aim_memory_store
Store and organize persistent memories about people, projects, and concepts with custom categories. Create separate knowledge graphs for different contexts like work or personal.
Instructions
Store new memories. Use this to remember people, projects, concepts, or any information worth persisting.
AIM (AI Memory) provides persistent memory for AI assistants. The 'aim_memory_' prefix groups all memory tools together.
WHAT'S STORED: Memories have a name, type (person/project/concept/etc.), and observations (facts about them).
DATABASES: Use the 'context' parameter to organize memories into separate graphs:
Leave blank: Uses the master database (default for general information)
Any name: Creates/uses a named database ('work', 'personal', 'health', 'research', etc.)
New databases are created automatically - no setup required
IMPORTANT: Use consistent, simple names - prefer 'work' over 'work-stuff'
STORAGE LOCATIONS: Files are stored as JSONL (e.g., memory.jsonl, memory-work.jsonl):
Project-local: .aim directory in project root (auto-detected if exists)
Global: User's configured --memory-path directory
Use 'location' parameter to override: 'project' or 'global'
RETURNS: Array of created entities.
EXAMPLES:
Master database (default): aim_memory_store({entities: [{name: "John", entityType: "person", observations: ["Met at conference"]}]})
Work database: aim_memory_store({context: "work", entities: [{name: "Q4_Project", entityType: "project", observations: ["Due December 2024"]}]})
Master database in global location: aim_memory_store({location: "global", entities: [{name: "John", entityType: "person", observations: ["Met at conference"]}]})
Work database in project location: aim_memory_store({context: "work", location: "project", entities: [{name: "Q4_Project", entityType: "project", observations: ["Due December 2024"]}]})
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| context | No | Optional memory context. Defaults to master database if not specified. Use any descriptive name ('work', 'personal', 'health', 'basket-weaving', etc.) - new contexts created automatically. | |
| location | No | Optional storage location override. 'project' forces project-local .aim directory, 'global' forces global directory. If not specified, uses automatic detection. | |
| entities | Yes |
