create_entities

• Create multiple new entities in the knowledge graph
• Input: entities (array of objects)
  • Each object contains:
    • name (string): Entity identifier
    • entityType (string): Type classification
    • observations (string[]): Associated observations
• Ignores entities with existing names

create_relations

• Create multiple new relations between entities
• Input: relations (array of objects)
  • Each object contains:
    • from (string): Source entity name
    • to (string): Target entity name
    • relationType (string): Relationship type in active voice
• Skips duplicate relations

add_observations

• Add new observations to existing entities
• Input: observations (array of objects)
  • Each object contains:
    • entityName (string): Target entity
    • contents (string[]): New observations to add
• Returns added observations per entity
• Fails if entity doesn't exist

delete_entities

• Remove entities and their relations
• Input: entityNames (string[])
• Cascading deletion of associated relations
• Silent operation if entity doesn't exist

delete_observations

• Remove specific observations from entities
• Input: deletions (array of objects)
  • Each object contains:
    • entityName (string): Target entity

delete_relations

• Remove specific relations from the graph
• Input: relations (array of objects)
  • Each object contains:
    • from (string): Source entity name
    • to (string): Target entity name
    • relationType (string): Relationship type
• Silent operation if relation doesn't exist

read_graph

• Read the entire knowledge graph
• No input required
• Returns complete graph structure with all entities and relations

search_nodes

• Search for nodes based on query
• Input: query (string)
• Searches across:
  • Entity names
  • Entity types
  • Observation content
• Returns matching entities and their relations

open_nodes

• Retrieve specific nodes by name
• Input: names (string[])
• Returns:
  • Requested entities
  • Relations between requested entities
