Implementation Reference

• src/services/memory/entries.js:295-312 (handler)

  The implementation of the deleteEntry function which removes an entry, its revisions, and associated relations from the database.

  export async function deleteEntry(store, id) {
    await store.init();
    const existing = await getEntry(store, id);
    if (!existing) return { deleted: false, id };
  
    await store.adapter.exec('BEGIN');
    try {
      await store.adapter.run('DELETE FROM memory_relations WHERE source_id = ? OR target_id = ?', [id, id]);
      await store.adapter.run('DELETE FROM memory_revisions WHERE memory_id = ?', [id]);
      await store.adapter.run('DELETE FROM memory_entries WHERE id = ?', [id]);
      await store.adapter.exec('COMMIT');
    } catch (error) {
      await store.adapter.exec('ROLLBACK');
      throw error;
    }
  
    return { deleted: true, id };
  }

• src/mcp/tools/memory-store.js:155-170 (registration)

  Registration of the 'localnest_memory_delete' MCP tool, which calls memory.deleteEntry.

  registerJsonTool(
    ['localnest_memory_delete'],
    {
      title: 'Memory Delete',
      description: 'Delete a stored memory entry and all of its revisions.',
      inputSchema: {
        id: z.string().min(1)
      },
      annotations: {
        readOnlyHint: false,
        destructiveHint: true,
        idempotentHint: true,
        openWorldHint: false
      }
    },
    async ({ id }) => normalizeDeleteResult(await memory.deleteEntry(id), { id })
