open-source / local execution; no hosted pricing mentioned.
Agent Metadata
Known Gotchas
- ⚠ Data is persisted to an unencrypted on-disk directory (.memorious by default), so agents should avoid storing secrets.
- ⚠ No auth is described; assume the MCP server is not safe for multi-user/shared environments.
- ⚠ Store/recall/forget are keyed around short canonical keys; poor key design can reduce recall quality.
