add_edges
Add multiple edges between nodes in a knowledge graph to define relationships, including edge types and optional weights, using the MemoryMesh MCP server.
Instructions
Add multiple new edges between nodes in the knowledge graph. Edges should be in active voice

Implementation Reference
- The switch case handler that executes the "add_edges" MCP tool logic by calling the knowledge graph manager to add edges and formatting the tool response.case "add_edges": const addedEdges = await this.knowledgeGraphManager.addEdges(args.edges); return formatToolResponse({ data: {edges: addedEdges}, actionTaken: "Added edges to knowledge graph" });
- The tool definition including name, description, and input schema for validating parameters to the "add_edges" tool.{ name: "add_edges", description: "Add multiple new edges between nodes in the knowledge graph. Edges should be in active voice", inputSchema: { type: "object", properties: { edges: { type: "array", description: "Array of edges to add", items: { type: "object", description: "Edge to add", properties: { from: {type: "string", description: "The name of the node where the edge starts"}, to: {type: "string", description: "The name of the node where the edge ends"}, edgeType: {type: "string", description: "The type of the edge"}, weight: { type: "number", description: "Optional edge weight (0-1 range). Defaults to 1 if not specified", minimum: 0, maximum: 1 } }, required: ["from", "to", "edgeType"], }, }, }, required: ["edges"], }, },
- src/integration/tools/registry/toolsRegistry.ts:43-45 (registration)Registers the static tools, including "add_edges", into the central tools registry map by name.allStaticTools.forEach(tool => { this.tools.set(tool.name, tool); });
- Core implementation of adding edges to the graph storage, with validation, events, and persistence. Called indirectly by the tool handler.async addEdges(edges: Edge[]): Promise<Edge[]> { try { this.emit('beforeAddEdges', {edges}); const graph = await this.storage.loadGraph(); // Validate edge uniqueness and node existence using GraphValidator const newEdges = edges.filter(edge => { GraphValidator.validateEdgeUniqueness(graph, edge); // Ensure weights are set return EdgeWeightUtils.ensureWeight(edge); }); if (newEdges.length === 0) { return []; } for (const edge of newEdges) { GraphValidator.validateNodeExists(graph, edge.from); GraphValidator.validateNodeExists(graph, edge.to); } graph.edges.push(...newEdges); await this.storage.saveGraph(graph); this.emit('afterAddEdges', {edges: newEdges}); return newEdges; } catch (error) { const errorMessage = error instanceof Error ? error.message : 'Unknown error occurred'; throw new Error(errorMessage); } }
