Server Details

Shared cross-LLM long-term memory over MCP: semantic recall, sessions, and media (pgvector).

Glama couldn't complete the latest health check. If this server requires authentication, missing or expired test credentials may be the cause. A test profile lets Glama authenticate for health checks and discover tools; it is separate from your personal connections.

If you are the author, claim ownership, then add or update a test profile under Admin → Test Profile.

TDQS

A4.1/5.0

Scored across 12 tools

Disambiguation5/5

Each tool maps cleanly to one operation: remembering/searching/listing/updating/deleting memories, the media upload lifecycle, or session save/load. The conceptually close pairs like recall/list_memories and remember/save_session are clearly distinguished by purpose and result shape.

Naming Consistency4/5

Most tools follow a verb_noun pattern such as create_upload, get_memory, list_memories, and save_session. A few single-word verbs like remember, recall, forget, ping, and update break the pattern, but the naming remains readable and not chaotic.

Tool Count5/5

Twelve tools cover memory, media, and session workflows without redundancy, and each tool earns its place in the lifecycle. This is well within the ideal scope for a server of this purpose.

Completeness4/5

Memory CRUD is well covered with remember, get_memory, list_memories, recall, update, and forget, and media uploads have create, confirm, and download support. Session support is thinner—only save and load—so explicit session listing or deletion would need to be inferred through memory ids, which is a minor gap.
