Implementation Reference
- Core handler function that executes the tool logic: extracts factId, deletes the fact via factStore.deleteFact, and returns success or error response.async handleDeleteFact(args) { try { const { factId } = args; await this.factStore.deleteFact(factId); return { content: [ { type: 'text', text: `✅ Fact ${factId} deleted successfully.`, }, ], }; } catch (error) { return { content: [ { type: 'text', text: `Error deleting fact: ${error.message}`, }, ], isError: true, }; } }
- src/tools/modules/MemoryOperations.js:90-106 (registration)Registers the memory_delete_fact tool with the MCP server, including description, input schema, and reference to the handler function.server.registerTool( 'memory_delete_fact', 'Delete a fact from the memory system', { type: 'object', properties: { factId: { type: 'string', description: 'The ID of the fact to delete', }, }, required: ['factId'], }, async (args) => { return await this.handleDeleteFact(args); } );
- JSON schema defining the input parameters for the tool: requires a 'factId' string.{ type: 'object', properties: { factId: { type: 'string', description: 'The ID of the fact to delete', }, }, required: ['factId'], },
- src/tools/MemoryTools.js:23-29 (registration)Higher-level registration entry point that calls registerTools on MemoryOperations (which registers memory_delete_fact).async registerTools(server) { // Register tools from modular components this.operations.registerTools(server); this.queryHandler.registerTools(server); this.streamingTools.registerTools(server); this.management.registerTools(server); }
- src/tools/MemoryTools.js:14-15 (helper)Instantiates the MemoryOperations class with factStore and qualityScorer dependencies.this.operations = new MemoryOperations(factStore, qualityScorer); this.queryHandler = new MemoryQueryHandler(factStore, processor);
