Before you install MCP Knowledge Graph

AgenticMart scanned MCP Knowledge Graph on Nov 5, 2026 with automated checks for hidden code, known-malicious packages, leaked secrets and vulnerable dependencies. The result covers one commit under our scan policy, so review what access you give it and check any advisories shown here.

What it can access

An MCP server is a program your AI app starts and talks to. A local one runs with your user's permissions: it can see the files, environment variables and network your account can.

Before you install

Pin the version you reviewed instead of always installing the latest release.
Read the tool list or scripts before the first run, and keep approval prompts on for actions that write, send or delete.

aim_memory_link
Link two memories together with a relationship. Use this to connect related information. RELATION STRUCTURE: Each link has 'from' (subject), 'relationType' (verb), and 'to' (object). - Use active voice verbs: "manages", "works_at", "knows", "attended", "created" - Read as: "from relationType to" (e
aim_memory_add_facts
Add new facts to an existing memory. Use this to append information to something already stored. IMPORTANT: Memory must already exist - use aim_memory_store first. Throws error if not found. RETURNS: Array of {entityName, addedObservations} showing what was added (duplicates are ignored). DATABAS
aim_memory_forget
Forget memories. Removes memories and their associated links. DATABASE SELECTION: Entities are deleted from the specified database's knowledge graph. LOCATION OVERRIDE: Use the 'location' parameter to force deletion from 'project' (.aim directory) or 'global' (configured directory). Leave blank fo
aim_memory_remove_facts
Remove specific facts from a memory. Keeps the memory but removes selected observations. DATABASE SELECTION: Observations are deleted from entities within the specified database's knowledge graph. LOCATION OVERRIDE: Use the 'location' parameter to force deletion from 'project' (.aim directory) or
aim_memory_unlink
Remove links between memories. Keeps the memories but removes their connections. DATABASE SELECTION: Relations are deleted from the specified database's knowledge graph. LOCATION OVERRIDE: Use the 'location' parameter to force deletion from 'project' (.aim directory) or 'global' (configured direct
aim_memory_read_all
Read all memories in a database. Returns every stored memory and their links. FORMAT OPTIONS: - "json" (default): Structured JSON for programmatic use - "pretty": Human-readable text format DATABASE: Reads from the specified 'context' database, or master database if not specified. EXAMPLES: - aim
aim_memory_search
Search memories by keyword. Use this when you don't know the exact name of what you're looking for. WHAT IT SEARCHES: Matches query (case-insensitive) against: - Memory names (e.g., "John" matches "John_Smith") - Memory types (e.g., "person" matches all person memories) - Facts/observations (e.g.,
aim_memory_get
Retrieve specific memories by exact name. Use this when you know exactly what you're looking for. VS aim_memory_search: Use aim_memory_get for exact name lookup. Use aim_memory_search for fuzzy matching or when you don't know exact names. RETURNS: Requested entities and relations between them. Non
aim_memory_list_stores
List all available memory databases and show current storage location. DATABASE TYPES: - "default": The master database (memory.jsonl) - used when no context is specified - Named databases: Created via context parameter (e.g., "work" -> memory-work.jsonl) RETURNS: {project_databases: [...], global
